Review: Does the job easily and cheaply - Used in Kohler toilets to replace failing flappers. Super easy to swap in and they work perfectly. Cheap and easy solution to running toilets. I always keep an extra around, so the multipack is nice to have. Zero running after you replace them and I have yet to need to replace one of these.
Review: simple and easy replacement flapper - Great replacement for an old, worn out flapper that was just stiff and not sealing anymore. Simple to install, fits well, works great!

## 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).
