I'm going to be pulling out my existing cast iron stack and replacing with ABS, but I'm not sure of how I would connect this to the existing sewer main. The cast iron runs into our concrete floor in the basement, and then to the street. What is the best thing to do in this case? Should I remove the stack as close to the ground as possible and then use a no-hub coupling to join the new ABS to the existing CI, or should I jackhammer out the concrete? Kind of lost here - suggestions?
