How to Use PVC Glue With a CPVC Pipe

You may have a job that requires gluing CPVC pipe.

CPVC pipe has many purposes, including sprinkler and plumbing systems, in combination with copper piping or by itself. Most uses require gluing pieces of the CPVC pipe together. It is important that the correct glue is used and that the pipe is properly prepared for gluing so that your pipe does not leak.

Things You'll Need

• PVC fittings
• PVC glue or cement for the type of pipe you are using
• PVC primer
• Clean wet cloth
• Clean dry cloth
• Saw or plastic pipe cutting tool
• Sand paper (optional)

Instructions

1. Prepare the pipe for gluing pieces together by making certain the cuts are as straight as possible. Remove all burrs from the pieces of pipe with sandpaper if necessary. Fit the pieces together to make certain you have the correct fittings and measurements before you begin to glue them.

2. Clean the portions of the pipe you will be gluing with plain water and a clean cloth, making certain to dry inside and out. Spread primer on both the pipe and the pipe fitting where they will touch each other when joined. Let the primer dry for a few minutes.

3. Spread PVC glue over the primer and push the pieces together. Push the pipe into the connector as far in as it will go. Twist the pipe about a quarter of a turn. Hold the pipe in place for a full minute so it does not pop out.

4. Let the glue dry for at least an hour (or as indicated on the directions for the glue) before testing for leaks.

Tips & Warnings

• Not all plastic pipe requires primer. CPVC pipe does

• General PVC glue or cement is used for PVC, CPVC and ABS pipe but may not be appropriate for the purpose you are utilizing the pipe for. Check the building codes in your area. For example, general PVC cement utilized on CPVC pipe may not pass inspection for the purpose of transporting water into your home.
