Flushmate Genuine Replacement Parts

The Flushmate Flush Valve Cartridge is located in the center on the top of the Flushmate system.

This is the main valve that opens and closes to deliver the water to the toilet bowl.

This component is the same for all Flushmates since 1990.

If your Flush Valve Cartridge does not look like this, see the C-100100-KIT.
