If your toilet is leaky, noisy or continuously running, it is most likely an indication that the flapper is not sealing properly. To determine this, follow the simple food color test below.

Food color test
1. Remove tank cover and add drops of food coloring to toilet tank.
2. Wait 25 minutes.
3. If color appears in toilet bowl, the flapper is leaking (see problems below).

Problem: Flapper doesn’t seal properly on flush valve.
Solution: Confirm that the flapper and valve seating surfaces are clean and that the flapper is not malformed.
