Unclog your plumbing nightmare: how to remove pex pipe from fitting in 5 easy steps

PEX pipes, known for their flexibility and durability, often require removal from fittings for various reasons, such as repairs, renovations, or plumbing upgrades. However, detaching PEX pipes from fittings can be a daunting task without proper knowledge and techniques. This comprehensive guide will provide step-by-step instructions and essential tips on how to remove PEX pipe from fitting, ensuring a successful and efficient process.

Tools and Materials Required

• PEX removal tool or a flat-head screwdriver
• Slip-joint pliers
• Adjustable wrench
• Utility knife
• Clean cloth or rag

Safety Precautions

Before commencing the removal process, it’s crucial to follow these safety precautions:

• Turn off the water supply to the affected area.
• Wear safety glasses and gloves to protect against potential water leaks or sharp edges.

Step-by-Step Instructions

1. Identify the Type of Fitting

There are two main types of PEX fittings: crimp fittings and push-fit fittings. Crimp fittings require a PEX removal tool, while push-fit fittings can be removed using a flat-head screwdriver.

2. Remove the Crimp Ring (for Crimp Fittings Only)

Using the PEX removal tool, insert the prongs into the crimp ring and squeeze the handles to release the ring. Alternatively, a flat-head screwdriver can be used to pry the ring off.

3. Pull the Pipe from the Fitting

Once the crimp ring is removed, use slip-joint pliers to grip the PEX pipe and pull it straight out of the fitting. Do not twist or bend the pipe excessively.

4. Clean the Pipe and Fitting

Use a utility knife to remove any burrs or debris from the pipe and fitting. Wipe both surfaces clean with a cloth or rag.

5. Lubricate the Pipe (for Push-Fit Fittings Only)

Apply a small amount of silicone lubricant to the end of the PEX pipe. This will make it easier to slide the pipe back into the fitting.

6. Reassemble the Fitting (for Push-Fit Fittings Only)

Insert the lubricated PEX pipe into the push-fit fitting and push it until it clicks into place. Ensure the pipe is fully inserted and secure.

7. Tighten the Fitting (for Crimp Fittings Only)

Using an adjustable wrench, tighten the crimp ring back onto the fitting. Make sure it is snug but not overtightened.

Tips for Successful Removal

• Use the correct tools for the job.
• Be patient and avoid using excessive force.
• If the pipe is stuck, try heating it with a heat gun to soften the plastic.
• If the fitting is damaged, it may need to be replaced.
• Practice on scrap pieces of PEX pipe before attempting the actual removal.

Troubleshooting Common Issues

Problem: The crimp ring is stuck.

Solution: Use a penetrating oil or lubricant to loosen the ring.

Problem: The pipe is not coming out of the fitting.

Solution: Check if the crimp ring is properly removed. If it is, try pulling the pipe with more force or using a pry bar.

Problem: The fitting is leaking after reassembly.

Solution: Make sure the pipe is fully inserted into the fitting and the crimp ring is tightened securely.

Final Thoughts

Removing PEX pipe from fittings can be a straightforward task with the right tools and techniques. By following the steps outlined in this guide and addressing any potential issues, you can ensure a successful and hassle-free removal process.
