Korky WaterWISE Toilet Fill Valve

Designed to minimize costly water loss, the WaterWI$E Fill Valve is the only dual shut-off fill valve that detects flapper leaks and hang-ups. Saves water due to leaks by not refilling the tank during a slow flapper leak and automatically shuts off if flapper is stuck open. Designed to fit more toilets, this toilet fill valve adjusts to fit both large and compact toilet tanks. The WaterWI$E Fill Valve is proven quieter than other fill valves.
