- It’s not recommended to use pliers to remove PEX fittings as they can damage the fitting or the PEX pipe.
PEX (cross-linked polyethylene) fittings offer a convenient and reliable way to connect pipes in plumbing systems. However, when it comes to removing these fittings, it can be a daunting task if you don’t have the right tools and techniques. This comprehensive guide will provide you with a step-by-step approach to safely and effectively remove PEX fittings.
Understanding PEX Fittings
Before attempting to remove PEX fittings, it’s essential to understand their design. PEX fittings typically consist of a brass or plastic insert that’s crimped or clamped onto the PEX pipe. The insert has teeth or barbs that grip the pipe, creating a secure connection.
Tools Required
To remove PEX fittings, you’ll need the following tools:
- PEX fitting removal tool (crimp ring remover or collet removal tool)
- Adjustable wrench
- Utility knife or razor blade
- Pliers (optional)
Step-by-Step Removal Process
1. Identify the Type of Fitting
Determine the type of PEX fitting you’re dealing with. Crimp ring fittings have a metal ring around the fitting, while collet fittings have a plastic collar.
2. Shut Off the Water Supply
Close the main water valve to prevent water from leaking during the removal process.
3. Depressurize the System
Open a faucet or spigot downstream from the fitting to release any water pressure in the system.
4. Remove the Crimp Ring (Crimp Ring Fittings Only)
Use the crimp ring removal tool to squeeze the crimp ring and slide it off the fitting. Be careful not to damage the PEX pipe.
5. Remove the Collet (Collet Fittings Only)
Use the collet removal tool to pry the plastic collar off the fitting. You may need to use pliers to assist in pulling the collet free.
6. Cut the PEX Pipe (Optional)
If the fitting is damaged or cannot be removed, you may need to cut the PEX pipe. Use a utility knife or razor blade to carefully score the pipe and snap it apart.
7. Remove the Fitting
Once the crimp ring or collet is removed, pull the fitting off the PEX pipe. If it’s stuck, gently tap it with a hammer or use pliers to pry it loose.
Tips for Removing Stubborn Fittings
- Apply a penetrating oil to the fitting to loosen it up.
- Use a heat gun to gently heat the fitting, which can expand the PEX pipe and make it easier to remove.
- If all else fails, you may need to use a pipe cutter to remove the fitting.
Reinstalling PEX Fittings
Once you’ve removed the old PEX fittings, you can install new ones. Follow these steps:
- Insert the new fitting onto the PEX pipe.
- Use the crimp ring removal tool or collet removal tool to secure the fitting.
- Turn on the water supply and check for leaks.
Safety Precautions
- Always wear safety glasses and gloves when working with plumbing tools.
- Be careful not to cut yourself on the PEX pipe or fittings.
- If you’re not comfortable working with plumbing systems, it’s best to call a licensed plumber.
