Identify the Problem

  • The faucet is dripping. This is the most common type of leak. It can be caused by a worn-out washer or a loose cartridge.
  • The faucet is leaking when it’s turned off. This is usually caused by a faulty O-ring.
  • The faucet is leaking when it’s turned on. This can be caused by a problem with the valve seat or the stem.

To identify the problem, you’ll need to turn on the faucet and watch where the leak is coming from. If the leak is coming from the faucet itself, you’ll need to remove the faucet to fix it. If the leak is coming from the pipes behind the faucet, you’ll need to shut off the water supply and replace the pipes.

  • Adjustable wrench

  • Penetrating oil
  • New washer or cartridge (if needed)

Step-by-step Instructions

To fix a leaky bathtub faucet, you will need the following tools:

  • A screwdriver

7. Turn on the water supply to the faucet. Test the faucet to make sure that the leak has been fixed.
