Korky 818Z Fill Valve and Flapper Kit, Rubber Body, Black/Red, Anti-Siphon: Yes

Designed to minimize costly water loss, the WATERWISE 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 toilet 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 from 7-3/4 in to 13-1/2 in, fitting large and small tanks. The WATERWISE fill valve is quieter than other fill valves.
