Not more than one trap shall be permitted on a trap arm. Food waste disposers installed with a set of restaurant, com- mercial, or industrial sinks shall be connected to a separate trap. Each domestic clothes washer and each laundry tub shall be connected to a separate and independent trap, except that a trap serving a laundry tub shall be permitted to also receive the waste from a clothes washer set adjacent thereto. The vertical distance between a fixture outlet and the trap weir shall be as short as practicable, but in no case shall the tailpiece from a fixture exceed 24 inches (610 mm) in length. One trap shall be permitted to serve a set of not more than three single compartment sinks or laundry tubs of the same depth or three lavatories immediately adjacent to each other and in the same room where the waste outlets are not more than 30 inches (762 mm) apart and the trap is cen- trally located where three compartments are installed. FP The requirement for fixtures within the building 'o be trapped by a water seal (see Figure 1001.2a) has been plumbing codes for almost 100 years. The trap's main purpose is to eliminate the possibility of sewer gas from entering the confines of the room or building. The water Inlet Lower Dip Crown Wair Upper Dip FIGURE 1001.2A WATER SEAL TRAP - "P-TRAP" Trap Arm T----- 1 ' I seal, or trap seal, effectively accomplishes this by creating a barrier of 2 to 4 inches of water that prevents sewer gas from entering the room. A secondary benefit is that it prevents access of pests or vermin to drains, as well as access to the building through the fixture by way of the sewer system. Each fixture must be separately trapped. Some fixtures such as water closets and urinals have integral traps and do not require an additional trap since the water seal is built in its structure (see Figure 1001.2c). The trap arm, the piping from the end of the trap to the inner edge of the vent connection, may only serve one trap (see Figures 1001.2b and 1001.2d). This eliminates the pos- sibility of one trap being siphoned as the other fixture is used. The flow along the trap arm passing the other trap con- nection could siphon the unused trap. This is the reason why each trap must be protected by a separate vent as is required in Section 1002.2 and in Section 901.2, Vents Required. The continuous waste provides a method of draining multiple compartments to a single trap. The continuous waste is limited to up to three compartments, sinks or lava- tories, but only if they are within the 30 inch limitation. In a three -sink configuration the trap must be located undeUli?n center sink. This is to provide uniform draM sizing at shorten the distance to the trap and its drain (see Fig 1001.2e, 1001.2f and 1001.2g). The installation of a food waste disposal in a co cial kitchen is normally under the jurisdiction of a h department. In some areas, this installation may even prohibited. Commercial kitchen sinks will often be con- nected to a grease interceptor or hydromechanical device so depositing food waste into these devices will negatively affect their function. When they are allowed to be connect- ed to the drainage system they must be installed on a sepa- rate trap. This also means that they will have a separate trap arm, vent, and fixture drain. This will effectively separate the sink from the disposal, and if the disposal line becomes plugged, the sink will still function (see Figure 1001.2h). If a clothes washer and laundry tub are both to be 1 /4 bend Twin ell is not an approved fitting for drainage piping FIGURE 1001.26 TWO TRAPS ON ONE TRAP ARM - PROHIBITED 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 301 TRAPS AND INTERCEPTORS Floor -Mounted Water Closet Wall -Hung Water Closet FIGURE 1001.2C WATER CLOSET AND URINAL INTEGRAL TRAPS FIGURE 1001.2D TWO TRAPS ON ONE TRAP ARM - PROHIBITED 30" maximum (762 mm) 4 (762 mm) 30" maximum 3 • Compartment Sink FIGURE 1001.2E THREE COMPARTMENT SINK ON ONE TRAP installed in the same area, they must each have their own drainage connection. If a laundry tub, sometimes called a laundry tray or sink, is installed but there are no connec- tions for a clothes washer, then the clothes washer may be set next to the sink and drain into it. The laundry sink com- partment will be able to handle the pumped waste from the clothes washer because of its volume. The fixture tailpiece should be as short as possible to limit the fall of waste into the trap.

As the length of the column increases, so lso the velocity of the moving column of water, increasing .e momentum pull on the trap seal, Research has proven that limiting the tailpiece length to 24 inches will help to eliminate the possibility of the trap to self -siphon. The tail- piece may offset but the developed length of the tailpiece must not exceed 24 inches (see Figure 1001.2i). Other methods developed to eliminate self-siphonage of the trap are the limitation of trap arm lengths (see Section 1002.2) and the provision of a vent for the trap (see Section 1002.1). The clothes washer standpipe is not the tailpiece for a clothes washer. The standpipe for the clothes washer is considered to be an indirect waste receptor rather than a tailpiece and, therefore, is limited by Section 804.1, Standpipe Receptors, and not by this section of the code. 1002.0 Traps Protected by Vent Pipes. 1002.1 Vent Pipes. Each plumbing fixture trap, except as otherwise provided in this code, shall be protected against siphonage, backpressure, and air circulation shall be assured throughout the drainage system by means of a vent pipe installed in accordance with the requirements of this code. cmagirIl The section (see also Section 901.2) requires the trap to be protected from siphonage and backpressure by a vent (see Figure 1002.1), and that air circulation is assured throughout the system. Most of the measures to accomplish this are discussed in Chapter 9 and should be reviewed long with this chapter. The protection of the waterseal trap is assured upon a simple pneumatic principle, namely, equal atmospheric pressure must he maintained on both sides of the trap. When a trap is filled, the atmospheric pressure on the fix- ture side of the trap water seal is equal to the atmospheric pressure on the outlet side of the trap water seal. The vent connection to the trap arm maintains that equal pressure on the outlet side of the trap. As is discussed in Chapter 9, the vent system is designed to maintain pressure variation with- Straight Tailpiece in the system of plus or minus one -inch water column (.25 kPa). Pressures above or below that design pressure will cause a trap to lose its water seal. A positive pressure on the downstream side of the trap will cause air to blow through the trap seal, pushing its contents into the fixture. A negative pressure will siphon the trap seal into the trap arm and the draM. This allowable pressure variation of one -inch water column is a considerable factor of safety for a trap seal of 2 inches or greater. For example, if a trap seal has a depth of 2 inches (see Figure 1005.1) and is subjected to a negative pressure of one -inch water column, then the remaining trap seal depth would be I 1/2 inches. If the trap seal is 4 inches, then the remaining seal depth would be 31/2 inches. Hence, it would take a negative pressure of a four -inch water col- umn to siphon the water from a trap with a 2-inch seal below the dip of the trap, and eight -inches of water column to siphon a 4-inch seal below the dip of the trap. Designing a venting system according to Chapter 9 ensures consider- able safety margins by maintaining the pressure variations within ± one -inch water column. 1002.2 Fixture Traps. Each fixture trap shall have a pro- tecting vent so located that the developed length of the trap arm from the trap weir to the inner edge of the vent shall be within the distance given in Table 1002.2, but in no case less than two times the diameter of the trap arm. ...