  • Works, easy to install

Accidentally bought a 2-in universal toilet replacement kit. I was able to use the rest of the kit but needed a replacement for the flapper - this did the trick. The end attachments are silicone or rubber - a bit stretchy so the fit my 20+ year old toilet. No more water leaks or high bills. This is a bit flexible, so I think it will last longer than the rigid rubber ones. ... show more

  • Perfect replacement for older toilet Perfect replacement for older toilet

The flapper in the toilet would not stop running, This flaper fixed it. The old flapper actually had to be cut off as it was old style integrated into the system. So happy to have found this silicone replacement where the holes expand to allow the flapper to be installed over tbe edges of the flapper bar. Staples the leak immediately. Easy economical fix without need to call a plumber. ... show more
