To remove a compression-style faucet shut off valve, you'll need a couple of wrenches and a bit of careful maneuvering. Here's how:
-
Turn off the Water: Before you begin, completely shut off the main water supply to your house or at least to the plumbing line feeding the valve you intend to remove. This is crucial to prevent flooding.
-
Relieve Pressure: Open the faucet that the shut-off valve serves. This will relieve any residual pressure in the pipes.
-
Prepare Your Tools: You'll need two wrenches:
- One adjustable wrench, open-end wrench, or slip-joint pliers to grip the body of the shut-off valve.
- Another wrench (usually an adjustable wrench or an open-end wrench) to loosen the compression nut.
-
Loosen the Compression Nut: Grip the shut-off valve body firmly with your first wrench to prevent it from turning. With your second wrench, grab the compression nut (the nut that connects the valve to the copper tubing). Turn the nut clockwise to loosen it. This may require some force, but avoid excessive force that could damage the tubing.
-
Remove the Valve: Once the compression nut is loosened, carefully pull the shut-off valve away from the copper tubing. It might take a bit of wiggling.
Important Considerations:
- Type of Valve: This procedure applies specifically to compression-style shut-off valves. Other types, such as soldered or push-fit valves, will require different removal methods. Soldered valves require a torch and soldering skills, while push-fit valves usually have a release collar.
- Inspect the Tubing: Once the valve is removed, inspect the copper tubing for any damage or corrosion. Clean the tubing with emery cloth to ensure a clean surface for installing a new valve.
- Compression Sleeve (Ferrule): When you remove the valve, you will likely see a small brass ring (the compression sleeve or ferrule) on the copper pipe. This ferrule is usually crimped onto the pipe and is not reusable. You might be able to carefully cut it off with a utility knife or use a ferrule puller if you have one. Depending on the new valve you're installing, you may need to purchase a new ferrule.
- Replacing the Valve: When installing a new compression valve, ensure you use new compression nuts and ferrules for a secure, leak-free connection. Teflon tape can also be used on the threads.
- Safety First: Always prioritize safety. If you're uncomfortable performing this task, it's best to call a qualified plumber.
