How to Properly Cut CPVC Pipe

Chlorinated polyvinyl chlorinated (CPVC) pipe is an easy-to-cut material that allows for onsite fabrication without the need for special equipment or electricity. Using only simple hand tools, installers can quickly cut CPVC pipe on-site for proper installation of a FlowGuard® plumbing system.

Cutting CPVC Pipe

CPVC piping can be easily cut with a wheel cutter, a hack saw or other fine toothed hand or power saws. Use of ratchet cutters for new pipes is permitted, provided blades are sharpened regularly. During maintenance or when connecting to an old line, ratchet cutters should be not be used.

A miter box should be used to ensure a square cut when using a saw. A square cut creates optimal bonding area within the joint.

Creating a Clean, Beveled Edge

Burrs or filings left unsmoothed can prevent proper contact between the pipe and fitting during assembly. This weakens the joint and potentially disrupts water flow.

For this reason, burrs and filings should be removed from the outside and inside of the piping. Sand paper is preferred but a pocket knife or file is also suitable.

Also, add a slight bevel on the end of the pipe to ease its entry into the fitting socket and minimize the chances of pushing solvent cement to the bottom of the joint.

Handling Cracked Pipe

Check for cracks or other obvious damage prior to and after each cut.

If there is any indication of damage or cracking at the pipe end, cut off at least 5 cm beyond any visible crack. Move on to joining and complete the installation process.