=11111 The effect of length of unvented fixture drains on self-siphonage was the subject of much research at the National Bureau of Standards [see Recommended Minimum Requirements for Plumbing BH13 (1928) and Self-Siphonage of Fixture Traps BMS126 (1951)]. One of the objectives of the research was to find the maximum length of a fixture drain without self -siphoning. This research demonstrated that the slope should be confined between the limits of 1/4 inch and 1/2 inch per foot and that the outlet end of the fixture drain should not extend below the weir of the trap. Hence, Table 1002.2 shows maximum horizontal lengths of trap arms calculated Offset Tailpiece Section 1001.2 does not prohibit an offset in a tailpiece. FIGURE 1001.21 LENGTH OF TAILPIECE 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 303 TRAPS AND INTERCEPTORS To Fixture FIGURE 1002.1 TRAP PROTECTED BY VENT using a grade of 1/4 inch per foot to an extent where the trap arm outlet will not be below the weir of the trap. For exam- ple, a I 1/4 inch trap arm may have a maximum horizontal distance of 30 inches without producing the effect of self- siphonage (see Figures 1002.2a and 1002.2b). The research also revealed the variations between short and long turn pattern fittings (sanitary tee and combination wye-eighth bend), the short turn fitting permitting the use of longer unvented lengths of fixture drains. Thus, the short turn fitting has better characteristics to prevent self- siphonage and is preferred when connecting a fixture drain to a vertical vent. The sanitary tee also allows the vent opening to remain above the trap weir. This better allows air into the trap ann while the fixture is draining and retards any momentum pull that could cause siphonage. Because the water closet and similar integrally trapped fixtures function as self-siphonage fixtures, their traps are an S-type. In this case, the trap arm length is calculated along the developed length of the piping from the top of the closet flange to the inner edge of the vent. Footnote 2 in Table 1002.2 stipulates for the water closet trap arm a max- imum length of 6 feet. This limitation is required whether the water closet trap arm is 3 inches in diameter or 4 inches. The same research discussed above also discovered that the vent could be placed too close to the weir of the trap. A style of venting the trap called the "crown vent" been used but it was found to be subject to clogging. Whc the fixture discharges, there is an upward vertical momen- tum of flow on the outlet side of the trap which would enter the vent if installed on the crown of the trap causing the vent to eventually foul and clog. Also, the vent at the crown of the trap or close to the crown is covered by the initial full flow into the trap arm and is useless to prohibit siphonage. Therefore, there is a minimum trap arm length requirement. The minimum length is two times the diame- ter of the trap ann. For example, the I 1/4 inch trap arm must have a minimum distance of 21/2 inches from the weir of the trap to the inner edge of the vent, Two times the diameter of the pipe effectively moves the inner edge of the vent away from the area of full flow in the trap arm and allows the vent to function properly (see Figure 1002.2c). 1002.3 Change of Direction. A trap arm shall be per- mitted to change direction without the use of a cleanout where such change of direction does not exceed 90 degrees (1.57 rad). Horizontal changes in direction of trap arms shall be in accordance with Section 706.3. Exception: For trap arms 3 inches (80 mm) in diameter and larger, the change of direction shall not exceed 135 degrees (2.36 rad) without the use of a cleanout. cm=11r/A very common installation of the trap arm is a 90-degree turn in the trap arm between the trap and the con- nection of the trap arm to the waste and vent (see Figur 1002.3). This is commonly called a "dirty arm." Researc has determined that a 90-degree elbow in a horizontal trap arm at a distance no greater than 18 to 20 inches from the vertical inlet of the trap actually reduces the self-siphonage effect (NBS, Recommended Minimum Requirements for Plumbing BH13). The 90-degree turn is allowable if the fit- ting used complies with Section 706.3, which states which fittings may connect horizontal lines with other horizontal lines. This essentially limits the 90-degree change of direc- tion to a long sweep or two 45-degree fittings. However, in TABLE 1002.2 HORIZONTAL LENGTHS OF TRAP ARMS (EXCEPT FOR WATER CLOSETS AND SIMILAR FIXTURES). 2 TRAP ARM PIPE DIAMETER (Inches) DISTANCE TRAP TO VENT MINIMUM (Inches) LENGTH MAXIMUM (inches) 11/4 21/2 30 11/2 3 42 2 4 60 3 6 72 4 8 120 Exceeding 4 2 x Diameter 120 For SI units: 1 inch = 25.4 mm Notes: I Maintain 1/4 inch per foot slope (20.8 mm/m). 2 The developed length between the trap of a water closet or similar fixture (measured from the top of the closet flange to the inner edge of the vent) and vent shall not exceed 6 feet (1829 mm). 304 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL TRAPS AND INTERCEPTORS Vent nner edge of vent Trap weir The trap arm is the pi between the trap weir and the Inner edge of the vent.

Caution is needed in 'sing the proper fitting in connecting the trap arm to the waste ,d vent connection. In the vertical position the sanitary tee FIGURE 1002.3 "DIRTY ARM" - USE ONLY DURHAM-STYLE FITTING will he the proper fitting for most installations. The use of a combination wye and one -eighth bend will not be allowed as it places the inner edge of the vent below the weir of the trap. See Figure 1002.4 for an improper use of a double wye and the improper length of clothes washer standpipes. 1003.0 Traps — Described. 1003.1 General Requirements. Each trap, except for traps within an interceptor or similar device shall be self cleaning. Traps for bathtubs, showers, lavatories, sinks, laundry tubs, floor drains, urinals, drinking fountains, dental units, and similar fixtures shall be of standard design, weight and shall be of ABS, cast -brass, cast-iron, lead, PP, PVC, or other approved material. An exposed and readily accessible drawn -copper alloy tubing trap, not less than 17 B & S Gauge (0.045 inch) (1.143 mm), shall be permitted to be used on fixtures discharging domestic sewage. Exception: Drawn -copper alloy tubing traps shall not be used for urinals. Each trap shall have the manufacturer's name stamped legibly in the metal of the trap, and each tub- ing trap shall have the gauge of the tubing in addition to the 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 305 TRAPS AND INTERCEPTORS FIGURE 1002.4 IMPROPER FITTINGS USED FOR VENT CONNECTION manufacturer's name. A trap shall have a smooth and uni- form interior waterway. c11111 The requirement for self-cleaning traps does not refer to any internal mechanism within the trap itself It sim- ply refers to the self -scouring potential that the flow rate of discharge has within the trap itself to prevent fouling. The P nap is already designed to be self-cleaning or self -scouring if sized correctly. Although an increase of trap seal depth reduces the potential for self-siphonage, it will also decrease the scouring properties by reducing the rate of flow through the trap. A drum trap is an example of a trap that is not self- cleaning (see commentary for Section 1004.1). Traps are part of the drainage system and must be approved for drainage materials listed. The brass tubing trap of not less than 17 Brown and Sharp (B&S) sheet metal gauge must be readily accessible. The trap gauge is thicker than the allowable continuous waste gauge of 20 B&S gauge because the trap will hold waste water continu- ously and must be more resistant to corrosion than the con- tinuous waste or tailpiece. The use of drawn brass traps for urinals is not allowed because of the corrosive contents (urine) of the liquid waste in the urinal trap. Each trap must also be readily identifiable not only for the installer but for the inspector and mainte- nance personnel. 