A new line of commercial hands-free, dual-flush toilet valves from American Standard automatically adjust flush volume, thereby consuming 20 percent less water than standard toilets. The Selectronic dual-flush toilet valve releases a light flush, or 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 Selectronic line simplifies specification and installation while reducing maintenance time.
