Tying In The New Plumbing

This time, the dirty work: cutting out the old drain lines and tying in the new ones.
I used a zipcut blade to cut the cast iron and it worked a lot better than I expected. There are expensive ( or more) sawzall blades that are made to cut cast iron, but from what I’ve seen, these do not last long.
Those of you who are thinking that there is a danger of explosion from the sparks are forgetting that the entire system is vented, and there can’t be any concentrated buildup of methane gas. Also, properly functioning septic tanks do not produce significant amounts of methane gas. No fuel, no fire.
