I have a house built in the mid-1980's. The main sewage line is cast iron and under the basement concrete floor. The basement bathroom only has sink and toilet drains. I wish to add plumbing for a shower drain. I am nervous to break the concrete and cut into the main sewage line, especially since it is an old cast iron pipe. I feel like there's a chance the pipe might crack, but a couple plumbers have assured me this sort of project is very common. Since I have purchased this house, almost every contractor who said "Don't worry, we do this all the time" has had to come back again and again to fix their work. For something of this magnitude, I thought I'd ask advice here before I continue. What are the chances of complications? E.g., what are the chances the sewage will back up and flood the basement if something goes wrong? We really want the shower there and now's the best opportunity to put it in since we are in the middle of a complete refinishing of the basement. Thanks for any feedback.
