Cut Pipe to Length — Cut and Remove the Damaged Section
Part of project
How to Replace a Cracked Section of Cast Iron Drain Pipe with PVC · Step 4 of 10
In this video
The process begins by cutting the metal pipe to the required length. A manual pipe cutter is placed on the pipe. The handle is turned to tighten the cutting wheel against the pipe, and the entire tool is rotated around the pipe's circumference. This process of tightening and rotating is repeated until the pipe is cleanly severed. After the cut, the manual cutter is removed from the pipe.
Goal: Prepare pipe for threading
- For a clean thread start, it is recommended to deburr the inside and outside edges of the cut pipe using a deburring tool or file.
Used in this video
- Manual Pipe Cutter (Pipe Cutter Type: Manual pipe cutter) — Cutting the metal pipe to the correct length.
- Metal Pipe (Material: Metal) — The workpiece being threaded.
- Gloves (Insulation Type: Insulated) — Protecting hands from sharp edges and tool operation.

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.
