Installing A Bathtub Faucet Stem

Installing a Bathtub Faucet Stem

Replacing a bathtub faucet stem is a relatively simple plumbing repair that can be completed in about 30 minutes with the right tools and materials. Here is a step-by-step guide on how to install a bathtub faucet stem:

Step 1: Gather your tools and materials.

Before you begin, you'll need to gather the following tools and materials:

Phillips head screwdriver
Flat head screwdriver
Adjustable wrench
New bathtub faucet stem
Plumber's putty
Cloth or sponge

Step 2: Turn off the water supply.

Before you begin working on the faucet, you'll need to turn off the water supply. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to turn off the water.

Step 3: Remove the faucet handle.

Once the water is turned off, you can remove the faucet handle. Most faucet handles are held in place by a small screw. Use a Phillips head screwdriver to remove the screw, and then pull the handle straight off.

Step 4: Remove the packing nut.

Once the handle is removed, you'll see the packing nut. The packing nut is a large nut that holds the stem in place. Use an adjustable wrench to loosen the packing nut, and then remove it by hand.

Step 5: Remove the stem assembly.

Once the packing nut is removed, you'll be able to remove the stem assembly. The stem assembly is made up of the stem, the washer, and the spring. Grip the stem with a pair of pliers, and pull it straight out of the faucet body.

Step 6: Install the new stem assembly.

Take the new stem assembly and insert it into the faucet body. Make sure that the washer is facing down, and that the spring is in place. Tighten the packing nut by hand, and then use an adjustable wrench to further tighten it. Do not overtighten the packing nut, as this can damage the stem.

Step 7: Reinstall the faucet handle.

Once the stem assembly is installed, you can reinstall the faucet handle. Slide the handle onto the stem, and then tighten the screw to secure it in place.

Step 8: Turn on the water supply and check for leaks.

Once the faucet handle is installed, you can turn on the water supply and check for leaks. If there are any leaks, tighten the packing nut a little bit more. If the leak persists, you may need to replace the washer.
