A leaking bathtub faucet is not only annoying but can also lead to a significant increase in your water bill. If you notice that your bathtub faucet is dripping or leaking, it’s essential to fix it as soon as possible. In this blog, we will discuss how to fix a leaking bathtub faucet, including simple solutions that homeowners can implement.

  1. Identify the Type of Faucet The first step in fixing a leaking bathtub faucet is identifying the type of faucet you have. There are four common types of bathtub faucets: cartridge, compression, ball, and ceramic disc. Each type requires a different approach to fixing the leak. Knowing the type of faucet will help you find the right replacement parts and fix the leak quickly.
  2. Turn off the Water Supply Before you start fixing the faucet, you need to turn off the water supply to the bathtub. Look for the shutoff valve under the sink or near the water heater. Turning off the water supply will prevent any water from flowing while you work on the faucet.
  3. Remove the Faucet Handle After turning off the water supply, you need to remove the faucet handle. To do this, use a screwdriver to remove the screws that hold the handle in place. You can also use a hex wrench or an Allen wrench, depending on the type of faucet you have. Once you remove the handle, you will have access to the faucet cartridge.
  4. Inspect the Cartridge The cartridge is the component that controls the flow of water in the faucet. Inspect the cartridge for any damage or wear and tear. If the cartridge is damaged, you will need to replace it. You can purchase a replacement cartridge at your local hardware store or online.
  5. Replace the Cartridge To replace the cartridge, follow the instructions that come with the replacement part. Make sure to apply plumber’s grease to the o-rings before installing the new cartridge. This will prevent leaks and ensure a smooth operation of the faucet.
  6. Reassemble the Faucet After replacing the cartridge, reassemble the faucet handle and turn on the water supply. Check for any leaks and test the faucet to ensure it’s working correctly.
  7. Call a Professional If you’re not comfortable fixing the leaking bathtub faucet on your own, it’s best to call a professional plumber. A plumber will be able to identify the problem and fix the leak quickly and efficiently.
