Connecting plastic push-fit fittings to copper pipe involves a straightforward process, often demonstrated in plumbing tutorials. The core steps are to ensure the copper pipe is properly prepared and the push-fit fitting is securely attached. Here's how:
Steps to Connect Plastic Push-Fit to Copper Pipe:
-
Prepare the Copper Pipe: Clean the end of the copper pipe thoroughly. Remove any burrs or sharp edges using a deburring tool or fine sandpaper. This ensures a smooth, clean surface for the push-fit fitting to grip.
-
Measure and Mark (Optional): Although the video states "I won't bother doing a mark," some plumbers prefer to mark the insertion depth on the copper pipe. This helps confirm the fitting is fully seated. Check the push-fit fitting manufacturer's specifications for the correct insertion depth.
-
Insert the Copper Pipe: Push the copper pipe firmly into the push-fit fitting. You should feel it pass through the internal grab ring and seat securely.
-
Secure the Fitting: Once the pipe is fully inserted, it should be locked in place. Give the pipe a gentle tug to ensure it's secure.
-
Tighten (If Applicable): Some push-fit fittings have a tightening nut. If yours does, tighten it according to the manufacturer's instructions. The video suggests this is a crucial step after the initial push-fit connection.
Removing the Fitting:
Push-fit fittings are designed for easy removal using a special release tool. This tool pushes the grab ring back, allowing the pipe to be pulled out.
Additional Tips:
- Always check for leaks after making the connection by turning on the water supply.
- Use appropriate fittings designed for copper-to-plastic connections.
- Follow the manufacturer's instructions for the specific type of push-fit fitting you are using.
- Ensure the copper pipe is round and undamaged for a proper seal. Out-of-round or damaged pipe can cause leaks.
