How to Check for a Toilet Leak

Did you know that the average household leaks can account for more than 10,000 gallons of water wasted every year? That’s enough water for 270 loads of laundry! Fortunately, checking for toilet leaks is quick and easy. Find how to check your toilet for leaks and what to do if you find one below.

How Do You Check for Toilet Leaks?

Remove the toilet tank lid from the back of your toilet.

Drop a few drops of food coloring directly into your toilet tank.

Put the lid back on and let the food coloring sit. Don’t flush! Leave the room and come back 15 minutes later.

Check the toilet bowl. If the colored water now appears in the bowl, it leaked from the tank into the bowl and you have a leak.

What Should You Do If You Have a Leak?

If you find that you do have a toilet leak, you will want to inspect the float and inlet valve in your tank. If this mechanism isn’t working properly, the water will seep into your toilet bowl even when you haven’t flushed.

  1. Check the valve flushing the toilet and lifting the rod that holds the float. If the water stops, your inlet valve is working properly.
  2. Adjust your float by so that it sits at the proper level in your tank. You may also need to replace the float if it is damaged.
  3. Test the flapper. If the flapper has a leak, you may need to replace this part of your toilet.
