How To Stop A Leaky Bathtub Faucet

If you’re tired of the constant dripping sound coming from your bathtub faucet, it’s time to take action. A leaky bathtub faucet not only wastes water, but it can also lead to high water bills. In this article, we’ll guide you through the steps on how to stop a leaky bathtub faucet.

Tools and Materials

Before you start fixing your leaky bathtub faucet, you’ll need to gather the necessary tools and materials. Here’s a list of what you’ll need:

  • Adjustable wrench
  • Flathead screwdriver
  • New faucet cartridge
  • Plumber’s tape
  • Rag or towel

Identifying the Problem

The first step in fixing a leaky bathtub faucet is identifying the problem. There are several reasons why your faucet may be leaking, including a worn-out washer, damaged valve seat, or a faulty cartridge. Once you determine the cause, you can proceed with the appropriate solution.

Checking the Washer

A worn-out washer is a common cause of a leaky bathtub faucet. To check if this is the problem, turn off the water supply to the faucet and remove the handle. Next, unscrew the packing nut and remove the stem. You should see a rubber washer at the bottom of the stem. If it’s worn out, replace it with a new one.

Inspecting the Valve Seat

If the washer isn’t the problem, the valve seat may be damaged. The valve seat is the connection between the faucet and the spout. Over time, it can become corroded or worn out, causing leaks. To inspect the valve seat, remove the stem and use a flashlight to check its condition. If it’s damaged, replace it with a new one.

Replacing the Cartridge

If neither the washer nor the valve seat is the problem, the cartridge may be faulty. The cartridge is the heart of the faucet and controls the water flow. To replace it, turn off the water supply and remove the handle. Next, remove the retaining clip and pull out the cartridge. Replace it with a new one and reassemble the faucet.
