The ultimate guide to removing stubborn compression fittings from copper pipe

Compression fittings are a common type of plumbing connection used to join copper pipes. They are easy to install and remove, making them a popular choice for DIY plumbing projects. However, if you are not familiar with how to remove compression fittings from copper pipe, you may damage the pipe or the fitting.

Tools You Will Need

Before you begin, you will need to gather the following tools:

• Adjustable wrench
• Basin wrench
• Hacksaw
• File
• Emery cloth
• Plumber’s putty
• Teflon tape

Safety Precautions

Before you begin working, be sure to take the following safety precautions:

• Wear safety glasses to protect your eyes from flying debris.
• Shut off the water supply to the pipe you are working on.
• Open the faucet to release any residual water pressure.

Step-by-Step Instructions

1. Loosen the compression nut. Using an adjustable wrench, loosen the compression nut that is located at the end of the fitting. Do not remove the nut completely.

2. Slide the compression ring back. Once the compression nut is loosened, you can slide the compression ring back towards the body of the fitting.

3. Pull the fitting away from the pipe. Once the compression ring is slid back, you can pull the fitting away from the pipe.

4. Clean the pipe and fitting. Use a file and emery cloth to clean any corrosion or debris from the pipe and fitting.

5. Apply plumber’s putty to the pipe. Apply a thin layer of plumber’s putty to the end of the pipe. This will help to create a watertight seal.

6. Wrap the pipe with Teflon tape. Wrap several layers of Teflon tape around the threads of the pipe. This will also help to create a watertight seal.

7. Reassemble the fitting. Slide the compression ring back onto the pipe. Then, tighten the compression nut until it is snug. Do not overtighten the nut, as this can damage the fitting.

8. Turn on the water supply. Once the fitting is reassembled, turn on the water supply and check for leaks. If there are any leaks, tighten the compression nut further.

Troubleshooting

If you are having trouble removing a compression fitting from copper pipe, try the following:

• Use a basin wrench. A basin wrench is a specialized tool that is designed to remove compression fittings. It can provide you with more leverage than an adjustable wrench.

• Cut the fitting off. If you are unable to remove the fitting using the above methods, you can cut it off using a hacksaw. Be careful not to damage the pipe when you are cutting the fitting.

Recommendations: Mastering Copper Compression Fitting Removal

By following these steps, you can safely and easily remove compression fittings from copper pipe. With a little practice, you will be able to master this plumbing task in no time.

What You Need to Learn

1. Can I use a regular wrench to remove a compression fitting?

Yes, you can use a regular adjustable wrench to remove a compression fitting. However, a basin wrench is a better choice because it is designed specifically for this task.

2. What is the best way to clean a copper pipe before installing a compression fitting?

Use a file and emery cloth to clean any corrosion or debris from the pipe. You can also use a wire brush to clean the inside of the pipe.

3. How tight should I tighten the compression nut?

Tighten the compression nut until it is snug. Do not overtighten the nut, as this can damage the fitting.

4. What should I do if there is a leak after I install a compression fitting?

If there is a leak after you install a compression fitting, tighten the compression nut further. If the leak persists, you may need to replace the compression ring or the fitting itself.

5. Can I use compression fittings on PEX pipe?

No, compression fittings are not designed for use on PEX pipe. Use crimp rings or expansion fittings to connect PEX pipe.
