Best for use in 1.28, 1.6 and 3.5 GPF toilets. The 555C is a flapper and drain repair kit. The kit allows you to repair a damaged flush valve “drain seat” so that your new flapper can make a water tight seal.

The included PerforMAX® 2” Adjustable Flapper, has an adjustable dial for a customized flush and water-savings. Other features include a solid frame flapper design to ensure a secure seal and eliminate twisting, and built-in Microban® technology to fight bacteria on the flapper itself.
