Why Replace Your Flush Valve Seal?

The flush valve seal is the workhorse of your toilet’s flush system. On older Champion models, the 738651-0070A seal degrades over time from chlorine, hard water minerals, and repeated use. A worn seal allows water to leak past the valve seat continuously, causing your toilet to run and wasting gallons of water daily. Replacing it is a quick, affordable fix that pays for itself fast.

Compatibility

Designed for older American Standard Champion toilets with the old style flush valve assembly. Verify your toilet model and flush valve style before ordering to confirm compatibility with the 738651-0070A seal.
