How To Replace Bathtub Overflow Gasket?

A bathtub overflow gasket is a rubber or plastic ring that seals the overflow drain in your bathtub. It prevents water from backing up into the tub and flooding your bathroom. Over time, the gasket can become worn or damaged, which can allow water to leak out of the drain. If you notice water leaking from your bathtub overflow drain, it’s time to replace the gasket.

Replacing a bathtub overflow gasket is a relatively simple DIY project that can be completed in about 30 minutes. Here’s what you’ll need:

  • A new bathtub overflow gasket
  • A putty knife
  • A screwdriver
  • A utility knife
  • A bucket
  • A sponge
  • A pair of gloves

Step 1: Turn off the water supply to the bathtub.

The first step is to turn off the water supply to the bathtub. This will prevent any water from leaking out of the drain while you’re working. To do this, find the shut-off valve for the bathtub and turn it clockwise until it’s completely closed.

Step 2: Remove the old gasket.

Once the water supply is turned off, you can remove the old gasket. To do this, use a putty knife to pry up the gasket around the edges. Be careful not to damage the bathtub. Once the gasket is loose, you can pull it out of the drain.

Step 3: Clean the drain.

Before you install the new gasket, you need to clean the drain. This will help to ensure that the new gasket seals properly. To do this, use a utility knife to scrape away any old sealant around the drain. Then, use a bucket and sponge to clean the drain thoroughly.

Step 4: Apply sealant.

Once the drain is clean, you can apply sealant around the edge of the new gasket. This will help to create a watertight seal. Be sure to use a sealant that is specifically designed for bathtubs.

Step 5: Install the new gasket.

Now you can install the new gasket. To do this, simply press the gasket into the drain. Be sure to press it firmly so that it creates a good seal.

Step 6: Turn on the water supply.

Once the new gasket is installed, you can turn on the water supply to the bathtub. Check the drain to make sure that there are no leaks. If you see any leaks, you may need to apply more sealant around the gasket.

Step 7: Clean up.

Finally, you can clean up the mess. Wipe down the bathtub and drain with a sponge. Then, dispose of the old gasket and sealant.

If you’re having trouble replacing the bathtub overflow gasket, here are a few troubleshooting tips:

  • Make sure that the new gasket is the right size for the drain.
