My Neighbor Has a Drain Pipe Leak in the Wall...Part 2

What happens here

This project details the process of transitioning from an old cast iron plumbing system to a new ABS pipe system within a wall. It involves carefully removing the old cast iron pipe and replacing it with a combination of a rubber doughnut, a new ABS pipe segment, and a no-hub coupling to ensure a secure and leak-free connection. The process emphasizes careful measurement, preparation of pipe ends, and proper sealing techniques.
