How to Check for Toilet Bowl Leaks

Earth Day is just a few days away and it’s time to start thinking about how you can make your home a little bit more eco-friendly. One simple way to conserve water at home is by checking your toilet bowl for leaks. Although you may not notice any visible changes in your toilet plumbing, water leaks account for almost 14% of all water use in the average home!

Fortunately, with a quick 15-minute check, you can take a look and see if your toilet bowl has any leaks this weekend. It’s the perfect way to help protect the environment, your wallet, and your home plumbing.

How to Check for Toilet Bowl Leaks:

  1. Put 5-10 drops of food coloring in the back toilet tank.

  2. Wait 15 minutes.

  3. Check the toilet bowl (not the tank) — if you see food coloring in the bowl, you know that you have a leak in between the tank and the bowl.
