What Causes a Bathtub Faucet to Leak?

The most common causes of a leaking bathtub faucet are a corroded washer or a failing cartridge. In some cases, it could be old bathtub faucet handles that have worn over time; generally, it’s easier to identify because you will notice rust or cracking. If the source of the bathtub faucet leak is the pipe leading to the faucet, the repair may be trickier and require the help of a plumber.

Before You Start the Bathtub Faucet Repair:

Locate your home’s water shut-off valve, usually in the basement, and turn off the water supply. Once closed, turn on the bathtub faucet to drain any remaining water in the pipe.

Instructions:

Step 1: Remove the Bathtub Faucet Handle

Every bathtub faucet cover might be slightly different. Start by assessing what screwdriver or Allen wrench you need to remove the cover from your single-handle bathtub faucet. Gently remove the handle and set it aside on a towel with its corresponding screws.

Step 2: Remove the Trim Sleeve or Trim Plate

Unscrew the screws using whatever corresponding screwdriver or Allen wrench best suits your bathtub faucet.

Step 3: Remove the Bonnet or Retainer Clip

Depending on how your bathtub faucet is constructed, use channel lock pliers to remove the bonnet/retainer nut or use your pliers to grab the top of the retainer clip and pull up to remove it. Place these pieces on the towel as well.

Step 4: Remove the Bathtub Faucet Cartridge

Use your hand or a pair of pliers to remove the cartridge from the faucet, pulling it straight out of the faucet handle. Don’t be discouraged if it takes a little bit of strength to remove this piece. Once out, compare your old cartridge to the new one to ensure you’ve purchased the right one. Check the interior opening to make sure the metal doesn’t look corroded or damaged.

Step 5: Install the New Bathtub Faucet Cartridge

Push the new cartridge into the bathtub faucet opening, making sure to line up the corresponding grooves so it clicks into place. Replace the bonnet nut or retainer clip.

Step 6: Check Your Work for Leaks

Go to the water valve that you turned off and turn it back on to check for leaks around the bathtub faucet. Look beyond the cartridge you just replaced to see if there is another source for the leak. If everything looks good, reassemble the bathtub faucet with its trim plate.
