“How do I replace a shut off valve?” or “How do I replace that angle valve underneath my sink?”
The video above will walk you through the steps we have laid out in this post so you know exactly what to do.
First things first, you’re going to need a few tools. A good pair of pliers (channel locks work excellent in this case) and a good crescent wrench. Also, you may want a small little bucket, pail or rag to catch any residual water underneath that valve.
Make sure that you turn the water off to the house at the main water supply. Usually that’ll be located outside. If you do need help locating it or you need help turning it off, check some of our how-to videos because we do have some that cover that as well.

Remove water supply line
Now that the water’s off to the house, we’re going to go ahead and remove the supply water line from the actual valve. Some water will come out and that is okay.
One of the most important things that you’re going to want to remember is that when you go to remove the valve, you’ll see that it is connected to a nut, and then onto the pipe. This is called a compression fitting – which means that this nut needs to come off of the shut off valve.
There’s also another type of valve that just has threads on it, which will thread right onto the copper pipe. In this case, you want to make sure you verify which type of valve it is. In the video we are dealing with a compression fitting.
Remove original valve
Go ahead and grab your pliers here. Take the crescent wrench and put it on the shut off valve, making sure you hold it steady. Once you’ve got that in place, go ahead and put your channel locks or pliers on the nut. And then we’re going to go ahead and turn the nut to remove it.
Use your bucket to catch any of the water that comes out of the pipe. With the valve off, you can see that the nut is going to be stuck onto the pipe by this little brass ring, which is okay. You don’t need to replace it to replace the valve.
Replace the valve
Go ahead and grab your new valve, you’re going to slide it right over the copper pipe.
Hold the nut in place and then just go ahead and turn the shut off valve until you get it hand tight. Now that the valve’s in the place that we want it, you’re going to go ahead and tighten the nut the opposite way. Hold that shut-off valve with the crescent wrench and get it nice and tight.
Make sure you don’t apply too much pressure on the pipe that is in the wall. You don’t want to do any damage and snap it.
Attach supply line
Grab your supply line and get it back on the valve opening. Give it a few turns to get it nice and tight. Once it’s on there nice and tight, you can go ahead and turn the water back on to your home. After the water’s back on in the home, you can go ahead and test the valve to be sure for a leak free operation.
