How to Replace a Cracked Section of Cast Iron Drain Pipe with PVC · Step 6 of 10
In this video
Measure and cut the PVC pipe on either side of the leak to remove the damaged section. Ensure there is enough space to fit the repair coupling.
Goal: Remove the damaged section of the PVC pipe to prepare for the repair coupling

FAQs
What are the main safety concerns when cutting cast iron pipe, and what PPE should I use?
Cutting cast iron creates heavy dust and sharp shards. Always wear a respirator, safety glasses or goggles, heavy-duty work gloves, and long sleeves to protect against debris and cuts. Ensure the area is well-ventilated.
Is a standard hacksaw sufficient for cutting cast iron, or should I use a different tool for efficiency?
While a hacksaw is listed and can eventually cut cast iron, it is very labor-intensive. For significantly easier and faster cuts, consider renting or purchasing a reciprocating saw with a metal-cutting blade or a specialized cast iron snap cutter.
How can I prevent leaks when connecting the new PVC pipe to the existing cast iron with shielded couplings?
Precise measurement and clean, burr-free pipe ends are crucial. Use the specified shielded no-hub couplings and ensure they are torqued exactly to the manufacturer's recommendations using a torque wrench. Over- or under-tightening can lead to leaks.
How long should I expect this project to take for an intermediate DIYer, and what's the most challenging aspect?
This project typically takes 4-8 hours, depending on access and your experience level. The most challenging parts are safely cutting the heavy cast iron pipe and ensuring the existing pipe is adequately supported to prevent collapse or further damage.
