Fluidmaster 510A-001-P10 American Standard and Eljer Replacement Flush Valve Seal, Blue

Great value for the money, easy to install, fits perfectly, quality rubber parts, seals great. I fit my American Standard toilet.

Easy yo install - fits my American Standard toilet perfectly - no more leaks.

Delivered quickly and works perfectly. Would buy again

Have the American Standard Champion 4. The toilet would keep refilling. After looking at it, the water in the tank would drain into the bowl until it dropped a couple of inches, then it would refill.I watched the one posted video review and followed the instructions. So easy, and just as the video said, the seal had bubbled up and it no longer held a tight seal.It took less than 5 minutes to replace.

Excellent price, very easy 5 minute intallation, solved the issue of hard to flush lever, sealed perfectly

Works for a short period of time. We have already needed to replace this ring a few times, but ultimately, it works fine until you hear running water again. Seal could use a little upgrade to ensure it fits better with the overall toilet unit. Slight leakage, but manageable.

Easy to install but seal only worked for 5 months before the material degraded forming a bubbled surfaces on both sides that allows slow leak problem to resume and I do not use an in tank toilet bowl cleaner that would cause this problem

Took just a few minutes to change. Stopped the leak. Low cost was also great
