Designed to minimize costly water loss, the fill valve is the only dual shut-off fill valve that detects toilet flapper leaks and hang-ups. Saves water due to leaks by not refilling the tank during a slow toilet flapper valve leak and automatically shuts off if flapper is stuck open. Designed to fit more toilets, this toilet fill valve adjusts from 7-3/4 to 13-1/2 in, fitting large and small tanks. The fill valve is proven quieter than other fill valves. Easy-to-install, the 528Z toilet parts include – (one) 528z toilet fill valve, (one) refill tube, (one) metal refill tube clip, (one) mounting nut, (one) cone washer, (one) coupling nut, (one) tamper proof key and (one) instructions.
