Hi,
I have no soil stack on the outside of my house. The waste from the existing toilet (on the ground floor) goes straight down into the concrete subfloor behind the loo. kitchen and sink wastes go into a gully.
I have built a new extension en-suite directly above this toilet, and I'm wondering about waste from the bath/sink/toilet in this room.
can i move the existing ground floor loo forward, run a soil pipe vertically up from the existing soil in the concrete floor through the wall cavity, and then tee the ground floor toilet and the upstairs toilet and other wastes into this?
Could this soil pipe then vent into the roof cavity with an AAV on its end, or would it have to vent outside? I'd rather not vent outside with an open end as if it must be 1m above windows it'll end up about 3m above this part of the roof as I've got veluxes in the roof!
Finally, can anyone tell me if its ok to have bends in the soil stack? Ideally I'd run it to the corner of the building before continuing vertically up through the house.
Many thanks in advance for any advice/opinions!
