Will save you money

Had issues with toilet double flushing, Google recommended this flapper. Easy install. I tried same brand but with out the level wheel thing they didnt fix the issue. This one Fixed the problem. Only wish did it sooner. Adjusting was alittle tricky . Nice seal. I like that you can flush 2x if you want with this thing, But it also will save you money bc you can flush with a little amount of water or a lot.

Excellent fit, stopped the water leak

We have a water saver toilet, and the flapper has aged enough that it leaks and the float has started not working properly. We got a new universal float and flapper set, the float worked fine, but the flapper wouldn't fix this toilet, so, it still leaked. We purchased this flapper, installed it in minutes and haven't had a leak since.

This works as intended and is adjustable so the amount of water used is to your liking. Easy to install, I did it myself.
