Complete with a high-performance fill valve designed to fit 99% of toilets and an adjustable, longest lasting 2 in toilet valve flapper, the Korky QUIETFILL platinum fill valve and 2 in flapper kit is designed to fix the two most commonly replaced parts in a toilet. Easy-to-install, the toilet fill valve is designed to fix no/slow refilling, running and noisy toilets. Quieter than other fill valves, the QUIETFILL platinum valve is ideal for toilets since 1994 (1.6 gpf or less). It is fully adjustable to prevent water waste in all toilets. The refill adjuster delivers the right amount of water to the bowl to maintain original performance. This toilet fill valve is easy to install and adjust, no tools are required. Designed to fit more toilets, the Korky toilet fill valve adjusts from 7-3/4 to 13-1/2 in.
