How to remove compression fitting

Compression fittings are widely used in plumbing and gas fitting projects as they provide a high level of sealing and connect pipes and fittings with ease. Whether you need to replace an old compression fitting or simply need to remove it for maintenance purposes, it’s essential to do it safely and correctly to avoid any damage or injuries. In this article, we will explain how to remove compression fittings step by step and some important matters needing attention.

Step 1: Shut off the water supply

Before removing any compression fittings, it’s essential to turn off the water supply first to prevent any water from flowing through the pipes. Locate the main valve that enters your home or the valve that goes to the specific area where you’re working. Valve handles can often be turned by hand or with pliers. If you’re unsure where the valve is, consult with a professional plumber or gas fitter.

Step 2: Prepare the work area

Clear the area where you will be working, placing a bucket or a bowl beneath the fitting to catch any water that may come out during the removal process. It’s essential to wear protective gloves and goggles to prevent any injury from hot or harmful substances.

Step 3: Release the compression fitting

Use a wrench to unscrew the compression nuts that are holding the fitting in place, turning them in a counterclockwise direction. If the fitting is stuck or difficult to turn, apply a lubricant such as WD-40 to loosen it. Avoid using excessive force, as this could cause damage to the pipes or fittings.

Step 4: Remove the fitting

Once the compression nuts are loosened, pull the fitting and pipe out of the connection. If the fitting is stubborn, use pliers to grip the fitting and tug it out gently. While removing the fitting, be mindful of the pipe's condition and ensure that it doesn't suffer any damage or kinks in the process.

Matters needing attention:

1. Safety first

Always make sure to wear the proper protective gear, such as gloves and goggles, when working with compression fittings, as they can be sharp and potentially harmful.

2. Use the right tool

Using the appropriate tools can make a significant difference in dismantling a compression fitting. The ideal tools for compression fittings include adjustable wrenches, pliers, and tube cutters.

3. Turn off the water supply

Before removing any compression fitting, time must be taken to turn off the water supply to prevent any potential water damage.

4. Label the pipes

When removing a compression fitting, ensure that the pipes are correctly labeled if there are multiple connections nearby. Labeling helps to remember the positioning of the pipes and eases reconnection later.

5. Check the pipe’s condition.

Care should be taken to examine the condition of the pipe after removing a compression fitting. If the pipe looks damaged or bent, consider replacing it.

In summary, removing a compression fitting involves shutting off the water supply, preparing the workspace and safety gear, releasing the compression fitting, and finally removing the fitting with caution. Always remember to use the correct tools and avoid using excessive force to prevent any damage to pipes and fittings. With patience and care, the removal process can be completed smoothly and safely.
