American Standard Selectronic Ultima Concealed Toilet Flush Valve with Wall Box (Base Model) - 1.1 GPF - 606B312.007

The American Standard Selectronic Ultima concealed toilet flush valve (606B312.007) delivers hygienic, hands-free performance for commercial restroom installations. Built for wall-hung flushometer bowls with a 1-1/2" back spud, this piston-type valve provides a 1.1 GPF (4.2 LPF) flush volume to help reduce water use without compromising performance. The Selectronic proximity sensor supports touchless activation, while state-of-the-art electronics help prevent ghost flushing. A self-cleaning piston with an integral wiper spring reduces clogging and maintenance, and chemical-resistant EPDM seals extend service life. The system includes a vandal-resistant stainless steel wall box with front access and a fully mechanical manual override button that can flush without power. It also features fail-safe operation (closes upon loss of power or water pressure), an adjustable sanitary flush to help maintain trap seal, and an adjustable tailpiece for rough-in flexibility. Can be installed left- or right-handed. Included components: 1" I.P.S. angle stop with back-flow protection and handwheel; 1" sweat solder adapter; 1-1/2" vacuum breaker with spud coupling and flange. Power supply/kit is required and must be purchased separately.
