How To Change Shut Off Valve Under Bathroom Sink

If you're experiencing a leak under your bathroom sink, chances are the shut off valve is to blame. The shut off valve is a small valve that controls the flow of water to the sink. Over time, these valves can become worn or damaged, leading to leaks. Replacing a shut off valve is a relatively simple plumbing repair that can be completed in a few minutes with the right tools and materials.

Before you begin, you'll need to gather a few tools and materials. You'll need a new shut off valve, a wrench, a pair of pliers, and a bucket to catch any water that may leak out. You may also want to wear gloves to protect your hands.

Once you have your tools and materials, you can begin the repair. First, turn off the water supply to the sink. To do this, locate the main water shut off valve for your home and turn it clockwise to the off position. Once the water supply is turned off, open the faucet to release any remaining water in the pipes.

Next, place the bucket under the sink to catch any water that may leak out. Then, use the wrench to loosen the nut that holds the shut off valve in place. Once the nut is loose, you can use the pliers to remove the old shut off valve. Be careful not to damage the pipes when you remove the old valve.

Now, take the new shut off valve and insert it into the pipe. Hand-tighten the nut that holds the valve in place. Then, use the wrench to further tighten the nut. Be careful not to overtighten the nut, as this could damage the valve.

Once the new shut off valve is installed, turn on the water supply to the sink. Check for leaks around the valve. If you notice any leaks, tighten the nut further. Once you're satisfied that there are no leaks, you can close the faucet and replace the bucket.

Replacing a 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.
