You’ll need a new toilet flapper, which can be purchased at any hardware store. Have a pair of pliers, a sponge, and a towel on hand. The pliers will help you remove any stubborn parts, while the sponge and towel will be useful for cleaning up any water spills.

Turn Off the Water Supply

The first step in how to change a toilet flapper is to turn off the water supply to the toilet. Locate the water shut-off valve, usually found on the wall behind the toilet, and turn it clockwise to close it.

Once the water supply is off, flush the toilet to drain the tank. This ensures that you won’t have a mess on your hands while replacing the flapper. Use the sponge to soak up any remaining water in the tank to keep your workspace dry.

Remove the Old Flapper

Once the water is turned off and the tank is empty, it’s time to remove the old flapper. To do this, take off the lid of the toilet tank and locate the flapper at the bottom. The flapper is usually attached to the overflow tube with a chain. Disconnect the chain from the flush lever and then unhook the flapper from the overflow tube.

If the flapper is stuck, use your pliers to gently loosen it. Once removed, inspect the flapper for any signs of wear and tear, which could be causing the leak.

Install the New Flapper

Now that the old flapper is out, you can install the new one. Make sure the new flapper is compatible with your toilet model. Attach the new flapper to the overflow tube by hooking it onto the ears or loops on the tube.

Then, reattach the chain to the flush lever. The chain should have a little slack but not so much that it gets tangled. Adjust the chain length if necessary to ensure a proper fit.

Test the New Flapper

After installing the new flapper, it’s important to test it to make sure it works correctly. Turn the water supply back on by rotating the shut-off valve counterclockwise.

Allow the tank to fill up and then flush the toilet. Watch the flapper as it operates to ensure it seals properly and stops the water flow when the tank is full. If the toilet continues to run, adjust the chain or reposition the flapper until it works correctly.

Final Touches and Maintenance Tips

Once you’re satisfied that the new flapper is working correctly, replace the lid on the toilet tank. To ensure your toilet flapper continues to function well, perform regular maintenance checks.

Periodically inspect the flapper for any signs of wear and replace it as needed. Additionally, keep an eye on the water level in the tank to ensure it’s not too high, as this can put extra strain on the flapper and cause it to wear out faster.
