How can I check for a leaky toilet?
Adding food coloring to the tank is one way of checking. If you have a leak, the food coloring will spread into the bowl, causing it to change color as well. The most common causes of a leaking toilet are:
  • The float device set too high, which causes water to run into the overflow tube
  • A warped or cracked flapper
