Review: Easy fix - I took a chance these would fit and they did. Easy to install just replace old one and secure as shown and fixed the issue. Quick fix to an annoying issue . Sealed quickly was made of quality material MUCH better than what was on there.
Review: Fixed the problem. - Toilet required to hold down the handle to flush, looked up toilet model and tank number, This fit the gerber maxwell 1.6 gallon tank with a 2” inch flush valve. With a setting on the flapper to 5 and it now flushes perfectly and fills the bowl where it should be. Definitely a quick and easy install. Had to adjust the chain to fit the handle I have. Also easy, just measure the chain to the slot on your handle lever and move the clasp to that position. Great quality product, appears solidly built.

## Questions & Answers

**Q: The dial on the flapper: How does it work?**
A: Great question! There are several numbers located on the underside of the flapper near the band. By turning the dial to the higher numbers, it closes off the holes allowing the flapper to float longer (this cause more water to enter your toilet bowl. By turning the band to the lower numbers, the flapper takes on water and closes faster (flushing less water).
