In this guide, we’ll walk you through the steps of replacing a toilet tank gasket. We’ll provide detailed instructions, along with photos and diagrams to help you along the way. By the end of this guide, you’ll be able to replace your toilet tank gasket like a pro!

What You’ll Need

To replace your toilet tank gasket, you’ll need the following materials:

• New toilet tank gasket
• Replacement wax ring (optional)
• Penetrating oil
• Adjustable wrench
• Pliers
• Flathead screwdriver
• Bucket
• Sponge
• Paper towels

Steps

1. Turn off the water supply to the toilet. Locate the shut-off valve under the sink or behind the toilet. Turn the valve clockwise until it is completely closed.
2. Flush the toilet to drain the water from the tank.
3. Remove the old gasket. The gasket is located at the bottom of the toilet tank, where the tank meets the bowl. It is a thin, rubber ring that is held in place by a metal clip. To remove the gasket, use a flathead screwdriver to pry up the metal clip. Then, carefully remove the gasket.
4. Apply penetrating oil to the threads of the bolts that hold the toilet tank to the bowl. This will help to loosen the bolts and make them easier to remove.
5. Use an adjustable wrench to loosen and remove the bolts that hold the toilet tank to the bowl. There are usually two bolts, one on each side of the tank.
6. Carefully lift the toilet tank off of the bowl. There may be some water left in the tank, so be careful not to spill it.
7. Inspect the toilet bowl for any damage. If the bowl is cracked or damaged, it will need to be replaced before you can install the new gasket.
8. Apply a thin coat of plumber’s putty to the bottom of the new gasket. This will help to create a watertight seal.
9. Place the new gasket on the bottom of the toilet tank. Make sure that the gasket is centered and that the plumber’s putty is evenly distributed.
10. Reinstall the toilet tank on the bowl. Make sure that the bolts are tightened securely.
11. Turn the water supply back on to the toilet.
12. Flush the toilet to test the new gasket. The toilet should fill and drain normally without any leaks.
