For this job, the customer had a piece of zinc tubular going into a lead pipe, following that it went into a cast-iron pipe. The customer has tubular for their waste and overflow for their tub rather than PVC so therefore I had recommended for us to cut the cast-iron pipe at the bottom so I wasn’t cutting lead and added a new band at the bottom connected to 2 inch PVC reduced down to inch and a half and then install a trap adapter with a tubular extension piece at the top made sure everything was tight before running water. There are no leaks on the glue fittings and or tubular fittings. I do recommend a full cast-iron re-pipe up to the sewer line to ensure that it is proper flow, but more importantly, all brand new with that in mind I had recommended an estimate for him. We would have to dig in the crawlspace and re-pipe the drains under there and dig outside to find the sewer line.
