What Flush Valve Seal Do I Need?

If you have a tower-style flush valve (the tall canister in the center of the tank) it's seal can wear out over time. These toilets use a flush valve seal instead of a traditional flapper to help keep water in the tank. A worn or damaged toilet flush valve seal can cause running toilets, weak flushes, and hard-to-flush toilets.

Korky makes it easy to find the right seal for your toilet model. Most of the time, there is no need to replace the full flush valve. Simply identify the flush valve inside your tank and match it to the images below to find the correct replacement seal.

Replacing the seal is simple and usually only needed every few years. You can browse all Korky flush valve seals and flappers if you already know which replacement you need.
