Stop the loss of water. The seal is excellent.

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.

DIY Relace 3-inch Toilet Flapper

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.

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.
