Sloan’s dual-flush, side-mount, battery-powered retrofit flushometer product installs onto existing manual flush valves. Indicator lights show when the user is in range or if batteries are low. The unit’s Smart Sense technology automatically initiates a reduced 1.1-gpf output when the restroom user is in range for less than 60 seconds. If users prefer to flush manually, they can choose the appropriate flush cycle by pushing one of two buttons: the black button for 1.6 gpf or the green button for a 1.1-gpf cycle.
