American Standard manual flush valves are designed to meet the demands of high-use space with labor-saving installation, water-saving operation, and time-saving maintenance and care. This 1.28 gpf manual flush valve has a self-cleaning brass piston with integral wiper spring to prevent clogging and reduce maintenance. The piston valve remains closed and does not need to be reset after loss of water pressure. Features a non-hold open handle, chloramine-resistant EPDM seals, and an adjustable tailpiece for rough-in flexibility. Requires no external volume adjustment. Includes a 1" IPS angle stop with backflow prevention and a vandal-resistant cap, a sweat solder kit with a cover tube and wall flange, a high-back pressure vacuum breaker with down tube, and a spud coupling and flange for a 1-1/2" top spud. For use with 1-1/2" top spud wall-hung or floor-mounted toilet bowls.
