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. A worn or damaged toilet flush valve seal can cause running toilets, weak flushes, and hard-to-flush toilets. Replacing the seal is simple and usually only needed every few years.

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 valve. All you need to do is identify the flush valve inside your tank. Match the flush valve in your toilet to the images below, and you will go straight to the correct replacement part for a quick, reliable fix.
