Replacing A Bathtub Faucet Stem

Replacing a Bathtub Faucet Stem: A Step-by-Step Guide

A leaky bathtub faucet can be a nuisance, wasting water and making a constant dripping sound. Replacing the faucet stem is often the solution to this problem, and it's a relatively easy DIY project that can be completed in a few hours.

Tools and Materials Needed:

Replacement faucet stem (match the brand and model of your faucet)
Adjustable wrench
Allen wrench (if required)
Plumber's putty
Clean rag or cloth

Step 1: Turn Off Water Supply

Start by turning off the water supply to your bathtub. There should be two shut-off valves located under the sink, one for hot water and one for cold water. Turn both valves clockwise until the water is completely shut off.

Step 2: Remove Handle

Once the water supply is turned off, remove the handle from the faucet. Most handles are held in place by a small screw or bolt. Loosen this screw or bolt and pull the handle straight off.

Step 3: Remove Escutcheon

The escutcheon is the decorative plate that covers the base of the faucet. Remove the escutcheon by unscrewing the screws that hold it in place. Some escutcheons may have a plastic clip that holds them in place instead of screws.

Step 4: Remove Cartridge or Stem

Once the escutcheon is removed, you will see the cartridge or stem. The type of cartridge or stem will vary depending on the model of your faucet.

For cartridge-type faucets, use an adjustable wrench to loosen the retaining nut and pull the cartridge straight out.

For stem-type faucets, use an Allen wrench to loosen the screw holding the stem in place. Then, use an adjustable wrench to loosen the packing nut and pull the stem straight out.

Step 5: Install New Stem or Cartridge

Apply a small amount of plumber's putty to the threads of the new stem or cartridge. Insert the new stem or cartridge into the faucet body and hand-tighten it as far as you can.

For stem-type faucets, tighten the packing nut using an adjustable wrench. Do not overtighten, as this can damage the packing nut.

Step 6: Reassemble Faucet

Reassemble the faucet by reversing the steps you took to disassemble it. First, place the escutcheon over the base of the faucet and secure it with the screws or plastic clip.

Next, install the handle and tighten the screw or bolt that holds it in place.