1003.2 Slip Joint Fittings. A maximum of one approved slip joint fitting shall be permitted to be used on the outlet side of a trap, and no tubing trap shall be installed without a listed tubing trap adapter. Listed plastic trap adapters shall be permitted to be used to connect listed metal tubing traps. ..71111'11 Slip joints are limited on each trap arm to one slip joint fitting after the P trap. This would allow the slip joint on a trap arm extension or a 45-degree offset, Remodeling a sink cabinet is an application where such a slip joint may he needed. The new cabinet may offset the fixture trap from the waste connection. To reconnect the trap to the existing trap adapter, a slip extension piece or 45-degree offset slip joint may be needed. An approved trap adapter must be used at the connection of the trap arm to the drainage fitting. Whether it is a plastic pipe end or a galvanized nipple, a trap adapter must be used. The adapter prevents the trap arm from extending too far down the drainage pipe or, if placed close to the waste and vent connection, from passing into the drainage fitting and blocking the waste or airflow (see Figure 1003.2). FIGURE 1003.2 TRAP ADAPTER - NOTICE STOP FOR P-TRAP ARM 1003.3 Size. The size (nominal diameter) of a trap for a given fixture shall be sufficient to drain the fixture rapidly but in no case less than nor more than one pipe size largk than given in Table 702.1. The trap shall be the same size as the trap arm to which it is connected. Trap sizes are generally based on the size of the fixture outlet. The size of the trap and trap arm should cor- respond to the size of the fixture outlet to provide proper discharge flow rate and prevent overflowing or sluggish drainage. If the trap is smaller than what is required in Table 702.1 Drainage Fixture Unit Valves (DFU), then the effect of self-siphonage would increase. If it is oversized more than one pipe size, then the flow from the fixture would not be enough to provide the proper scouring or cleaning effect for the trap. However, allowing the trap to increase only one size larger than the minimum require- ment will not significantly affect the scouring ability of the trap and will also decrease the effect of self-siphonage. For example, a kitchen sink trap that is a minimum of 11/2 inches can be increased to 2 inches. This would allow a longer trap ai-rn developed length. Notice that this section requires the trap to be the same size as the trap arm. If the option to use a 2-inch trap arm is selected, this code section also mandates that a 2-inch trap be installed. A 2-inch trap could not be used with a 11/2-inch trap ami as this would be an obstruction to flow prohibited in Chapter 3. 1004.0 Traps. 1004.1 Prohibited. No form of trap that depends for i' seal upon the action of movable parts shall be used. No tr 306 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL TRAPS AND INTERCEPTORS that has concealed interior partitions, except those of plas- tic, glass, or similar corrosion -resisting material, shall be sed. "S" traps, bell traps, and crown -vented traps shall be zohibited. No fixture shall be double trapped. Drum and bottle traps shall be installed for special conditions. No trap shall be installed without a vent, except as otherwise pro- vided in this code. ..m=111111 Manufacturers have produced various kinds of traps in the past and continue to do so with innovative designs. However, not all designs have been found favor- able for a safe plumbing system. Certain anti -siphon traps have been designed with movable parts or mechanical means to maintain its trap seal (see Figure 1004.1a). The problem with these types of traps is that they may foul and malfunction over time since they are not self -cleansing. Traps with interior partitions are permitted only if the parti- tion is of noncorrosive material (see Figure 1004.1b). Interior partitions are not visible and if the partition cor- rodes, the trap seal will be lost without notice. The unsuitability of crown vented traps to be used in the drainage system has already been discussed in Section 1002.2, and the S trap is ineffective in protecting the trap seal because the arrangement of the S trap makes the trap seal too susceptible to siphonage (see Figure 1004.1e). The bell trap (see Figure 1004.1d) consists of a cup with a standpipe in the middle over which is a bell that dips into the water contained in the cup to form a seal. Also, this trap is not self -cleansing, the seal depth is very shallow -)ften less than one-half inch), and it is known to be very tuggish in draining. Drum and bottle traps (see Figures 1004.1e and 1004.1f) may be installed only when permitted by the Authority Having Jurisdiction (AHJ) for use under special conditions. Drum traps are used as sediment traps, separat- FIGURE 1004.1A ANTI -SIPHON TRAPS FIGURE 1004.1B TRAP WITH INTERIOR PARTITION ing out small solids before they enter the drainage system. The bottle trap is similar to the P trap, but with a slightly different configuration and is somewhat more prone to siphonage than the P trap. It is smaller than the P trap and used where space saving is necessary. These traps may still be used upon approval but there should be a valid reason. When a fixture is double trapped, the piping between the two traps could become air bound, resulting in a slow drain and increasing the possibility of a stoppage. There is also the possibility of one or both of the traps being siphoned by the flow through them; therefore, no fixture may be double trapped. 1004.2 Movable Parts. Bladders, check valves or other type of devices with moveable parts shall be prohibited to serve as a trap. €3..=9111This section prohibits movable parts that maintain a trap seal. Some traps have been manufactured to function without liquid seals. These traps utilize a bladder or FIGURE 1004.1C S-TYPE AND CROWN VENTED TRAPS - PROHIBITED FIGURE 1004.1D BELL TRAP 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 307 TRAPS AND INTERCEPTORS FIGURE 1004.1E DRUM TRAP FIGURE 1004.1F BOTTLE TRAP diaphragm mechanism that is typically closed to seal off sewer gas while allowing expansion of the diaphragm when there is discharge of water. Similarly, check valves do not rely on trapped water to prevent the emission of sewer gas. Although these products may be initially effective, there still exist conditions where fouling may cause the movable parts to no longer seal tight and allow the emission of gases. 1005.0 Trap Seals. 1005.1 General. Each fixture trap shall have a liquid seal of not less than 2 inches (51 mm) and not more than 4 inch- es (102 mm), except where a deeper seal is found necessary by the Authority Having Jurisdiction. Traps shall be set true with respect to their liquid seals and, where necessary, they shall be protected from freezing. cm=1111 The water seal that forms the trap barrier is the maximum vertical depth of liquid that a trap will retain. It is measured between the crown weir and the top of the dip of the trap. A water seal of not less than two inches and not more than four inches was found to be the optimum depth to provide the necessary protection against sewer gas and still provide the self -scouring effect needed to keep the trap from fouling (see Figure 1005.1). A trap with less than two -inches of seal depth offers less resistance to self- siphonage and more readily loses its seal by evaporation. Obviously the greater the seal depth, the opposite is propor- tionately true. Traps for special equipment or circumstances, such as a grease interceptor, may have a deeper trap seal but these are usually for commercial or industrial applications th• require a greater depth. Also, in most of these cases the tn. seal is not in a P-trap but in the depth of water in a tank. The trap must be set true (level) with respect to the liq- uid bound in the trap. This means that the water columns on both sides of the trap must be level with each other on the same horizontal plane of the trap weir. If not, the depth of the trap seal will be compromised with a lesser depth, reducing protection from backpressure or siphonage. FIGURE 1005.1 STANDARD TRAP SEAL AND DEEP SEAL TRAP 1006.0 Floor Drain Traps. 1006.1 General. Floor drains shall connect into a trap so constructed that it can be readily cleaned and of a size to serve efficiently the purpose for which it is intended. The drain inlet shall be so located that it is in full view. Where subject to reverse flow of sewage or liquid waste, such drains shall be equipped with an approved backwater valve. 