Review on High Performance 2 Pack Toilet Flapper Replacement by Hibbent - Easy to Install, Gerber 99-788 Compatible - Blue Color by Justin Cage

It was difficult to find a damper that would fit my Gerber toilet which was marked as damper #A700895-GEG1. This valve fit and worked perfectly. The second toilet, which was installed at the same time as the first, also needed a damper replacement. With the last one, I can't estimate how long the originals lasted 4 years in the toilet before small amounts ran into the bowl and filled with water again. Tank from time to time when not in use.
