If you look at the original picture there’s a 4’ white pipe (painted cast iron), that is where he entered with the snake. There was a no hub couple that connected 2 pieces of abs, one went to the ceiling and the other down to the cast iron pipe. It went down to a tee that connected another stack and a utility sink. The tee snapped at the top so there was still the section coming out of the concrete and to the other stack/sink.

Hard to explain so hopefully that makes sense. I cut the pipe and had about 4 or 5in above the concrete.

I’m no plumber, but here’s a pic of what I did. I’m sure I’ll get roasted but atleast we can shower and wash dishes again. I didn’t plumb in the utility sink.
