Step 3 · Cut and Remove Pipe Section

This is the step most people slow down on. Take it one move at a time — there’s no rush, and you can rewind the clip as many times as you need.

Measure the body length of the backwater valve. Transfer this precise measurement onto the exposed PVC pipe using a marker. To ensure the pipe doesn't drop or shift after being cut, support it securely on both sides of your marks using pipe stands, wooden blocks, or bricks. Double-check your measurement. Using a reciprocating saw with a blade designed for plastic, or a dedicated PVC pipe saw, make two straight, clean cuts to remove the measured section of pipe. Once the section is removed, use a utility knife or a deburring tool to clean any plastic burrs from the inside and outside edges of the two remaining pipe ends. A smooth, clean surface is essential for a proper solvent-welded seal.
