How to Use PVC Glue on CPVC
Polyvinyl chloride (PVC) and chlorinated polyvinyl chloride (CPVC) look similar to each other; however, CPVC piping withstands hotter liquids and higher pressure than PVC pipes. It is important to use the correct glue for joining any type of pipes. When working with CPVC piping, use multipurpose PVC/CPVC glue or a CPVC glue; glue made specifically for PVC will not hold properly on CPVC and could lead to leaks or breakage.
-
Cut the CPVC pipe to size with a fine tooth saw.
-
Sand the rough inside edges of the pipe with sandpaper. This allows for a more snug fit, and limits clogs inside the pipes.
-
Dry-fit the pipe and the joint so you ensure the joint is at the correct angle. Mark a straight line across the pipe and onto the joint.
-
Swipe the outside of the pipe and the inside of the joint with an even layer of CPVC primer; this allows the glue to set better between the pipe and the joint. Allow the primer to dry for about 10 to 15 seconds.
-
Apply an even layer of the PVC/CPVC glue over the primer on both the pipe and the inside of the joint. Quickly twist the joint and pipe together until the lines match; hold it together for about 15 to 20 seconds until the glue sets. Follow the glue manufacturer's instructions for wait times before putting water through the pipes.

Tips
- Wear gloves and eye protection when applying the primer and glue.
Warnings
