How to Change a Bathtub Faucet Stem

Replacing a bathtub faucet stem is a simple plumbing repair that can be completed in about 30 minutes. A worn or damaged stem can cause a faucet to leak or drip, so it's important to replace it as soon as possible.

### Tools and Materials * Adjustable wrench * Allen wrench (if necessary) * Flathead screwdriver * New faucet stem ### Step-by-Step Instructions 1.

Turn off the water supply.

There are usually two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves off completely. 2.

Open the faucet.

This will release any remaining water pressure in the lines. 3.

Remove the faucet handle.

Most faucet handles are held in place by a small screw. Use a flathead screwdriver to remove the screw, then pull the handle off. 4.

Remove the packing nut.

The packing nut is a large nut that is located behind the handle. Use an adjustable wrench to loosen the packing nut and remove it. 5.

Remove the stem.

The stem is a long, metal rod that is threaded into the faucet body. Use an adjustable wrench or Allen wrench to loosen the stem and remove it. 6.

Install the new stem.

Apply a small amount of plumber's grease to the threads of the new stem. Then, thread the stem into the faucet body. Tighten the stem with an adjustable wrench or Allen wrench. 7.

Replace the packing nut.

Place the packing nut over the stem and tighten it with an adjustable wrench. Be careful not to overtighten the packing nut, as this can damage the stem. 8.

Reinstall the faucet handle.

Push the handle back onto the stem and secure it with the screw. 9.

Turn on the water supply.

Slowly turn on the shut-off valves under the sink to allow water to flow into the faucet. Check for leaks around the stem. ### Troubleshooting If you experience any problems while changing the faucet stem, here are a few troubleshooting tips: * If the faucet still leaks after you have replaced the stem, the leak may be coming from another part of the faucet. Call a plumber for assistance. * If you cannot remove the packing nut, you may need to use a penetrating oil to loosen it. Apply the penetrating oil to the packing nut and let it sit for a few minutes before trying to remove it. * If you cannot remove the stem, you may need to use a hammer and chisel to break it loose. Be careful not to damage the faucet body when using a hammer and chisel.