0==r11 Floor drains arc usually an emergency device placed in the floor to catch the overflow from sinks or equipment. Because they are at floor level they could even- tually collect sediment or other debris in the trap. If there is any flow at all into most floor drain traps, it will be a very low or intermittent flow and not enough to provide a scour- ing action in the trap. Sediment may build up and eventual- ly plug the trap; therefore, they must be installed in open sight for the ability to service them. 1007.0 Trap Seal Protection. 1007.1 General. Floor draM or similar traps directly con- nected to the drainage system and subject to infrequent u' shall be protected with a trap seal primer, except where i. 308 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL TRAPS AND INTERCEPTORS deemed necessary for safety or sanitation by the Authority Having Jurisdiction. Trap seal primers shall be accessible '1r maintenance. 1Floor drain traps that do not connect to a water - supplied fixture will tend to evaporate. Other traps that are not periodically used or are installed in overly dry areas will lose their seal by simple evaporation. The result of this loss of trap seal allows known health hazards such as hydrogen sulfide, methane, bacteria, viruses and mold to enter the living space. The SARS epidemic (Severe Acute Respiratory Syndrome) reported in Hong Kong, China in 2003 caused in part by a dry and leaking trap, has raised the awareness of the dangers of an unprotected sanitary drainage system. One of the first lines of defense against trap failure is the trap primer, which is a piping device that helps to main- tain a water seal in a remote trap, A trap primer connects to a cold water inlet or other water supply. Every time that inlet or supply is used, a small amount of water flows down to the trap to keep the water seal from drying up. If the primer is electronic, it is set on a timer that daily releases enough water to maintain the trap seal (see Figures 1007.1a and 1007.1b). It is clear that traps can easily dry up in rooms where floor drains are seldom used, but it may not be obvious that traps dry up in rooms that are used daily. This is a common problem in mechanical and service rooms, which are often dry and overly warm. Years ago, traps would be regularly plenished on the janitor's nightly rounds. Enough of the ,oapy water from those old fashioned heavy mops would go down the floor draM to replenish the trap. Today, with the popularity of dry chemicals for cleaning, not much water is used on the floors, at least not enough to keep the CHECK VALVE SEAL VACUUM BEAKER PORTS THE PRIMING VALVE MUST HAVE A MINIMAL ELEVATION OF 12 INCHES ABOVE THE FINISHED FLOOR AVOID DIRECT INSTALLATION TO PREVENT FOREIGN MATERIAL FROM ENTERING DIRECTLY INTO THE PRIMER TRAP PRIMER VALVE traps seal full. By providing a trickle of water every time water is used, trap seal primers refill the seal of a P-trap. Making the correct choice of which trap primer to use should take some thought. There are three main kinds of trap seal primers: 1. Pressure drop activated. 2. Flush valve operated. 3. Multiple and electronic activated. Pressure -drop -activated trap seal primers are usually brass, have a one -half -inch Mail Iron Pipe (MIP) inlet con- nection, and one -half -inch Female Iron Pipe (FIP) outlet connection. An interior cartridge seals when the line pres- sure is in a static state, but when the line pressure drops just three psi (20.68 kPa) by the flushing of a toilet, a faucet opened, etc., the cartridge will rise. It rises because a pres- sure differential has occurred within the primer. At this point, a metered amount of water is discharged under pres- sure into the line connected to the floor drain trap. Pressure drop activated trap seal primers are designed to minimize the problem of clogging. These trap seal primers are constructed with a fine mesh filter, keeping line debris at bay. The flush -valve -operated trap seal primer gets its name from its installation (see Figure 1007.1c). It is placed below the flush valve on a water closet or urinal and con- nects to the floor drain by a tube so that the tube can catch some of the water discharged from the flush valve. The water runs down the tube to the floor drain and the water seal is maintained. This trap seal primer has two positive features: 1) low water consumption since it only uses a por- tion of the discharged water from the flush valve operation, and 2) no moving parts. However, this trap seal primer also VACUUM BREAKER PORTS FIGURE 1007.1A TRAP SEAL PRIMER RECOMMENDED INSTALLATION 1111-Ztrrinit • • 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 309 TRAPS AND INTERCEPTORS introduces some restrictions. Its use may not be practical because the flush -valve may be situated too far from the floor drains. In this case, a pressure -drop -activated trap primer is more practical since it can be installed close to the drain that needs to be primed. When a number of pressure -drop -activated trap seal primers are located close to one another, they can be primed via a multiple trap primer (see Figure 1007.1d), In this case, a metered amount of water from the trap primer is evenly distributed to more than one floor drain trap by means of a distribution unit or an electronic primer mani- FIGURE 1007.1B PRIMER CONNECTION TO FLOOR DRAIN PREPARED FOR CONCRETE POUR Finished Wall • 2-1/4" H i I Fresh II Water I Make-UpI; Line Flush Valve Trap Primer 1-1/2" x 12'17 Gauge Flush Valve Primer Tube with 1/2" Compression Fitting Finished Floor 1/2 OD Kial;-41tiiiiiiitine fold. For every 20 feet of floor drain trap make-up water line, the primer must be a minimum of 1 foot elevation from the finished floor. It should generally be mounte- level with the water supply line. These multiple units can be installed in a variety of sit- uations. For example, such a unit is useful when a men's restroom is located next to a women's restroom. In this instance, one trap seal primer can serve both floor drain traps, omitting the need for additional trap primers, extra shutoff valves, another access door and air gap fittings, which saves time, money, and labor. They can also be installed with an electronic timer to provide automatic fill- ing of the trap seal. In this installation there is no worry about having enough pressure drop or use of the fixtures to keep the trap filled. The trap primer must be accessible. The access door needs to be large enough to allow the plumber to reach the trap seal pruner, the line shutoff valve and any other acces- sories present. Installing a line shutoff valve will make repair and maintenance that much easier. 1008.0 Building Traps. 1008.1 General. Building traps shall not be installed except where required by the Authority Having Jurisdiction. Each building trap where installed shall be provided with a cleanout and with a relieving vent or fresh - air intake on the inlet side of the trap, which need not be larger than one-half the diameter of the drain to which it connects. Such relieving vent or fresh -air intake shall be carried above grade and terminate in a screened outh located outside the building. ..m71111Bui1ding traps (see Figure 901.2i) are generally not installed although there may be reasons for their inclu- sion in the building sewer. Therefore the code allows the Floor Drain FIGURE 1007.1C FLUSH VALVE TRAP PRIMER 5' Shallow Chrome Flange P-trap 1/2" Chrome Plated Trap Primer Line 1/2 x 12" 310 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL TRAPS AND INTERCEPTORS FIGURE 1007.1D MULTIPLE TRAP PRIMER INSTALLATION AHJ to make the determination when they are necessary. Some of the reasons for prohibiting building traps are: 1) it Iterferes with the flow of sewage and air movements in the plumbing system; 2) it reduces the carrying capacity of the building drain due to the added resistance; 3) it increases the potential of back pressure in the soil stack; and 4) it reduces the ventilation of the street sewers. Some of the reasons for permitting the use of building traps are: 1) it affords an additional barrier against adrnis- sion of sewer gas in case of trap evaporation or leakage; 2) it is needed in very cold climates to prevent frost closure of a vent terminal by reducing the circulation of air coirnmuni- INLET cated from the street sewer through the plumbing system; 3) it prevents exposing neighboring occupants from foul odors communicated through a vent terminal where build- ings are in close proximity to each other. The building trap is also used where there is a com- bined sewer and storm system (see Section 1101.15). Sewer gas is not permitted into the storm drainage system by the use of a building trap installed on the main storm drain before the wye connection to the combined building sewer. The Code does not require a fresh air inlet for a building storm drain trap, but a cleanout has to be provided on the outlet side of the trap. 1009.0 Interceptors (Clarifiers) and Separators. 