Fluidmaster 5403 3-Inch Water Saving Long Life Toilet Flapper

Good price, works well, easy to install. Believe it or not at 85 I have just learned how to flush a low water toilet. Amazing.

package arrived open, not sure why but it could have definitely happened in shipping, I installed it and adjusted the chain and it seems to be working perfectly, if you have a fluidmaster 540 3 inch these will be a good replacement if needed, the quality of the flapper seems to be pretty good

Quick delivery, easy install.

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.

It fit and it works

My old toilet flapper had warped over time, and our toilet tank had started refilling almost constantly due to the failed seal. The rigid structure to the flapper means it won’t warp over time like the cheap rubber one that came with my toilet. It stopped the problem immediately upon installation. Installing and adjusting this new flapper is also MUCH easier than the old one, because the piece that fastens to the lever is a much more practical design. The “bulb” is really interesting as well; you can turn it to let in more or less water, which causes it to float longer or sink faster, thereby closing the drain slower or faster, depending on how much water you want to use or how strong of a flush you want. I chose to keep it all the way closed, so it stays full of air and floats on top of the water as it drains down. This causes almost the entire tank to drain before the flapper closes. I did test it with the bulb at different levels and it makes a BIG difference in how quick it closes and how much water gets used, but the toilet I was installing this on has issues flushing sometimes, so a stronger and more consistent flush is part of what I was looking for. Pros: • Works great • Won’t warp over time • Adjustable water-saving feature • Easy to install and adjust Cons: • A bit more expensive than some of the other options. I needed two new flappers, but chose to only buy one to make sure it worked. Despite it being more expensive, it was so easy to install and fixed my problem so immediately that I came back and bought the same one the next day.

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.
