Fluidmaster® 5403P4 Universal Water Saving Long Life 3" Toilet Flapper

I am a woman with zero plumbing experience and was able to fix my constantly running toilet with this! All you have to do is turn off the water to flush it (usually at bottom of toilet by the wall) and then flush it to empty and change the bulb. The chain is completely adjustable so make sure it is tight enough to pull up to flush.

Excellent product. Even though I had trouble unhooking my previous toilet flapper, this was an easy install. I was able to adjust the flush to my liking, the seal is perfect, and I can say for certain that this flapper works way better than my previous one. Definitely recommend!

Everything about this was very good. It stopped the excess use of water draining from the toilet tank. The only thing I didn't like about it is that once you put it on it clicks into place and getting it off is not very easy. It is more expensive than the other flappers, but it seems to be an item that will last quite a bit longer than the others.

The flapper valve on my Toto toilet began leaking after about 6 years of use. The problem was caused by reduced rigidity of the rubber flapper valve. The Fluidmaster 5403 addresses this design issue by using a rigid plastic structure and a flexible gasket for more positive sealing. The adjustable attaching arms assure that the valve remains centered. The adjustable float allows you to regulate the amount of water used for flushing. This valve is a little more costly, however, it successfully solves a number of issues.

This was a replacement toilet flapper. I would suggest that anyone replacing this make sure you select the correct size toilet flapper. I didn't realize they come in various sizes, but I found the correct one for my toilet.

I expect the Fluidmaster Flapper to last well over ten years. In teh past 25 or more years, I can only recall one Fluidmaster part failing and it was well past its warranty period.

This was perfect replacement for the 540 flapper in my American Standard Saver stool. Original only lasted a little over a year.

I tried replacing the flapper with genuine Toto, but it still started leaking. It is hard to find a 3" flapper. True Value and Home Depot did not have them. The fluidmaster works!

I needed to replace all my Toilet Flapper and they are all different so Wal Mart saved the day by having every flapper I needed at a great price with quick delivery. The Fluidmaster 5403P4 Adjustable Water-Saving Long Life 3 inch Toilet Flapper was exactly what I was looking for as I like the brand.

It's so nice, I gave it 5 stars in spite of the quirk in my toilet I hadn't realized. Mansfield has a model toilet that requires its own brand special flapper that isn't near as good as this one and doesn't last as long and costs the same. What a disappointment! But I adjusted this one beyond it's "universal"ness, and it still works great. Got the Mansfield replacement flapper for this toilet only (the arms where the flapper attaches are sized differently on each side, one side much larger), but this one I was able to get to work anyway, and this one is made to last.
