I was going to put a toilet "under the stairs", take the soil pipe through the wall and join it into the existing soil stack, near ground level.
I just read a post on another forum that says:
"If vent (stench) pipe is actually a soil pipe, with existing WC connection above, a ground level branch will probably be in contravention of the building regulations H1, which prohibit branches within a certain distance of drain invert."
Is this true, and what is a drain invert?
