ASME A112.19.2:2003 pdf free download Vitreous China Plumbing Fixtures and Hydraulic Requirements for Water Closets and Urinals
3.9 Urinals
3.9.1 Trapway Urinals shall have a trapway which shall pass a 3 ⁄ 4 in. (19 mm) minimum diameter ball, except where larger diameters are specified for certain urinal types in Table 3.
3.9.2 Urinal Sizes. Minimum urinal dimensions shall be as specified in Table 4.
3.10 Drinking Fountains Drinking fountains shall have an integral bowl with beveled or rounded corners or edges and be designed for minimal splashing of water. Fixtures shall be permit- ted to have integral strainers. The nozzle head base shall be above the level of the overflow point of the bowl rim. Drinking fountain fittings shall comply with the applicable requirements of ASME A112.18.1 and ARI 1010. 3.11 Bidets
3.11.1 Bidet Sizes. Bidets shall have a rim height of 14 to 16 in. (356 to 406 mm) and a variable rough-in based upon the fitting used.
3.11.2 Bidet Punchings. Bidets shall be configured to allow the installation of either wall- or deck-mounted bidet fittings. When fittings are not provided with the fixture, bidet supply and outlet punchings shall comply with Fig. 6.
3.11.3 Bidet Flood Levels. Bidets, relying on an airgap for backflow protection, shall have a flood level not more than 1 ⁄ 2 in. (13 mm) above the lowest point of the faucet bearing.
4 FLUSHING DEVICES
4.1 Requirements for Flushing Devices All flushing devices shall deliver water at a sufficient rate and quantity to permit the fixture to meet the per- formance requirements of this Standard. Gravity flush 8 tanks, pressurized flushing devices, and other flushing methods shall be permitted. Air gaps, vacuum breakers, and other backflow preventers shall be installed above the overflow or flood level of the fixture or device, or spill openings to the outside of the flush tank shall be provided as required in para. 4.2.
4.2 Gravity Flush Tanks Trimmed gravity flush tanks for water closets and urinals shall include an antisiphon fill valve complying with ASSE 1002. Each tank shall have provisions for overflow. The critical level (C/L) mark on the fill valve shall be 1 in. (25 mm) minimum above the overflow in the tank. Water closet flush tank punchings shall con- form to the dimensions shown in Fig. 7. Where the critical level of the fill valve in low-profile tank water closets is below the flood level of the rim, auxiliary spill openings shall be provided so that the water in the tank will exit to the floor if the overflow is clogged or the trap is blocked. The size and position of these openings shall be such that with the fill valve at the full open position and the water pressure at code maximum, no water shall rise to the critical level of the fill valve.
4.3 Pressurized Flushing Devices Pressurized flushing devices shall comply with ASSE 1037. The critical level (C/L) of the lowest antisiphon device within a flushometer-tank activated water closet shall be 1 in. (25 mm) minimum above the flood level of the water closet rim. Where the critical level of the pressurized flushing device in low-profile tank water closets is below the flood level of the rim, auxiliary spill openings shall be provided so that the water in the tank will exit to the floor if the overflow is clogged or the trap is blocked. The size and position of these openings shall be such thatwiththe fillvalve forthepressurizedflushingdevice at the full open position and the water pressure at code maximum, no water shall rise to the critical level of the pressurized flushing device.
4.4 Plastic Water Closet Tanks Plastic water closet tanks intended for use with vitre- ous china bowls shall comply with the requirements of ANSI Z124.4.
5 PERFORMANCE REQUIREMENTS The purpose of this paragraph is to define hydraulic performance tests for water closets, urinals, and lavato- ries that discharge into gravity waste systems in perma- nent buildings and structures. The test protocols in para. 8 shall be followed to determine compliance to this Standard.
