HI, I put a new bathroom into my basement, we know now where the sewer line is to connect the pipe to for the drainage, but is there something special to do when connecting abs to the old steel stack so that the stack won't move or break?

There is a lot of stuff you need to be concerned with when working with cast iron plumbing... so glad you asked!

This link is 3 pages long (81 posts and continuing) and basically covers all phases of a basement bathroom (at least up to point of putting shower in).

If you have any questions after that please come back to this thread and let us know.

Glad to help!
