Gerber Danze G0099788 Flapper (Soft) 1.28gpf 3 Diameter for Avalanche (all model years) Viper Brianne Allerton Logan Square Wicker Park 28-970/980 & PeeWee HE-20-601, Brushed Nickel

I wasn’t able to remove the old flapper, but my plumber said this was the correct model & he was able to install it.

Hard to find and was exactly what we needed

I had a slowly leaking toilet flapper (toilet would refill for a few seconds once per hour or so). I thought, Ill just grab a replacement flapper from the hardware store or buy the cheapest one from Amazon. But, while searching Amazon, I read a lot of negative reviews where folks said that their new flapper didnt fit properly. I realized that you have to sometimes get a very specific, exact match as a replacement. I looked at the toilet bowl and it said Gerber 1.28 gpf (gallons-per-flush). Thats the first clue. Then inside the tank was printed, Replace Flapper with 99-788. So a quick Amazon search for Gerber 1.28 gpf 99-788 Flapper, and here we are. It was very easy to remove the old flapper and install this new one. 1) turn the water off and flush the toilet to drain the water from the tank. 2) unhook the old flappers rubber tabs and chain, and remove. 3) adjust the chain on the new flapper to match the length of the old chain. 4) connect the new flappers rubber tabs and chain into the tank. 5) turn the water back on. 6) after the tank fills, flush to make sure the chain is adjusted properly and the new flapper seats correctly and doesnt leak. This is a high-quality, thick, soft rubber flapper which seems to be doing a great job (no more leaking). I cant speak for longevity as its only been in use for a few days now.

Fits as expected.

Worked as advertised.

Great product. Prompt delivery.

Wish these had a longer life. Tried a Korky replacement because they seem to last longer, but the Korky feels squishy when you flush compared to these factory originals.

It was not as easy to install as others I have done, but I am getting older so more things are harder to do!

Does not fir the Gerber listed.
