Installation Tips

To install your new toilet flapper:

1. Close the water valve leading to the toilet
2. Drain the water from the tank
3. Remove the old leaking flapper (if hard to remove, cut it rather than pulling forcibly)
4. Install the new toilet flapper and attach the chain

Note: When you open the package, there may be an odor which will dissipate after the flapper has been exposed to air for a period of time.
