Hello experts,
Here's the situation: new build dormer bungalow, five toilets (yes, five - two are for a childcare facility), a black drain pipe at each gable, one of which has a vent, the other curves directly into the wall.
Snagger has said that both should be vented, builder says they're both on the same mains and one is sufficient. Any guidance/advice/opinions?
Thanks!
