What You'll Need

Installing a water shut off valve for your bathroom sink is something that should be done. It creates an easier way of turning off water, so you are not required to turn off the main water when working on bathroom projects. Below are the supplies needed to conquer this project, as well as the steps needed to be taken.

Step 1 - Decide and Purchase

The first thing you will want to do is to decide whether you are going to install straight shut off valves, or angle ones. This is decided by figuring out how your plumbing is done.

If it comes up through the floor of your bathroom, you will need to install straight shut off valves. However, if the plumbing protrudes from the wall, you can use either straight or angle shut off valves. Then the decision is up to you. Each type of valve is available at your local hardware store.

Step 2 - Measure

Now you will need to decide where exactly you want to put your shut off valve. Take our your tape measure and measure how far your faucet is away from this installation area.

Step 3- Shut Water Off

It's now time to shut off the water so you can get to work. You, of course will need to shut off the main water valve, and then turn on a faucet to drain out any excess water that was in the pipes. Make sure all water is turned off before you continue on to the next step.

Step 4 - Disconnect Water Supply

Locate the water supply line, and disconnect it from your sink.

Step 5 - Attach

You will want to take your compression nut and ring and place it on to the pipe. You will want to make sure that the nuts threads and the open part of the pipe face each other.

Step 6 - Tape

Take your Teflon tape and wrap it around the pipe; then take a compression nut and ring once again, and tighten them so it is next to the valve.

Step 7 - Connect

Connect the compression fitting to the other end of the valve, and secure it down. Then take the opposite end and attach it to the bottom of the faucet and tighten it into place.

Step 8 - Tighten Once More

Now that you have installed the shut off valve, you will want to go around to each section, and make sure all connections are tight. This is needed, to help prevent any leakage from happening. Use your wrench, and give it one last twist to tighten it fully.

Step 9 - Turn on Water and Test

Now you can turn back on the main water. Turn on your faucet to make sure all is working. If it seems good, try turning it off using the new shut off valve you just installed.
