Easy to install. Works great. I'm not the best at plumbing, but i could tell right off that this would do the trick. Replaced my 10+ years' old one, installation is one minute work.

The only issue about these is the longevity. No more annoying leaky toilet sound. It's heavier than the brand it replaced and no more leaks.

All three toilets have a constant slow trickle. Leaking already. After one push of the flush handle, korky is back down.

The warranty requires sending the * deteriorated ones back to the company in order to get replacements. This year, however, was not the case. The korky's the culprit.

Simple-minded flapper is a knock off a cheap scam. This universal korky did not fit at the pivot points.
