What is the recommended method for cutting cast iron pipe?

The recommended method for cutting cast iron pipe is to use a ratchet cutter. Ratchet cutters are specifically designed for cutting through tough materials like cast iron with precision and efficiency. They provide a clean cut and are easier to control than many other cutting tools, making them ideal for this heavy and dense material.

Using a ratchet cutter allows for a more manageable approach since they offer a leverage mechanism that cuts the pipe gradually without requiring excessive force. This is particularly beneficial when working in tight spaces or when needing to make precise cuts on existing plumbing. Additionally, ratchet cutters typically leave behind a smooth edge, which is important for ensuring a proper seal and fit when joining pipes.

Other methods, such as using a reciprocating saw or hacksaw, may not provide the same level of control or might produce less clean cuts, which could compromise the integrity of the joint. Similarly, a pipe wrench is not intended for cutting and lacks the necessary power or efficiency needed to cut through cast iron effectively.