1009.1 Where Required. Interceptors (clarifiers) (including grease, oil, sand, solid interceptors, etc.) shall be required by the Authority Having Jurisdiction where they are necessary for the proper handling of liquid wastes con- taining grease, flammable wastes, sand, solids, acid or alka- line substances, or other ingredients harmful to the building drainage system, the public or private sewer, or to public or private sewage disposal. assMiln Interceptors and separators serve a different purpose than fixture traps in that they protect the drainage and sewer systems from the introduction of substances that might be harmful to those systems. An interceptor or separator is a device designed and installed to separate, retain and treat deleterious, hazardous and undesirable matter before they enter the sewer system (see Figure 1009.1). Normal sewage or liquid wastes bypass these devices and discharge into the sewer system via the build- ing drain and sewer. If large amounts of grease, soaps and oils enter a sewer system, the materials will coagulate, solidify and adhere to the inside wall of the pipe, eventually blocking or partially blocking the pipe. Similarly, solids such as sand, plaster, metal chips and stones will cause stoppages or partial stop- pages if peiiiiitted to enter the system. Oils, kerosene, gaso- line, naphtha and paraffin present the danger of fire and FIGURE 1009.1 INDUSTRIAL INTERCEPTOR OUTLET 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 311 TRAPS AND INTERCEPTORS explosion in sewer piping. Acids, alkalis and other chemi- cal wastes in concentrated amounts could attack the piping through corrosion. In addition, all of the above are detri- mental to proper functioning of sewage treatment plants, both public and private, and must be collected and treated before they discharge to the sewer system. There are three principal methods of intercepting and treating these unwanted wastes. They are: 1. Floatation. Gasoline, oil, grease and other volatile liquids are lighter than water and are not readily soluble in water. They tend to separate out of the liquid waste and float to the top of the container where they can then be collected and removed. Hydrornechanical grease interceptors, gravity grease interceptors and oil or gas interceptors are examples of devices that use floatation as a primary method of separation. 2. Sedimentation. Sand and other solids, which are heavier than water and also are not soluble in water, tend to settle out of the waste water to the bottom of the container. The solids can then be puinped or vacuumed out of the intercep- tor. Sand interceptors, septic tanks and drum traps for smaller installations are examples of devices that use sedi- mentation as the primary method of separation. 3. Neutralization. Chemical wastes that could be detrimental to the sewage system in concentrated amounts must be neu- tralized before entering the sewer system. Chemical waste is collected before entry into the sewer and treated or neutral- ized before being discharged to the sewer. Acid neutralizing tanks and other such devices are examples of systems that use neutralization as the primary method of separation. Occasionally, waste with high concentrations of grease or emulsified grease may require further treatment, such as additional settling, rock filtration and chemical or mechani- cal treatment to remove the grease. There are many instances where one of the three methods or a combination of methods for treating these wastes is needed. Examples of the use of these devices are: restaurants, hotels, cafeterias, schools, hospitals and institutional or commercial buildings where food is served in great quanti- ty may produce grease in sufficient amounts to warrant the installation of grease interceptors; dairies, slaughterhouses and commercial food -processing plants have grease and fats as byproducts and require interceptors; gasoline service stations, garages, automobile repair shops, laundries, dry- cleaning plants, machine shops and industries using chemi- cal processing are sources of flammable and volatile wastes that must be removed and treated; machine shops, garages, service stations, hospitals, medical clinics, dental laborato- ries and fish preparation areas contribute solids such as metals, plaster, sand and fish scales; hair and lint intercep- tors may be necessary in beauty salons, barbershops, surgi- cal preparation rooms and veterinary facilities; and dental laboratories and jewelry manufacturers may require inter- ceptors for the recovery of precious metals. Separators and interceptors will be designed by the manufacturer and the installation location designated by a plumbing engineer or design professional. The plumber's or plumbing contractor's responsibility is to install the sys- tem properly. In addition to the manufacturer's installation instructions, the following sections provide guidance for the installation of the interceptor or separator. 1009.2 Approval. The size, type, and location of eaci. interceptor (clarifier) or separator shall be approved by the Authority Having Jurisdiction. Except where otherwise specifically permitted, no wastes other than those requiring treatment or separation shall be discharged into an intercep- tor (clarifier). 1009.3 Design. Interceptors (clarifiers) for sand and simi- lar heavy solids shall be so designed and located as to be readily accessible for cleaning and shall have a water seal of not less than 6 inches (152 mm). 1009.4 Relief Vent. Interceptors (clarifiers) shall be so designed that they will not become air -bound where closed covers are used. Each interceptor (clarifier) shall be proper- ly vented. 1009.5 Location. Each interceptor (clarifier) cover shall be readily accessible for servicing and maintaining the interceptor (clarifier) in working and operating condition. The use of ladders or the removal of bulky equipment in order to service interceptors (clarifiers) shall constitute a violation of accessibility. Location of interceptors (clari- fiers) shall be shown on the approved building plan. 1009.6 Maintenance of Interceptors. Interceptors shall be maintained in efficient operating condition by peri- odic removal of accumulated grease, scum, oil, or other floating substances and solids deposited in the interceptor. 1009.7 Discharge. The waste pipe from oil and sari( interceptors shall discharge as approved by the Authority Having Jurisdiction. 1010.0 Slaughterhouses, Packing Establishments, etc. 1010.1 General. A fish, fowl, and animal slaughterhouse or establishment; a fish, fowl, and meat packing or curing establishment; a soap factory, tallow -rendering, fat -render- ing, and a hide -curing establishment shall be connected to and shall drain or discharge into an approved grease inter- ceptor (clarifier). 1011.0 Minimum Requirements for Auto Wash Racks. 1011.1 General. A private or public wash rack, or floor or slab used for cleaning machinery or machine parts shall be adequately protected against storm or surface water and shall draM or discharge into an approved interceptor (clarifier). 1012.0 Commercial and Industrial Laundries. 1012.1 General. Laundry equipment in commercial and industrial buildings that does not have integral strainers shall discharge into an interceptor having a wire basket or similar device that is removable for cleaning and that will prevent passage into the drainage system of solids 1/2 of an inch (12.7 min) or larger in maximum dimension, such as string, rags, buttons, or other solid materials detrimental to the public sewerage system. 