Old and new in basement. Thoughts please.

I'm getting ready to install a bathroom in a 1950s era basement. Here is what I'm dealing with. The basement originally had a bathroom which was torn out and someone filled the toilet drain with concrete. No big deal to me. The toilet isn't located where I would like it anyways. I want the bathroom to be on the other side of the main stack than where it is now.

I plan to cut out a large rectangle from the basement floor and install the toilet and shower plumbing. I need to tie into the old stack which is black pipe. This is where I'm a little lost. How difficult would this be to tie into the stack? I don't know what kind of problems I'm going to run into with PVC to Black pipe and I'm not sure about the interference of the old toilet's tie in. Would I be better off completing the prep and hiring a plumber to complete the remainder?

Contact the plumber first, have them mark out the floor where it needs to come out, then have them back to rough this in for you.

I'm more inclined to complete this myself. I've done a lot of rough-ins before, but I've never dealt with old black pipe plumbing.

I can only imagine what you're pipe layout is without pictures. Tying into the stack is relatively easy but I'm thinking you want to tie in below the floor. Position the wye where you want it and use a pair of cast iron pipe cutters(available to rent)to snap the pipe. Use no-hub couplings to join the wye to the pipe.
If you could upload some pictures we'll walk you through it.

No pictures yet. Sorry. I don't plan to start this project until next month. I'm in the brainstorming stage. Next time I'm at the house I will snap a few and post them.
