K835-97 Water Saving Repair Kit, Plastic

This Flush all high performance flush valve converts a poor performing toilet into a high performance toilet. It is easy-to-install in most standard toilets with a 2 in. flush valve. The 3 in. flapper opening funnels down to a standard 2-in. outlet, creating a vortex and increasing the flushing power of a standard toilet by 40 percent while saving 2,500 gallons of water annually.