1013.0 Bottling Establishments. 312 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL TRAPS AND INTERCEPTORS 1013.1 General. Bottling plants shall discharge their pro- cess wastes into an interceptor that will provide for the sep- -ation of broken glass or other solids, before discharging fluid wastes into the drainage system. 1014.0 Grease Interceptors. - 1 Prior to the 2000 UPC, the term "grease trap" was used to identify almost any installation that provided fats, oils or grease (FOG) removal. The grease trap was actually used to provide the fixture trap for one fixture if certain requirements were met. However, research discovered that the fixture trap did a better job of protecting the trap seal so the use of the grease trap as a fixture trap was eliminated. Because of the fact that the grease trap is not a fixture trap and in order to create a uniform description of these devices, the 2003 UPC termed them "grease interceptors." The UPC identifies four separate types of devices used in the collection, retention and disposal of FOG. They may be used separately or in combination to create a complete FOG removal and disposal system. For convenience, they are listed here with their definition from Chapter 2. I. Hydromechanical Grease Interceptor - A plumbing appurtenance or appliance that is installed in a sanitary drainage system to intercept nonpetroleum fats, oil, and grease (FOG) from a wastewater discharge and is identi- fied by flow rate, and separation and retention efficiency. The design incorporates air entrainment, hydromechanical separation, interior baffling, or barriers in combination or separately, and one of the following: - External flow control, with air intake (vent), directly connected B - External flow control, without air intake (vent), directly connected C - Without external,flow control, directly connected D - Without external flow control, indirectly connected these interceptors comply with the requirements of .Table 1014.2,1. Hydromechanical grease interceptors are gener- ally installed inside. The hydromechanical grease interceptor (HGI) is a smaller device and is basically what was referred to as the "grease trap," as earlier models did in fact function as the fixture trap (see Figure 1014.0a). The term "hydromechan- ical" refers to the use of air -injecting flow controls, counter flow baffles and barrier baffles along with the natural buoy- ancy of FOG to accomplish its function of FOG separation. 2. Grease Removal Device (GRD) - A hydromechanical grease interceptor that automatically, mechanically removes non -petroleum fats, oils and grease (FOG) ,from the interceptor, the control of which are either automatic or manually initiated. The grease removal device (GRD) (see Figure 1014.0b) not only separates the FOG from the wastewater but also removes the FOG from the interceptor. Normally, a hydromechanical grease interceptor (HGI) design is used in conjunction with the method of removing the FOG. There are two basic types of GRDs: a. Timer controlled. This typically utilizes a disk or belt that passes through the FOG layer and a squeegee device to wipe the accumulated FOG from the disk or belt into a drain trough and into a FOG receptacle. Other means of removing the FOG include a pump or gravity flow activat- ed by the timer. b. Sensor -controlled devices. These sense the presence of FOG and initiate the removal process only when necessary and as often as necessary. The GRD can always keep the retained FOG below the rated capacity of the device. They use valving and gravity or pump -assisted FOG removal. 3. Gravity Grease Interceptor - A plumbing appurtenance or appliance that is installed in a sanitary drainage system to intercept nonpetroleum fats, oils, and greases (FOG) from a wastewater discharge and is identified by volume, 30-minute retention time, baffle(s) not less than two com- partments, a total volume of not less than 300 gallons FIGURE 1014.0A HYDROMECHANICAL GREASE INTERCEPTOR DESIGN AND OPERATION 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 313 TRAPS AND INTERCEPTORS (1135 L), and gravity separation. [These interceptors com- ply with the requirements of Chapter 10 or are designed by a registered professional engineer.] Gravity grease inter- ceptors are generally installed outside. The gravity grease interceptor is normally a large vol- ume tank constructed of steel, concrete, fiberglass or plas- tic. It separates FOG from wastewater by gravity alone. The FOG -entrained wastewater enters the tank using tee baffles to direct the flow below the floating FOG level in order to leave the floating FOG undisturbed. Retention time is used to separate the FOG from the wastewater by floatation (see Figures 1009.1 and 1014.3). 4. FOG Disposal System — A grease interceptor that reduces nonpetroleum fats, oils, and grease (FOG) in efflu- ent by separation, mass, and volume reduction, The FOG disposal system usually employs the HGI method for separating out the FOG. Disposal or remedia- tion of FOG is accomplished by thermal, chemical. electri- cal or biochemical means. Each method attempts to change the molecular composition of the FOG to render it harmless or to enhance the digestion of the FOG as it is retained in the interceptor. 1014.1 General. Where it is determined by the Authority Having Jurisdiction that waste pretreatment is required, an approved type of grease interceptor(s) in accordance with ASME A112.14.3, ASME A112.14.4, CSA B481, PDI G- 101, or PDI G-102, and sized in accordance with Section 1014.2.1 or Section 1014.3.6, shall be installed in accor- dance with the manufacturer's installation instructions to receive the drainage from fixtures or equipment that pro- duce grease -laden waste located in areas of establishments where food is prepared, or other establishments where grease is introduced into the drainage or sewage system in quantities that can effect line stoppage or hinder sewage treatment or private sewage disposal systems. A combina- tion of hydromechanical, gravity grease interceptors, and engineered systems shall be allowed in order to meet this Greasy Effluent Rises Through Strainer Inlet }low Solid, Trarped In Solid, Chainl.et iViper Blade Assembly StoutuangWw aest kto: code and other applicable requirements of the Authority Having Jurisdiction where space or existing physical con- straints of existing buildings necessitate such installationF A grease interceptor shall not be required for individua dwelling units or for private living quarters. Water closets, urinals, and other plumbing fixtures conveying human waste shall not draM into or through the grease interceptor. cm=1111Although much FOG is created in residential kitchens and disposed of by draining to the sanitary drainage system, there is no requirement for individual residential grease interceptors. Human waste from the drainage system must bypass the interceptor. Adding this waste to the inter- ceptor will render it useless by overfilling it with solids. 1014.1.1 Trapped and Vented. Each fixture discharg- ing into a grease interceptor shall be individually trapped and vented in an approved manner. 