How to Replace an Old Bathtub Faucet Valve

If your bathtub faucet is leaking or dripping, it's likely that the valve needs to be replaced. Replacing a bathtub faucet valve is a relatively simple plumbing project that can be completed in about an hour. Here are the steps on how to do it:

Tools and Materials You'll Need:

New bathtub faucet valve
Adjustable wrench
Plumber's putty
Screwdriver
Rags

Step 1: 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 shut off the water supply.

Step 2: Remove the old faucet handle. Use a screwdriver to remove the screws that hold the handle in place. Once the screws are removed, you should be able to pull the handle off.

Step 3: Remove the old valve. Use an adjustable wrench to loosen the nut that holds the valve in place. Once the nut is loose, you should be able to pull the valve out.

Step 4: Install the new valve. Apply a bead of plumber's putty to the threads of the new valve. Then, insert the valve into the faucet body and tighten the nut until it is snug.

Step 5: Reinstall the faucet handle. Place the handle over the valve stem and tighten the screws until it is secure.

Step 6: Turn on the water supply. Slowly turn on the shut-off valves under the sink to turn on the water supply. Check for any leaks. If there are any leaks, tighten the packing nut on the valve until the leak stops.
