Cleaning copper pipes before installing compression fittings ensures a secure and leak-proof connection. A clean pipe surface allows the compression ring to create a proper seal. Here's how to do it:
Preparing Copper Pipe for Compression Fittings
-
Initial Cleaning: Begin by wiping down the copper pipe with a damp cloth. This removes loose dust, debris, and any existing coatings that could interfere with the seal.
-
Abrasive Cleaning (if necessary): For heavily soiled or oxidized pipes, use a Scotchbrite pad or fine emery cloth to gently clean the pipe's surface where the compression fitting will be applied. This step is crucial to remove any imperfections that could prevent a proper seal. Ensure the pipe's cross-section remains undamaged.
-
Paste Method (optional): For stubborn stains or oxidation, a paste of lemon juice and baking soda can be applied. Gently rub the paste onto the pipe with a soft cloth, then rinse thoroughly with clean water and dry with a soft towel. This is a gentler alternative to abrasive cleaning.
-
Final Inspection: After cleaning, inspect the pipe for any remaining debris, burrs, or damage. The surface should be smooth and clean.
Important Considerations:
- New Pipes: New copper pipes typically require minimal cleaning, often just a wipe-down is sufficient.
- Old Pipes: Older pipes may have oxidation or other buildup, necessitating more thorough cleaning.
- Compression Fittings: Always use new compression fittings and ensure they are the correct size for your pipe.
- No Sealant (Generally): While some sources suggest sealant, for new, clean pipes, sealant is usually unnecessary. A clean pipe and new compression fitting are key.
By following these steps, you ensure a leak-free compression fitting installation. Remember, a clean pipe is essential for a successful project.
