Replace a Water Shut Off Valve Under a Bathroom Sink

A leaking water shut off valve under a bathroom sink can be a major inconvenience. Not only can it waste water and increase your water bill, but it can also lead to water damage if it's not fixed promptly. Replacing a water shut off valve is a relatively simple plumbing repair that most homeowners can do themselves with a few basic tools.

Here are the steps on how to replace a water shut off valve under a bathroom sink:

1. Gather your tools and materials.

You will need the following tools and materials to replace a water shut off valve:

Adjustable wrench
Plumber's putty
New water shut off valve
Bucket
Rags

2. Turn off the water supply.

The first step is to turn off the water supply to the bathroom sink. This is typically done by turning off the main water valve for the house. If you don't know where the main water valve is located, you can consult your home's owner's manual or ask a plumber.

3. Open the faucet.

Once the water supply is turned off, open the faucet to release any remaining water pressure in the line.

4. Remove the old shut off valve.

Use the adjustable wrench to loosen the nuts that hold the old shut off valve in place. Once the nuts are loose, you can remove the valve by hand.

5. Apply plumber's putty to the new shut off valve.

Roll a small piece of plumber's putty into a ball and apply it to the threads of the new shut off valve. This will help to create a watertight seal.

6. Install the new shut off valve.

Thread the new shut off valve onto the water supply line and tighten it with the adjustable wrench. Be sure not to overtighten the valve, as this can damage the valve or the water supply line.

7. Turn on the water supply.

Once the new shut off valve is installed, turn on the water supply and check for leaks. If there are any leaks, tighten the nuts on the valve until the leak stops.

8. Close the faucet.

Once the leak is stopped, close the faucet and you're finished!

Replacing a water shut off valve under a bathroom sink is a simple plumbing repair that can be completed in a few minutes. By following these steps, you can save yourself the cost of calling a plumber and have peace of mind knowing that your bathroom sink is leak-free.
