How to Fix a Leaking Toilet Seal

Fixing a leaking toilet seal is a relatively simple task that can be completed in a few minutes. Here are the steps involved:

1. Turn off the water supply to the toilet. To do this, locate the water supply valve located under the sink or behind the toilet. Turn the valve clockwise until it is completely closed.
2. Remove the toilet tank lid. To do this, locate the two bolts on the back of the toilet tank. Loosen the bolts with a screwdriver and then lift the lid off of the tank.
3. Inspect the toilet seal for damage. The toilet seal is located between the toilet bowl and the toilet tank. It is a rubber gasket that creates a seal to prevent water from leaking out of the tank. If the seal is damaged, it will need to be replaced.
4. Replace the toilet seal if it is damaged. To do this, remove the old seal by gently prying it up with a screwdriver. Then, apply a thin coat of plumber’s putty to the new seal and press it into place.
5. Reattach the toilet tank lid. Once the new seal is in place, reattach the toilet tank lid by tightening the two bolts.
6. Turn on the water supply to the toilet. Turn the water supply valve counterclockwise until it is fully open.

Once you have completed these steps, the leaking toilet seal should be fixed. If the leak persists, you may need to contact a plumber for assistance.

  • Fix any leaks around the toilet as soon as possible. If you notice a leak around the toilet, it is important to have it repaired or replaced as soon as possible. Leaks can waste water, create a mess, and be a health hazard.
