I'm looking into ways to put en-suite bathrooms into two bedrooms which are room-in-roof (2nd floor). The floor level is above the eaves and the soil stack is on the outside wall mid-way between the two bedrooms.
My idea is to have two 4 inch toilet wastes joining into a vertical pipe which will be midway between the two en-suites and going down inside a new partition wall (extra wide partition wall to accommodate the pipe comfortably) on the first floor. Near the bottom of that wall, the pipe will have a bend and then 2 junctions taking waste from two more toilets on the first floor, then out though the wall to the existing soil stack.
Currently, the only feed into the soil stack is at ground floor level. The stack is cast iron and it's a listed property.
The wall is 800mm thick.
The question is, does building regs allow a vertical section of soil pipe inside the building, before it goes though the outside wall?
