How to Replace a Tub Faucet Stem

Your tub faucet is one of the most important fixtures in your bathroom, and it’s important to keep it in good working order. If your tub faucet stem is leaking or not working properly, you’ll need to replace it. This is a relatively simple task that can be completed in about an hour.

In this article, we’ll walk you through the steps of replacing a tub faucet stem. We’ll provide detailed instructions and images to help you along the way. So whether you’re a DIY novice or a seasoned pro, you’ll be able to get the job done in no time.

Step 1: Gather your tools and materials

Before you begin, gather the following tools and materials:

  • Replacement tub faucet stem
  • Adjustable wrench
  • Penetrating oil
  • Pliers
  • Flathead screwdriver
  • Tape measure
  • Bucket
  • Towels

Step 2: Shut off the water supply

The first step is to shut off the water supply to the tub faucet. This is usually located at the back of the faucet, near the wall. Turn the valve clockwise until it’s completely closed.

Step 3: Remove the old stem

Now it’s time to remove the old stem. To do this, you’ll need to use an adjustable wrench to loosen the locknut that holds the stem in place. The locknut is usually located at the base of the faucet.

Once the locknut is loosened, you can use a pair of pliers to grip the stem and turn it counterclockwise. The stem should come out easily.

Step 4: Clean the threads

Before you install the new stem, it’s important to clean the threads on the faucet body. This will help to ensure that the new stem seals properly.

To clean the threads, use a rag or paper towel to wipe away any dirt or debris. You can also use a little penetrating oil to help loosen any stubborn deposits.

Step 5: Apply thread sealant

Once the threads are clean, apply a small amount of thread sealant to the threads of the new stem. This will help to create a watertight seal.

Step 6: Install the new stem

Now it’s time to install the new stem. To do this, simply reverse the steps you took to remove the old stem.

First, insert the stem into the faucet body. Then, use the adjustable wrench to tighten the locknut until it’s snug.

Step 7: Turn on the water supply

Now it’s time to turn on the water supply and test the faucet. Make sure that the faucet is working properly and that there are no leaks.

If you have any problems, consult a qualified plumber.
