KOHLER K-40TH00N10-RF Mach Wave Touchless retrofit toilet flushometer, HES-powered, 1.28 gpf

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.
