Mach® WAVE Touchless toilet flushometer, DC-powered, 1.6 gpf (40TD00R10-CP)
by Kohler
WAVE technology offers hygienic touchless operation on command. Activating only when a hand is waved directly over the flushometer, the sensor eliminates random flushing that can be frightening for children. And by removing false actuations, WAVE technology provides even greater water savings.
