Easily cut and connect plastic pipes, including ABS, CPVC and PVC types
ABS, CPVC and PVC are different types of rigid plastic pipes commonly used in residential plumbing systems. The tools and techniques used to cut and prep these pipes are similar, while the types of glue used for cementing vary slightly. This guide outlines the procedures for cutting, prepping and connecting plastic pipes.
Tip: Check the local plumbing codes to find the required pipe type and size in your area.
WHAT YOU NEED FOR THIS PROJECT
• Tube cutters work well on small-diameter pipes, but for larger pipes you should use a hacksaw or miter saw.
• Make cuts as straight as possible to ensure a proper fit.
• For increased accuracy on straight cuts, brace the pipe so that it cannot shift as you cut it.
• Deburr each pipe by using a deburring tool or utility knife to remove burrs or shavings.
• Dry-fit pipes and fittings, making sure the piping run is sized correctly and does not bend or twist.
• For ABS pipes, remove any ink, oil or dirt with chemical pipe cleaner and allow to dry. Cement ABS pipes by coating the surface with ABS cement, pushing the connectors together quickly with a twist until properly seated and holding the connected pipes for 30 seconds to ensure proper connection.
• Cementing CPVC and PVC pipes requires the application of a primer before applying the cement to ensure proper adhesion.
• Wipe away any excess cement with a rag.
