Fluidmaster 5403 3-Inch Water Saving Long Life Toilet Flapper

This toilet flapper valve is easy to install and works perfectly. I can't recommend it enough. You won't be disappointed.

Works well, easy install

Replaced in a Builders grade Gerber toilet. Two min. Swap out no adjustments needed but the chain.

This was not universal in terms of latching. I’m. Ot sure if that was my fault, so I’ll settle on saying it seems like it will work great if you know how to use it and just know toilets apparently vary in stupid ways. So double check. Honestly I think this taught be it was not the flapper causing the running, but it was a solid try from an uninformed person taking the term universal as I think we generally would. I didn’t even know there was a difference in the flapper connection vs the size of the plug. That I really thought was universal. I accept my failure and momentary defeat lol Not going to return this, because it works fine and seems great quality. I only give 4 stars due to the marketing of universal not seemingly being 100 percent accurate and that was why I ordered a more expensive version of other cheaper ones.

This worked perfect in my Project Source toilet.

Easy install, works great

Works like it’s supposed to, but I must let you know, I measured for the part I needed. I always question reviews from people who say a part doesn’t fit. I wonder, did they measure? Don’t take 5 minutes to rate something low because you didn’t take a minute to measure! It was simple to install, took all of a few minutes from start to finish, including draining the tank. I’ve had absolutely no issues with leakage since installing the Fluidmaster. It’s been installed about a month now.

Installation was simple and it worked great initially. After about a year, the hook tends to loosen and fall out of the pole it attaches to, which can prevent the flap from closing properly. This happened on all my bathrooms around the same time, so be aware it might not last long-term.