1014.1.2 Maintenance. Grease interceptors shall be maintained in efficient operating condition by periodic removal of the accumulated grease and latent material. No such collected grease shall be introduced into drainage pip- ing or a public or private sewer. Where the Authority Having Jurisdiction determines that a grease interceptor is not being properly cleaned or maintained, the Authority Having Jurisdiction shall have the authority to mandate the installation of additional equipment or devices and to man- date a maintenance program. awv=11111 Maintenance is the most difficult part of the FOG removal system. The installation of these systems is man- dated by codes and it is relatively easy to check compli ance. However, ensuring that the maintenance of these sys- tems is accomplished is another matter. Although their maintenance is mandated, it is difficult, if not impossible, to ensure that it is being done. A poorly maintained system is as useful as no system at all. When maintaining these systems two factors must be addressed — service interval and FOG disposal. If the ser- vice interval is too long, the FOG will either simply pass Timer /Motor/ Electrical Ens loaire n• f",0 r /mei F r.r4 T161,1181t rtrom r), FIGURE 1014.0B GREASE REMOVAL DEVICE Outlet Clean Water Flow 314 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL TRAPS AND INTERCEPTORS through the overloaded interceptor or begin to breakdown into other harmful compounds. Long-term storage of FOG a large interceptor can create a dangerous condition. The reation of hydrogen sulfide is a byproduct of FOG decom- position and could lead to the corrosion of piping and the interceptor itself, not to mention that it is a lethal gas if it escapes the system. The development of the GRD and the FOG disposal system is a result of this maintenance problem. They can at least eliminate some of the maintenance problems by removal or remediation of the FOG. However. these devices do not solve all the maintenance issues. The devices will still need to be cleaned periodically and solids that have entered the interceptor removed. 1014.1.3 Food Waste Disposers and Dishwashers. No food waste disposer or dishwasher shall be connected to or discharge into a grease interceptor. Commercial food waste disposers shall be permitted to discharge directly into the building's drainage system. Exception: Food waste disposers shall be permitted to dis- charge to grease interceptors that are designed to receive the discharge of food waste. ...MI The only time a food waste disposer should dis- charge to a grease interceptor is when the grease interceptor is specifically designed to accept food waste. Otherwise, a food waste disposer should never discharge to a grease interceptor as such a discharge can cause the grease inter- ceptor to fail. The solids from the disposal will become utrained in the interceptor and begin to fill it unless ...leaned out. If a disposal is connected to the grease inter- ceptor not designed to receive food waste, a solids intercep- tor must precede the grease interceptor. The entrance of soapy water from a dishwasher into the interceptor will also be harmful to the system. The chemicals in dishwater will adversely affect the function of the interceptor and must be kept from the system. 1014.2 Hydromechanical Grease Interceptors. Plumbing fixtures or equipment connected to a Type A and B hydromechanical grease interceptor shall discharge through an approved type of vented flow control installed in a readily accessible and visible location. Flow control devices shall be designed and installed so that the total flow through such device or devices shall at no time be greater than the rated flow of the connected grease interceptor. No flow control device having adjustable or removable parts shall be approved. The vented flow control device shall be located such that no system vent shall be between the flow control and the grease interceptor inlet. The vent or air inlet of the flow control device shall connect with the sanitary drainage vent system, as elsewhere required by this code, or shall terminate through the roof of the building, and shall not terminate to the free atmosphere inside the building. Exception: Listed grease interceptors with integral flow controls or restricting devices shall be installed in an acces- tile location in accordance with the manufacturer's instal - ion instructions. ,.,711r1 The hydromechanical grease interceptor (HGI) uses the principles of fluid dynamics by taking advantage of air entrained in the effluent through the use of the vented flow control (see Figure 1014.2a). The FOG -laden wastewater passes through the flow control on its way into the interceptor. As the effluent passes through the orifice of the flow control, air is introduced to the flow from the air vent. Upon entering the interceptor, the effluent is directed through the separation chamber. The entrained air will sep- arate from the effluent quickly and then accomplishes two tasks. The escaping air accelerates the separation of FOG as it rises rapidly to the surface of the water in the separation chamber. The rising air burbles literally pull the FOG glob- ules to the top of the water. The released air then provides a small amount of positive pressure above the contents of the separation chamber to regulate the internal running water level of the grease interceptor, keeping it from becoming air bound. A flow control shall be installed on each fixture dis- charging to the HGI. A single flow control is allowed for multiple fixtures as long as the resulting total flow from the fixtures meets the capacity requirements of Section 1014.2.1 (see Figure 1014.2b). There should also be no fix- ture vent between the flow control and the interceptor. This would allow too much air to be entrained into the flow. The placement of the flow control is vitally important to the functioning of the interceptor. It should be placed as close as possible to the fixture. There should be as little vertical height as possible between the fixture outlet and the flow control. If the flow control is placed well below the fixture, the added head pressure above the flow control will render the flow control useless as it will increase the flow through the system (see Figure 1014.2c).

Divide the volume by 231 to calculate the volume of liquid in gallons. Per Example 1014.2.1, multi- ply the gallons by the fill factor .75. This fill factor takes into account that the fixture is normally filled to about 75 percent of capacity, with the other 25 percent being dis- placed by the items placed in the fixture for washing. Therefore, the actual drainage load is 75 percent of the fix- ture capacity. Once the actual drainage load is calculated, determine the flow rate per minute using a one minute or two minute drainage period. Typically, sinks will drain within a one - minute period, which determines the drainage load in gal- lons per minute. When would the two -minute drainage period be used? When the capacity of the fixtures (in gallons) discharging into the interceptor is 2'/2 times the flow rate capacity of the HGI, a two -minute drainage period would be used.

A smaller interceptor may be used, but the consequence is a longer drainage period. For example, a four -compartment sink is to discharge into a EIGI. Each compartment size is 24x24x12. Using the method described in the first paragraph, the actual drainage load is 89.8 gallons. Using the drainage period of one minute, a HGI equal to or greater than 89.8 gpm would be required (a typical size is 100 gpm). Suppose a 100 gpm interceptor would not fit due to space limitations. The Code would allow a 50 gpm interceptor with the acceptance that the fixtures would take longer to drain. Instead of one minute, the drainage period would be extended to two minutes. Remember, the flow control device will not allow the dis- charge rate to exceed 50 gprn. The drainage load of 89.8 gal- lons is within 21/2 times the flow rate of 50 gpm. If the capaci- ty of the fixtures had exceeded 125 gallons, then a 50 gpm interceptor would not be permitted. 1014.2.2 Vent. A vent shall be installed downstream of hydromechanical grease interceptors in accordance with the requirements of this code. .1.1.711111 The HGI itself must be vented to keep it from becoming air bound (see Figure 1014.2a). 1014.3 Gravity Grease Interceptors. Required gravity grease interceptors shall comply with the provisions of Section 1014.3.1 through Section 1014.3.7. 0..=.11 The gravity grease interceptor, as stated earlier, is a large volume tank with two sections. Its function is rel- atively simple. The effluent enters the tank through a baf- fled tee so as to not disturb the accumulated FOG floating at the top of the water level. The effluent is retained in the initial chamber until flow forces it into the next chamber and eventually out to the sewer. The FOG is separated by gravity — the FOG floats to the top of the water level. The tank is sized to allow enough retention time to permit the FOG to separate. A sampling box is installed in the outflow line to enable maintenance personnel to check on the functioning AIR INTAKE VENT FLOW REGULATORY DEVICE I .101 TYP.

