How is the 555C Flush Valve Repair Kit different than other regular 2’” flappers?

The 555C Flusher Fixer Kit not only replaces the flapper valve but also replaces the drain seat of your flush valve. With a new drain seat and flapper you can update your flush valve without removing the tank to stop a leak. The 555C comes with both a drain seat replacement and a time adjustable flapper that you can use to control the amount of water that is flushed out of the tank. The 555C is also known as the no tank removal kit because it allows you to replace your drain and flapper without having to remove the toilet tank. This kit can be used on both 1 and 2 piece toilets.

How will I know which size of flapper will fit my toilet?

Fluidmaster manufactures both a universal 2” flapper and a universal 3” flapper. To determine the size of flapper you need, measure the drain hole the flapper covers, if the hole is 2.5 inches use a 2 inch flapper and if the drain hole is 3.5 inches use a 3 inch flapper.

How does an adjustable toilet flapper work?

An adjustable flapper can be turned like a dial and has numbers on it that range from minimum to a maximum setting. Turning the flapper to a lower number forces the flapper to close sooner for a shorter flush and setting it to a higher number will allow it to stay open longer for a longer flush.
