Connecting PEX (cross-linked polyethylene) pipes is a common task in plumbing, whether you’re a seasoned pro or a DIY enthusiast. This comprehensive guide will provide you with step-by-step instructions, essential tools, and troubleshooting tips to help you connect PEX to PEX pipe with confidence.
Essential Tools and Materials
Before you begin, gather the following tools and materials:
- PEX Pipe Cutters
- PEX Expansion Tool
- PEX Expansion Rings
- PEX Pipe
- PEX Crimp Rings
Step-by-Step Instructions
1. Measure and Cut the Pipe
Measure and mark the desired length of PEX pipe. Use sharp PEX pipe cutters to make a clean, perpendicular cut.
2. Deburr the Pipe
Use a deburring tool or sandpaper to remove any burrs or sharp edges from the cut end of the pipe. This prevents leaks and ensures a secure connection.
3. Insert the Expansion Tool
Insert the appropriate expansion tool into the cut end of the PEX pipe. The tool will expand the pipe, allowing you to fit the expansion ring.
4. Insert the Expansion Ring
Slide an expansion ring onto the expanded pipe. Make sure it is fully seated and centered on the pipe.
5. Remove the Expansion Tool
Carefully remove the expansion tool. The pipe will contract, securing the expansion ring in place.
6. Slide the Crimp Ring
Slide a crimp ring over the expanded pipe and expansion ring.
7. Crimp the Ring
Use a PEX crimp tool to crimp the ring. The crimp should be tight enough to secure the pipe and ring, but not so tight that it crushes the pipe.
Troubleshooting Common Issues
1. Leaking Connection
- Check that the expansion ring is fully seated and centered on the pipe.
- Ensure that the crimp ring is properly crimped.
- Replace the expansion ring or crimp ring if damaged.
2. Difficulty Expanding the Pipe
- Make sure you’re using the correct expansion tool for the size of pipe.
- If the pipe is cold, warm it up slightly with a heat gun to make it more pliable.
3. Crimp Tool Not Crimping Properly
- Inspect the crimp tool for any damage or malfunction.
- Make sure you’re using the correct crimp ring for the size of pipe.
- Adjust the crimp tool settings if necessary.
Additional Tips
- Use PEX-specific tools and materials to ensure a secure connection.
- Always test the connection before putting it into service.
- If you’re not comfortable connecting PEX pipe yourself, contact a licensed plumber for assistance.
