CHAPTER 10 TRAPS, INTERCEPTORS AND …

1 CHAPTER 10 TRAPS, INTERCEPTORS AND SEPARATORSSECTION CHAPTER shall govern the material andinstallation of traps, INTERCEPTORS and 1002 TRAP Fixture plumbing fixture shall be sepa-rately trapped by a liquid-seal trap, except as otherwise permit-ted by this code. The vertical distance from the fixture outlet tothe trap weir shall not exceed 24 inches (610 mm), and the hori-zontal distance shall not exceed 30 inches (610 mm) measuredfrom the centerline of the fixture outlet to the centerline of theinlet of the trap. The height of a clothes washer standpipe abovea trap shall conform to Section A fixture shall not bedouble :1.

2 This section shall not apply to fixtures with A combination plumbing fixture is permitted to beinstalled on one trap, provided that one compartmentis not more than 6 inches (152 mm) deeper than theother compartment and the waste outlets are not morethan 30 inches (762 mm) A grease interceptor intended to serve as a fixture trapin accordance with the manufacturer s installationinstructions shall be permitted to serve as the trap for asingle fixture or a combination sink of not more thanthree compartments where the vertical distance fromthe fixture outlet to the inlet of the interceptor does notexceed 30 inches (762 mm) and thedeveloped lengthof the waste pipe from the most upstream fixture out-let to the inlet of the interceptor does not exceed 60inches (1524 mm).

3 Design of traps shall be traps shall not have interior partitions, except wheresuch traps are integral with the fixture or where such traps areconstructed of anapprovedmaterial that is resistant to corro-sion and degradation. Slip joints shall be made with anapprovedelastomeric gasket and shall be installed only on thetrap inlet, trap outlet and within the trap Prohibited following types of traps are pro-hibited:1. Traps that depend on moving parts to maintain the Bell Crown-vented Traps not integral with a fixture and that depend on inte-rior partitions for the seal, except those traps constructedof anapprovedmaterial that is resistant to corrosion S Drum :Drum traps used as solids interceptorsand drum traps serving chemical waste systems shallnot be Trap fixture trap shall have a liquid seal ofnot less than 2 inches (51 mm) and not more than 4 inches (102mm), or deeper for special designs relating to accessible fix-tures.

4 Where a trap seal is subject to loss by evaporation, a trapseal primer valve shall be installed. Trap seal primer valvesshall connect to the trap at a point above the level of the trapseal. A trap seal primer valve shall conform to ASSE 1018 orASSE Size of fixture trap size shall be suffi-cient to drain the fixture rapidly and not less than the size indi-cated in Table A trap shall not be larger than the drainagepipe into which the trap Building (house) traps shall be prohib-ited, except where local conditions necessitate such traps shall be provided with a cleanout and a reliefvent or fresh air intake on the inlet side of the trap.

5 The size ofthe relief vent or fresh air intake shall not be less than one-halfthe diameter of the drain to which the relief vent or air intakeconnects. Such relief vent or fresh air intake shall be carriedabove grade and shall be terminated in a screened outlet locatedoutside the Trap setting and shall be set levelwith respect to the trap seal and, where necessary, shall be pro-tected from Recess for trap recess provided for con-nection of the underground trap, such as one serving a bathtubin slab-type construction, shall have sides and a bottom of cor-rosion-resistant, insect- and verminproof Acid-resisting a vitrified clay or otherbrittleware, acid-resisting trap is installed underground.

6 Suchtrap shall be embedded in concrete extending 6 inches (152mm) beyond the bottom and sides of the Plumbing in mental health mental healthcenters, pipes and traps shall not be 1003 INTERCEPTORS AND Where and separators shall beprovided to prevent the discharge of oil, grease, sand and othersubstances harmful or hazardous to the building drainage sys-tem, thepublic sewer,the private sewage disposal system or thesewage treatment plant or FLORIDA BUILDING CODE size, type and location of each intercep-tor and of each separator shall be approved by the plumbingofficial. Where the interceptor or separator is located within anonsite sewage treatment and disposal system, such interceptoror separator shall be approved by the health official.

7 The inter-ceptor or separator shall be designed and installed in accor-dance with the manufacturer s instructions and therequirements of this section. Wastes that do not require treat-ment or separation shall not be discharged into any interceptoror Grease traps and grease INTERCEPTORS for publiclyowned or investor-owned sewage intercep-tors shall comply with the requirements of Sections Grease INTERCEPTORS and automatic greaseremoval devices grease interceptor or auto-matic grease removal device shall be required to receive thedrainage from fixtures and equipment with grease-ladenwaste located in food preparation areas, such as in restau-rants, hotel kitchens, hospitals, school kitchens, bars, fac-tory cafeterias and clubs.

8 Fixtures and equipment shallinclude pot sinks, prerinse sinks; soup kettles or similardevices; wok stations; floor drains or sinks into which ket-tles are drained; automatic hood wash units and dishwasherswithout prerinse sinks. Grease INTERCEPTORS and automaticgrease removal devices shall receive waste only from fix-tures and equipment that allow fats, oils or grease to be Food waste food waste grindersconnect to grease INTERCEPTORS , a solids interceptor shall sep-arate the discharge before connecting to the grease intercep-tor. Solids INTERCEPTORS and grease INTERCEPTORS shall be sizedand rated for the discharge of the food waste grinder.

9 Emul-sifiers, chemicals, enzymes and bacteria shall not dischargeinto the food waste Grease INTERCEPTORS and automatic greaseremoval devices not grease interceptor or anautomatic grease removal device shall not be required forindividual dwelling units or any private living Grease INTERCEPTORS and automatic greaseremoval INTERCEPTORS and automatic greaseremoval devices shall be sized in accordance with PDIG101, ASME Appendix A, or Grease INTERCEPTORS and automatic greaseremoval devices shall be designed and tested in accordancewith PDI G101, ASME or ASME INTERCEPTORS and automatic grease removal devicesshall be installed in accordance with the manufacturer.

10 Grease INTERCEPTORS that are sized, con-structed and approved in accordance with Rule 64E-6,Florida Administrative Codeand that are located outsidethe building shall not be required to meet the require-ments of this Grease interceptor inter-ceptors and grease traps shall have the grease retentioncapacity indicated in Table for theflow-through rates Rate of flow interceptorsand grease traps shall be equipped with devices to controlthe rate of water flow so that the water flow does notexceed the rated flow. The flow-control device shall bevented and terminate not less than 6 inches (152 mm)above the flood rim level or be installed in accordancewith the manufacturer s Automatic grease removal auto-matic grease removal devices are installed, such devicesshall be located downstream of each fixture or multiple fix-tures in accordance with the manufacturer s automatic grease removal device shall be sized topretreat the measured or calculated flows for all connectedfixtures or equipment.
