What Customers Are Saying

Many customers report successful repairs using genuine replacement seals, with improved fit and material quality compared to aftermarket alternatives. However, a significant portion experience recurring leaks or phantom flushing despite replacements, with some reporting failures within weeks or months. Several note the issue stems from fundamental flush valve design rather than seal quality alone. While some find temporary success, the pattern of repeated failures has led many to distrust the brand and consider switching to alternative products entirely.

No more random flushes!

Quick delivery. Stopped the slow leak at the flush seal &, more so, stopped the phantom toilet flushes! :)

HELP!!!

Zero stars! What a waste of money and water! All 3 toilets are still self-flushing, 2 every minute 24/7. Does American Standard have a way of stopping this water waste, or do we have to replace our toilets with other brands?

Champion Seal Kit

American Standard seems to be the only seal kit that works--all the others leak immediately or soon thereafter

Repair kit improved over original.

Works as expected. Seal more pliable than original. Hopefully will last. Easy to install.

Toilet filling up about every hour

Ordered parts for “ghost flushing” and it’s still happening. Read reviews that said this was the fix and toilet is only two years old. Don’t know what’s wrong or what else to do.

Solved toilet leak issue

Saw YouTube post on cause of this type of toilet leaking/running. Recommendation was to use American Standard seal vs big box store brand. Web search found AS site and ordering was straightforward and arrived within 5 days. Replacement was easy but needed wrench to get better grip on top screw to remove. Needed to reseat top/bottom after a day since still leaked; needed to align top/bottom better. Once did that , good as new after two weeks.

This time OEM is better and cheaper

Works better than no name replacements (I went through two in the past three years). Extra parts included so toilet flushes quickly and quietly. Diagram tiny but in English and very helpful. Time will tell.

Not happy!!

I'm not happy with having to buy a seal for my new toilet that I paid nearly $300 to install in my bathroom.

Great toilet - good warranty follow up.

Champion 4 great toilet. Small problem with flush seals remedied. Followed through with their warranty. Solid company.

Replaced flapper seal

The kit with instructions made it easy to replace the seal.

Good, Bad, and Annoying

Toilets such as American Standard and Champion that are the best flushing have a seal mechanism that is poorly designed due to thin, poor quality seal. They need replacing fairly frequently due to their developing small blisters that result in increasing water dripping from the toilet bowl. Great toilets with a poorly designed, poor quality seal that is expensive.

So far so good.

So far so good. The after market seals are junk. This seal is working like it's suppose to.

Did the job

Works as intended. I hope that these are made better than the originals that came with the toilet as they did not last very long.

Easy Seal Replacement

This seal replacement did the trick in stopping ghost flushes on our toilets. Replacing it was easy but you need to make sure the slots on the dome line up perfectly or you won't solve the problem.
