A new line of hands-free, dual-flush toilet valves from American Standard automatically adjusts flush volume, reportedly consuming 20 percent less water thanstandard toilets. The Selectronic dual-flush toilet valve releases a light flush, or 1.1 gallons per flush (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 sensor’s range comes preset and can be adjusted either manually or via remote control. www.americanstandard.com