The following sections give guidance to the design, location, and installation of the gravity grease interceptor (see Figure 1014.3). 1014.3.1 General. The provisions of this section shai_ apply to the design, construction, installation, and testing of commercial kitchen gravity grease interceptors. 1014.3.2 Waste Discharge Requirements. Waste dis- charge in establishments from fixtures and equipment which contain grease, including but not limited to, scullery sinks, pot and pan sinks, dishwashers, soup kettles, and floor drains located in areas where grease -containing mate- rials exist, shall be permitted to be drained into the sanitary waste through the interceptor where approved by the Authority Having Jurisdiction. 1014.3.2.1 Toilets and Urinals. Toilets, urinals, and other similar fixtures shall not drain through the interceptor. 1014.3.2.2 Inlet Pipe. Waste shall enter the interceptor through the inlet pipe. 1014.3.3 Design. Gravity interceptors shall be construct- ed in accordance with the applicable standard in Table 1701.1 or the design approved by the Authority Having Jurisdiction. 1014.3.4 Location.

Location of the grease interceptor shall meet the approval of the Authority Having Jurisdiction. 1014.3.4.1 Interceptors. Interceptors shall be placed as close as practical to the fixtures they serve. 1014.3.4.2 Business Establishment. Each business establishment for which a gravity grease interceptor is required shall have an interceptor which shall serve that estab- lishment unless otherwise approved by the Authority Having Jurisdiction. 1014.3.4.3 Access. Each gravity grease interceptor shall be located so as to be readily accessible to the equipment required for maintenance.

FOG disposal systems shall pro- duce an effluent quality not to exceed 5.84 grains per gallon (gr/gal) (100 mg/L) FOG in accordance with ASME A112.14.6. 1016.0 Sand Interceptors. A sand interceptor is a device designed and installed to separate and retain deleterious, hazardous or undesirable matter from normal wastes and permit normal sewage or liquid wastes to discharge into the sewer by gravity (see Figure 1016.0). The sand interceptor is often used in garage or car wash installations to collect deposited sand before entry to the public sewer. Multiple floor drains are used and may drain to a single interceptor. The floor drains from these installations need not be trapped as they are not connected directly to the sanitary system and could become plugged with accumulated sand. 1016.1 Discharge. Where the discharge of a fixture or draM contain solids or semi -solids heavier than water that would be harmful to a drainage system or cause a stoppage within the system, the discharge shall be through a sand interceptor. Multiple floor drains shall be permitted to dis- arge into one sand interceptor. .16.2 Authority Having Jurisdiction.

Based on 30-minute retention time (ref.: George Tchobanoglous and Metcalf & Eddy. Wastewater Engineering Treatment, Disposal and Reuse, 3rd Ed. 1991 & Ronald Crites and George Tchobanoglous. Small and Decentralized Wastewater Management Systems, 1998). Rounded up to nominal interceptor volume. 3 Where the flow rate of directly connected fixture(s) or appliance(s) have no assigned DFU values, the additional grease interceptor volume shall be based on the known flow rate (gpm) (L/s) multiplied by 30 minutes. EXAMPLE 1014.3.6 GRAVITY GREASE INTERCEPTOR SIZING EXAMPLE Given: A restaurant with the following fixtures and equip- ment. One food preparation sink; three floor drains - one in the food prep area, one in the grill area, and one receiving the indirect waste from the ice machine and a mop sink. Kitchen DraM Line DFU Count (from Table 702.1): 3 floor drains at 2 DFUs each 6 DFUs Mop sink at 3 DFUs each = 3 DFUs Food prep sink at 3 DFUs each = 3 DFUs Total = 12 DFUs Using Table 1014.3.6, the grease interceptor will be sized at 750 gallons (2389 L). tors are required where the Authority Having Jurisdiction deems it advisable to have a sand interceptor to protect the drainage system. 2015 UNIFORM PLUMBING CODE ILLUSTRATED TRAINING MANUAL 319 TRAPS AND INTERCEPTORS Plan _ Cleanout 77.-T All fittings are 4" CI pipe. _J Steel frame and plates for this interceptor are supplied separately.

Sand interceptors shall be built of brick or concrete, prefabricated coated steel, or other watertight material. The interceptor shall have an interior baffle for full separation of the interceptor into two sections. The outlet pipe shall be the same size as the inlet pipe of the sand interceptor, the minimum being 3 inches (80 mm), and the baffle shall have two openings of the same diameter as the outlet pipe and at the same invert as the outlet pipe. These openings shall be staggered so that there cannot be a straight line flow between the inlet pipe and the outlet pipe. The invert of the inlet pipe shall be no lower than the invert of the outlet pipe. The sand interceptor shall have a minimum dimension of 2 square feet (0.2 m2) for the net free opening of the inlet section and a minimum depth under the invert of the outlet pipe of 2 feet (610 mm). For each 5 gpm (0.3 L/s) flow or fraction thereof over 20 gpm (1.26 L/s), the area of the sand interceptor inlet sec- tion is to be increased by 1 square foot (0.09 m2). The out- let section shall at all times have a minimum area of 50 per- cent of the inlet section. The outlet section shall be covered by a solid remov- able cover, set flush with the finished floor, and the inlet section shall have an open grating, set flush with the fin- ished floor and suitable for the traffic in the area in which it is located. 1016.4 Separate Use. Sand and similar interceptors for every solid shall be so designed and located as to be readily accessible for cleaning, shall have a water seal of not less than 6 inches (152 mm), and shall be vented. ransyerse Section 1017.0 Oil and Flammable Liquid Interceptors. ms=11, The oil separator provides for the separation and removal of oil or flammable liquids. See Figure 1017.0 for an illustration of this interceptor. 1017.1 Interceptors Required. Repair garages anu gasoline stations with grease racks or grease pits, and facto- ries that have oily, flammable, or both types of wastes as a result of manufacturing, storage, maintenance, repair, or testing processes, shall be provided with an oil or flammable liquid interceptor that shall be connected to nec- essary floor drains. The separation or vapor compartment shall be independently vented to the outer air. Where two or more separation or vapor compartments are used, each shall be vented to the outer air or shall be permitted to connect to a header that is installed at a minimum of 6 inches (152 mm) above the spill line of the lowest floor draM and vent- ed independently to the outer air. The minimum size of a flammable vapor vent shall be not less than 2 inches (50 mm), and, where vented through a sidewall, the vent shall be not less than 10 feet (3048 nun) above the adjacent level at an approved location. The interceptor shall be vented on the sewer side and shall not connect to a flammable vapor vent. Oil and flammable interceptors shall be provided with gastight cleanout covers that shall be readily accessible. The waste line shall be not less than 3 inches (80 mm) in diameter with a full-size cleanout to grade. Where an inter- ceptor is provided with an overflow, it shall be provided with an overflow line [not less than 2 inches (50 mm) iri diameter] to an approved waste oil tank having a minimum capacity of 550 gallons (2082 L) and meeting the requir ments of the Authority Having Jurisdiction.
