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

Quick service from the provider. This is one item that only the OEM part works correctly.

Exactly what I needed

Great quality. Easy install.

Its been a few days, product works as it should. Toilets no longer running. But the real question is, how long will it last.

I tried a few others and had to return them. This is the ONLY one that works for the oversized Gerber commode opening.

Easy peasy install

Lasted 8 months before warping. I purchased again since I needed one quickly but will be looking for a different option for next time.

Great fit

I have three Gerber toilets that were installed less than 2 years ago and the flappers (G0099788) that were supplied with the toilets have all gone bad. Prior to this, we had 12 year old toilets that we only had to replace the flappers twice for leakage (I keep track). I dont know if its the material that Gerber uses to make these flappers, but its disappointing. If you can find 3 flappers elsewhere, do it.

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.
