how to connect copper pipe to pex?
To connect a copper pipe to PEX (cross-linked polyethylene) pipe, you can use either push-to-connect fittings or crimp fittings. Here’s a general guide on how to do it:
- Measure and cut the PEX pipe: Use a PEX pipe cutter to make a clean, straight cut on the PEX pipe where you want to connect it to the copper pipe. Ensure that the cut is square.
- Prepare the copper pipe: Clean the end of the copper pipe using a wire brush or emery cloth to remove any dirt, debris, or oxidation. The surface should be smooth and shiny.
- Choose the fitting type: Decide whether you want use push-to-connect fittings or crimp fittings. Push-to-connect fittings are easier to install but may be more expensive, while crimp fittings require a crimping tool but are generally less expensive.
- Install push-to-connect fittings:
- Slide the appropriate-sized push-to-connect fitting onto the end of the PEX pipe.
- Push the PEX pipe with the fitting into the copper pipe until it stops. Make sure it goes in all the way.
- To ensure a secure connection, give the PEX pipe a slight tug to check if it’s firmly attached.
- Install crimp fittings:
- Slide a crimp ring onto the end of the PEX pipe.
- Insert a brass or plastic crimp fitting into the end of the PEX pipe.
- Use a crimping tool specifically designed for the size of the fitting to compress the crimp ring onto the PEX pipe. Follow the manufacturer’s instructions for the crimp tool.
- Inspect the crimped connection to ensure it’s secure and properly compressed.
- Test the connection: Turn on the water supply and check for any leaks at the connection between the copper pipe and PEX pipe. If you notice any leaks, make sure the fittings are properly installed and tightened.
Remember to follow local plumbing codes and regulations when working with plumbing systems. If you’re unsure or uncomfortable with the process, it’s recommended to consult a professional plumber for assistance.
