Dealing With A Toilet Tank Gasket Leak

Your toilet can leak for a number of reasons––and a leaking gasket may be one of them. It’s smart to check your toilet’s gasket when you’re dealing with a leaking toilet.

Check Your Toilet Tank Gasket

The gasket in your toilet tank is essential for your toilet to work properly by allowing water to refill the bowl each time the toilet is flushed. However, like most parts of your plumbing system, your toilet tank gasket can wear down over time and start leaking. When that happens, you’ll notice water droplets only after flushing, because that’s when water comes in contact with the gasket.

How to check for toilet tank gasket leaks

  • Dry off the toilet tank, toilet bowl, and the floor around it so that you'll be able to see new leaks.

  • Look between the tank and the bowl with a flashlight, then flush the toilet. Watch for leaking water. If you can't see any water, feel the back of the bowl for wet spots. If water only leaks out when you flush the toilet, then it's the tank to bowl gasket.

If a leaking gasket isn’t the issue, consider other causes of water leaks at the base of the toilet.
