How To Remove Compression Fitting

What is a Compression Fitting?

A compression fitting is a type of plumbing fitting that connects two pipes or tubes together using compression or squeezing force. It consists of three parts: a compression nut, a compression ring, and a compression seat. The compression nut applies pressure to the compression ring, which in turn presses against the compression seat and creates a watertight seal.

Why Do You Need to Remove Compression Fitting?

There are several reasons why you may need to remove a compression fitting. One of the most common reasons is leakage. If you notice water dripping from the fitting or pipe, it may be due to a damaged or worn-out compression ring or seat. Another reason is replacement. If you need to replace the pipe or fitting, you will need to remove the compression fitting first. Lastly, you may need to remove a compression fitting if you are reconfiguring your plumbing system.

Tools You Need to Remove Compression Fitting

Before you start removing the compression fitting, you need to gather the necessary tools. Here are the tools you will need:

• Adjustable wrench
• Pipe cutter or hacksaw
• Plumber’s tape
• Clean cloth or rag

Steps on How to Remove Compression Fitting

Now that you have the tools, you can proceed with removing the compression fitting. Follow these steps:

1. Turn off the water supply. Before you start working on the compression fitting, you need to turn off the water supply to avoid any water spillage or damage.
2. Prepare the pipe. If the pipe is old or rusty, you may need to clean it with a clean cloth or rag. You may also need to cut the pipe if it’s damaged or worn out. Use a pipe cutter or hacksaw to cut the pipe.
3. Loosen the compression nut. Use an adjustable wrench to loosen the compression nut. Turn it counterclockwise to loosen it. Be careful not to damage the threads or the nut itself.
4. Remove the compression ring and seat. Once you have loosened the compression nut, you can remove the compression ring and seat. You may need to use pliers or a screwdriver to pry them off.
5. Remove the compression fitting. Once you have removed the compression ring and seat, you can remove the compression fitting from the pipe.
6. Clean the pipe. Use a clean cloth or rag to clean the pipe and remove any debris or dirt.
7. Wrap the threads with plumber’s tape. Before you install a new compression fitting, you need to wrap the threads with plumber’s tape to create a watertight seal.
8. Install the new compression fitting. Insert the new compression fitting onto the pipe and tighten the compression nut using an adjustable wrench. Make sure it’s tight enough to create a watertight seal but not too tight to damage the fitting or pipe.
9. Turn on the water supply. Once you have installed the new compression fitting, you can turn on the water supply and check for leaks.

FAQs about How to Remove Compression Fitting

1. Can I reuse a compression fitting?

It’s not recommended to reuse a compression fitting. Compression fittings are designed to create a watertight seal by squeezing the ring against the seat. Once you have removed the compression fitting, the ring may lose its shape or elasticity, which can affect its ability to create a seal. It’s better to use a new compression fitting.

2. How do I know if the compression fitting is damaged?

If you notice water dripping from the fitting or pipe, it may be due to a damaged or worn-out compression ring or seat. You may also notice discoloration or rust around the fitting, which can indicate a leak.

3. Do I need to turn off the water supply before removing the compression fitting?

Yes, you need to turn off the water supply before working on the compression fitting to avoid any water spillage or damage.

Conclusion

Removing a compression fitting may seem daunting, but it’s a straightforward process if you have the right tools and follow the steps correctly. Remember to turn off the water supply, prepare the pipe, loosen the compression nut, and remove the compression ring and seat before removing the compression fitting. Once you have removed the fitting, clean the pipe, wrap the threads with plumber’s tape, install the new compression fitting, and turn on the water supply to check for leaks. If you have any doubts or questions, don’t hesitate to consult a professional plumber.
