Step-by-step guide: how to bond pex pipes like a pro
What To Know
- Apply a thin layer of PEX primer to the inside and outside of the cut end of the pipe.
- Apply a thin, even layer of PEX glue to the outside of the pipe end and the inside of the fitting.
- Can I use PEX glue to repair a leak in a PEX pipe.
PolyEthylene Cross-linked (PEX) piping has become increasingly popular in plumbing systems due to its durability, flexibility, and resistance to corrosion. If you’re looking to connect PEX pipes, gluing is a simple and reliable method. This comprehensive guide will provide you with all the necessary steps and tips on how to glue PEX pipe effectively.
Necessary Tools and Materials
- PEX pipe
- PEX pipe cutter
- Deburring tool
- PEX glue
- Primer
- Clean rags or paper towels
- Measuring tape
- Pencil or marker
Step-by-Step Instructions
1. Measure and Cut the Pipe
Measure the length of pipe you need and mark it with a pencil or marker. Use a sharp PEX pipe cutter to make a clean, perpendicular cut.
2. Deburr the Pipe
Use a deburring tool to remove any burrs or sharp edges from the cut end of the pipe. This ensures a smooth surface for gluing.
3. Apply Primer to the Pipe End
Apply a thin layer of PEX primer to the inside and outside of the cut end of the pipe. This helps prepare the surface for bonding.
4. Apply Glue to the Pipe and Fitting
Apply a thin, even layer of PEX glue to the outside of the pipe end and the inside of the fitting.
5. Insert the Pipe into the Fitting
Insert the pipe into the fitting, twisting slightly to distribute the glue evenly. Hold the pipe in place for a few seconds.
6. Wipe Away Excess Glue
Use a clean rag or paper towel to wipe away any excess glue that may have squeezed out during insertion.
7. Allow the Glue to Cure
Allow the glue to cure for the recommended time specified on the product label. This typically takes several hours or overnight.
Tips for Success
- Use only PEX-specific glue and primer.
- Ensure the surfaces are clean and dry before applying glue.
- Apply a thin, even layer of glue; too much glue can weaken the bond.
- Hold the pipe and fitting together firmly during the curing process.
- Do not disturb the glued joint until it is fully cured.
Troubleshooting Common Issues
- Leaking joint: Check if the surfaces were properly cleaned and prepared. If not, remove the glue and start over.
- Pipe not fully inserted: Ensure the pipe is fully inserted into the fitting until it bottoms out.
- Glue not curing: Check the expiration date of the glue and ensure it has been stored properly. If necessary, replace the glue.
Additional Considerations
- PEX pipe can be connected to other materials, such as copper or PVC, using transition fittings.
- PEX glue can also be used to repair small leaks in PEX pipes.
- Always refer to the manufacturer’s instructions for specific glue and primer requirements.
Wrap-Up: Master the Art of Gluing PEX Pipe
By following the steps outlined in this guide, you can confidently glue PEX pipe and create strong, durable connections. Remember to use the proper tools and materials, follow the instructions carefully, and troubleshoot any issues promptly. With a little practice, you’ll become proficient in this essential plumbing skill.
Questions You May Have
Q: Can I use regular PVC glue on PEX pipe?
A: No, PEX requires specific PEX glue designed for cross-linked polyethylene materials.
Q: How long does PEX glue take to dry?
A: The curing time varies depending on the glue and environmental conditions, but it typically takes several hours or overnight.
Q: Can I use PEX glue to repair a leak in a PEX pipe?
A: Yes, PEX glue can be used to repair small leaks in PEX pipes. However, it is important to clean the area thoroughly and follow the manufacturer’s instructions carefully.
