Frequently Asked Questions

  • What is a toilet flapper?

    • A flapper valve is a type of valve used in flush toilets. It creates the watertight seal in the toilet tank that holds the water until flushing.

  • What size flapper do I need?

    • Fluidmaster manufactures 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 the 502 Adjustable Flapper work?

    • The 502 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.

  • Are all toilet flappers universal?

    • No. There are universal designs like the Fluidmaster flappers that replace most other flappers and there are specialty flappers for specific flushing systems.

  • How long should the chain be?

    • Fluidmaster recommends the chain to have 1/2” of slack from the lever to the top of the flapper.

  • Why is my flapper not closing?

    • If the flapper is not closing it could be that the flush valve is oversized and causing the flapper to stick. In these cases exchanging your flapper for an “all rubber” construction in place of a “solid frame construction” can resolve this issue.

  • How do I know if the flapper is the reason for the leak from my tank to the bowl?

    • Do a simple test, turn the water off to the toilet, leaving the tank full, and mark the tank water with a pencil. Come back and check the new level (repeat this process until the water does not drain any further) if the water drains to the lip of the flapper and no further then Fluidmaster recommends replacing the flapper.

  • Why does my toilet flapper drop so fast?

    • Modern toilets (from 1994 to current) are made to use less water from the tank to flush the bowl. In order to use less water the flapper valves are designed to close sooner whereas older toilets (1984 and past) are designed to use all the water and those flappers needed to stay open longer.

  • What is the float on the flapper chain for?

    • The float on the flapper chain is the adjustable component of the flapper and allows for the flapper to either stay open longer (for more water to be used for the flush) or to close sooner (for less water to be used for the flush).

  • Why do I have to hold my toilet handle down to get full flush?

    • Holding down the handle could mean the chain is set incorrectly (has too much slack) and resetting the chain so it has 1/2” of slack may solve the problem.

      If you’re using an adjustable flapper you may be using it on the wrong flapper setting. Try adjusting the setting to higher number so it stays open longer.

      If the toilet is from 1950-1984 and you are using the 502 Adjustable Flapper,  Fluidmaster recommends exchanging the flapper for a non-adjustable flapper like the Fluidmaster 501.
