Step 3 · Cut and Remove the Damaged 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.

Identify the cracked area. Using a marker, mark two cut lines on the pipe, one on each side of the crack. Ensure the marks are at least 2-3 inches away from the visible damage and any nearby pipe joints or fittings. Install a new blade designed for cutting metal or cast iron (diamond grit or carbide grit is best) into your reciprocating saw. Apply some cutting oil to the blade or the cut line to reduce heat. Begin cutting at your first mark, using firm pressure but letting the saw do the work. The process will be slow, loud, and will create sparks. Once the first cut is complete, repeat the process on the second mark. Have a helper ready to assist in controlling and lowering the heavy, cut section of pipe into a bucket or onto the plastic sheeting.
