Replace Bathtub Handle Stem

Replacing a bathtub handle stem is a relatively simple plumbing repair that can be completed in a few steps. However, it is important to note that this repair should only be attempted by someone who is comfortable working with plumbing fixtures.

The first step is to turn off the water supply to the bathtub. Once the water is turned off, you can remove the handle by unscrewing the set screw that is located on the side of the handle. Once the set screw is removed, you can pull the handle straight off of the stem.

Next, you need to remove the stem. To do this, you will need to use a wrench to loosen the packing nut that is located at the base of the stem. Once the packing nut is loosened, you can pull the stem straight out of the faucet body.

Before you install the new stem, you need to apply a small amount of plumber's grease to the O-rings. This will help to create a watertight seal. Once the O-rings are greased, you can insert the new stem into the faucet body.

Next, you need to tighten the packing nut. To do this, you will need to use a wrench to tighten the packing nut until it is snug. Be careful not to overtighten the packing nut, as this could damage the faucet body.

Finally, you can reattach the handle to the stem. To do this, you simply need to slide the handle onto the stem and tighten the set screw. Once the set screw is tightened, you can turn the water supply back on and check for leaks.

If you are not comfortable working with plumbing fixtures, it is best to call a plumber to replace the bathtub handle stem for you.
