Step 5: Cut the Pipe (If Necessary)
If the fitting does not come off easily and is not designed for reuse, you may need to use the PEX pipe cutter to remove the pipe section attached to the fitting. Cut the pipe as close to the fitting as possible, ensuring a clean cut.
Step 6: Check for Residual Material
Once the fitting is removed, inspect the fitting and the pipe for any residual material, such as pieces of the grip ring or debris. Use a utility knife to carefully scrape any stuck material off of the pipe to ensure a clean surface for the next connection.
Step 7: Prepare for Reinstallation or Replacement
With the old fitting removed, you can now prepare your pipe for either reinstallation of a new quick connect fitting or for whatever new configuration you’re planning. Make sure the end of your PEX pipe is smooth and clean.
Tips for a Successful Removal Process
Removing PEX quick connect fittings can sometimes be a little challenging, especially if they have been in place for a while. Keep these tips in mind:
Use Lubrication
If you find that the fitting is sticking, a little plumbing lubricant can help ease the removal. Apply it sparingly around the fitting to help loosen it.
Be Gentle but Firm
When pulling or twisting the fitting, be gentle to avoid damaging the pipe. However, also apply steady pressure to ensure the fitting does not get stuck further.
Check Compatibility for Future Fittings
When preparing to reinstall or replace your fitting, check the compatibility of the new parts with your existing PEX pipe. PEX comes in different types (A, B, C), and ensuring the correct type will prevent future issues.
Pitfalls to Avoid When Removing PEX Quick Connect Fittings
Removing PEX quick connect fittings can seem straightforward, but several common pitfalls can lead to trouble:
