I want to replace from roof to basement, the cast iron pipe which was chased out in my bath on 2nd floor. I plan on cutting this pipe in the attic first, then removing it down to basement. I need to use a smaller line then from basement up so that I can hide this run in a wall? What are the minimum sizes for these pipes. |
