Hello,
I'm planning a bathroom renovation of an ensuite in a dormer loft conversion.
The shower and basin waste feed into the same waste pipe. This pipe currently runs above the floor (boxed in along the bottom of the wall) and then exits the back of the dormer, runs along the outside of the dormer wall and then joins the main soil stack.
In the photo the waste pipe is the white pipe leaving the back of the dormer.
We want to move the waste pipe underneath the ensuite floor.
As this will involve moving the pipe exit to a lower position on the dormer wall, are there any recommendations on how this new pipe should join the soil stack?
