Complete with a high-performance fill valve designed to fit 99% of toilets and an adjustable, longest-lasting 3 in flapper, the Korky QuietFILL platinum fill valve and 3 in flapper kit is designed to fix the two most commonly replaced parts in a toilet. Easy-to-install, the 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). 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. The universal flapper is designed to replace the majority of 3 in flappers. The kit is designed to fit Kohler, TOTO, American Standard and all other brands.
