This kit takes the guessing out of fixing your toilet, it comes with a universal flapper system that adheres to any toilet surface, metal, plastic and ceramic. The peel and stick design can repair and replace old flush valve drains without the need to remove the tank in minutes. The high performance fill valve with twice the refill power of a standard fill valve will refill the toilet bowl to the proper or optimum water level with every flush. The fill valve comes with a flow regulator that will quietly fill the tank without excessive water fill noise.

If you have a modern toilet that is wasting water, then replace the parts with this easy to use kit without removing the toilet tank. Best used with 2 piece (toilets with a removable tank) toilets. This kit works with all 2” toilets including Kohler®, Toto® and American Standard®, and more. This kit is not designed for 3″ flush valve toilets.
