555C - 2" Universal Flush Valve Repair Kit with Flapper

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 advantage of this kit is that it allows you to repair a damaged flush valve without removing the tank and stop the water loss through the drain and flapper.
