Toilet Flappers Replacement Compatible with Gerber 99-788, 2PCS High Performance Water Saving Blue Rubber Toilet Flapper Fits Most 3" Toilets Tank Valve, Easy to Install

My husband installed two in no time; very pleased!!

I can't yet rate "longevity" as it's only been in place for a little over a month, but so far, so good (they normally last years). I had bought a "universal" flapper and the toilet still leaked, so I went to Amazon for a "specific" model and this did the trick. Although it was easy to install, adjusting the length was a little harder, but we eventually got it right. I love that it's a 2-pack as I'm ready for the next leak; the 2-pack wasn't much more than the single replacement I had previously purchased locally - great value! I am happy we are no longer wasting water!

So far so good

I just saved a ton of money by fixing my leaky toilet with this device. Two years ago, I called a plumber to fix a similar problem on another toilet. They charged me almost $200 and just sat and played with my toilet for an hour or so. This time I just bought this item, changed it in less than 4 minutes and everything was back to normal again. I saved a lot of money and time and this works!

I didn't like that the picture implies that it's a set of 2 pieces.At the very end of the description it's written as being 1 piece.

Easy to install, working great!!

Kohler older tanks

With UTube aid, all’s well

Finally solved my leaky toilet problem

Bought this to replace Toto flapper that was no longer sealing. It's not hard to change a flapper but I had never changed one. Came with instructions. Took 1 minute to replace. Bought a two pack since all my toilets are Toto and now I have a spare!
