Korky 2X Long Life Toilet Flush Valve Seal Fits American Standard Champion 4 and Eljer Titan 4 - Fixes Leaking Flush Valves and Hard to Flush Toilets, 450BP

I have 3 -- Flush 4 toilets in the house. Within 3 years all of them started leaking.. The Blue colored seal in each of them had formed bubbles and were slightly deformed.. Put these Red ones in in place of all the blue ones.. They fit well and appear to be slightly better material and do say 5 year warranty. Time till tell but don't replace the blue ones with the blue ones. They will just fail again

There is a right way to install them. May have to reinstall (flip over gasket) if it continues to leak

fixed the drip all is good

I have an American Standard Champion 4 toilet. This thing is driving me crazy because the darn gasket periodically leaks. I first tried replacement with an off brand gasket, but that was a flop. I have purchased the American Standard part https://www.amazon.com/American-Standard-7301111-0070A-Flush-Valve/dp/B002J3SG0W/ but have been very disappointed that it starts leaking again within 6 months to a year. So I had high hopes for this Korky. But it failed right off the bat. I know how to install these (God knows that I get enough practice), but the toilet kept leaking intermittently with the brand new Korky gasket. So, back to the American Standard part. Fortunately I had purchased a spare last time, so I put in the OEM part and the leak immediately stopped, at least for now. (But the leak in this toilet is like The Terminator. It will be back....)

Was tired of using the original seals that bubbled and caused a leak about once a year. Replaced seal on 3 toilets with this one and one toilet leaked because I did not get the small grooves lined up correctly before tightening back together. Once I took it apart again and carefully lined up the grooves it worked great. Hopefully will last longer than the original seals.

This seal was easy to install and solved my minor leak problem.

Nice product

Be careful where you buy one of these. The price varies considerably. The one that came with the toilet developed a leak due to water blisters formed between the two layers of material. Apparently, they are made of a top and bottom that is sealed together. The original, apparently, was not perfectly sealed and 12 inches of head pressure was enough to allow water to force itself between the layers and to lift the flush valve enough to make it leak. I have not had this one long enough to know if it is any better made than the original.

Excellent product and fit precisely! My toilet no longer self flushes! :D
