Measure the length of the assembly, and add 1/4 in. Then mark that length on the cast iron with pencil lines, and use zip ties to mark the cut on the pipe.
Use a reciprocating saw with a metal-cutting blade rated for cast iron to make the cut. Seat the saw’s shoe against the pipe, line the blade up with the mark, and begin sawing. Keeping the saw’s shoe in contact with the pipe helps keep the blade square to the cut, and reduces vibration and the chance of kickback. Don’t force the cut; let the tool do the work.
To make the connection, use no-hub couplings rated for your type of pipe. The ones used here are designed to transition from regular cast iron to PVC or extra-heavy cast iron.
Remove the stainless-steel outer banding from the coupling’s neoprene gaskets, slide the gaskets onto each end of the PVC fitting assembly (making sure that the gasket is oriented properly; each end has a slightly different diameter), and fold it back on itself. Then align the fitting assembly with the cast iron, unfold the gaskets over onto the cast iron, and slip the bands over the gaskets.
Drain-Waste-Vent Systems — Although hidden behind walls and in floors and ceilings, the pipes that make up the drain-waste-vent system are essential to a smoothly functioning plumbing system.
How to Hang Drain Line — Chuck Miller presents this reader tip on hanging drain lines in a basement so they are straight, secure, and at the proper pitch.
Cutting and Joining Plastic Pipe — Most drain-waste-vent systems these days are made from plastic pipe as cast iron is displaced in all but high-end construction. Here’s how to work with PVC and ABS plastic.
Had he slid the bands on to the pipe, prior to rubber couplings; then when he installed the wye fitting, and folded the couplings back onto the wye...all he would have had to do was slide the bands over the couplings and tighten them down, instead of taking them apart, and putting back together. Not a big deal, just saves a lot of time ($).
I've yet to come across a decent blade for cutting cast iron. A ratchet cutter is the only thing i've used for thirty years. If there is a proven blade, please specify.
The Diablo Carbide tipped metal cutting blades are fantastic others may be as well but I only have experience with Diablo. John
