How To Fix A Leaky Bathtub Faucet: A Step-by-step Guide

If your bathtub valve is acting up, you’re not alone. This common plumbing problem can be frustrating and inconvenient, but it’s usually not difficult to fix. With the right tools and a little know-how, you can get your bathtub faucet working like new again in no time.

Tools and Materials You’ll Need

Before you start, gather the following tools and materials:

• Adjustable wrench
• Phillips head screwdriver
• Flat head screwdriver
• Plumber’s putty
• Teflon tape
• Replacement valve cartridge (if necessary)

Step-by-Step Instructions

1. Turn Off the Water Supply

The first step is to turn off the water supply to your bathtub. This will prevent water from spraying everywhere when you start working on the valve. There should be two shut-off valves under your sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water supply.

2. Remove the Handle

Once the water is turned off, you can remove the handle from the valve. Most handles are held on by a screw or a cap. Use a screwdriver to remove the screw or unscrew the cap. Once the screw or cap is removed, you can pull the handle straight off.

3. Remove the Valve Cartridge

With the handle removed, you will see the valve cartridge. The valve cartridge is a cylindrical-shaped piece of metal that controls the flow of water. To remove the valve cartridge, use an adjustable wrench to loosen the packing nut. The packing nut is located at the base of the valve cartridge. Once the packing nut is loose, you can pull the valve cartridge straight out.

4. Inspect the Valve Cartridge

Once you have removed the valve cartridge, inspect it for any damage. If the valve cartridge is damaged, it will need to be replaced. If the valve cartridge is not damaged, you can clean it with a mild detergent and water.

5. Install the New Valve Cartridge (if necessary)

If you are replacing the valve cartridge, insert the new cartridge into the valve body. Hand-tighten the cartridge as much as possible. Then, use an adjustable wrench to tighten the packing nut. Do not overtighten the packing nut, as this could damage the valve cartridge.

6. Reinstall the Handle

Once the valve cartridge is installed, you can reinstall the handle. Align the handle with the valve stem and push it on until it snaps into place. If the handle is loose, you can tighten it with a screwdriver.

7. Turn On the Water Supply

Once the handle is reinstalled, turn on the water supply to your bathtub. Check for leaks around the valve. If there are any leaks, tighten the packing nut until the leak stops.

Troubleshooting Tips

If you are having trouble fixing your bathtub valve, here are a few troubleshooting tips:

• The handle is loose. If the handle is loose, tighten the screw or cap that holds it in place.
• The water is not turning on. If the water is not turning on, make sure that the water supply is turned on and that the valve cartridge is properly installed.
• The water is leaking. If the water is leaking, tighten the packing nut until the leak stops.

Takeaways

Fixing a bathtub valve is a relatively simple plumbing repair that can be completed in a few hours. By following these step-by-step instructions, you can get your bathtub faucet working like new again in no time.
