The Selectronic dual flush toilet valve uses 1.1 gpf when motion is detected for less than 60 seconds. A standard 1.6 gpf volume is used when motion is detected for 60 seconds or longer. The watertight miniature sensor and wireless program controller works for all Selectronic fittings on faucets, flush valves, and urinals made by American Standard. The units also include self-cleaning pistons, chemical-resistant EPDM seals, and a retrofit model.
