How To Replace A Bathroom Valve

A dripping or leaking bathroom valve can be a major annoyance, not to mention a waste of water. If you're handy and have a few basic tools, you can replace a bathroom valve yourself and possibly avoid a costly plumber's visit.

Tools and Materials You'll Need:

New bathroom valve
Adjustable wrench
Basin wrench
Plumber's putty
Teflon tape
Bucket or bowl
Screwdriver (optional)

Step-by-Step Instructions:

1. Shut off the water supply: Locate the water supply valves beneath the sink and turn them off. If there are no valves, you'll need to shut off the main water supply to your home.

2. Open the faucet: Open the faucet to release any remaining water in the lines.

3. Remove the old valve: Using an adjustable wrench, loosen the packing nut around the base of the valve. Then, use a basin wrench to remove the valve body. Be careful not to damage the sink or countertop.

4. Clean the area: Remove any old plumber's putty or debris from the sink and valve body.

5. Apply plumber's putty: Roll a small piece of plumber's putty into a rope and wrap it around the threads of the new valve body. This will help create a watertight seal.

6. Apply Teflon tape: Wrap a few layers of Teflon tape around the threads of the new valve body in a clockwise direction. This will also help prevent leaks.

7. Install the new valve: Screw the new valve body into the sink by hand, then tighten it with a basin wrench. Do not overtighten.

8. Reinstall the handle: Place the handle over the valve stem and secure it with the screws.

9. Turn on the water supply: Slowly turn on the water supply valves beneath the sink. Check for any leaks around the valve.

10. Adjust the handle: If necessary, adjust the handle to the desired temperature and flow rate.

Tips:

If you're not confident in your abilities, it's best to call a plumber.
Be sure to use a new valve that is compatible with your sink and faucet.
Don't overtighten the valve body or handle, as this could damage the valve.
If you encounter any leaks, turn off the water supply and retighten the valve body or handle.

Conclusion:

Replacing a bathroom valve is a relatively simple plumbing repair that can be completed in under an hour. By following these instructions, you can save yourself time and money while ensuring a leak-free bathroom.
