Guide: Field-Cutting of PVC Pipe

Posted By John Houle on May 2, 2018

Installers have been cutting PVC pipe successfully for many decades. However, with the recent availability of PVC sewer and water pipes in sizes up to 60 inches, it is a good time to review the industry’s recommendations for safe and correct field-cutting.

The problem is that when non-standard methods are used and the process is not done properly, the result can be unnecessary expense due to damaged pipes or leaking joints. As well, proper procedures are essential for worker safety.
