Soil stack ventilation pipe open to air and roof ventilation tile
Posted: Mon Jun 22, 2020 7:20 pm
Building regulations state a soil stack ventilation pipe open to air should finish at least 900mm above any opening into the building within 3m. Does a roof ventilation tile connected to a bathroom exhaust vent extractor constitute an opening into the building? The position of the vent tile is in the bottom third of the roof. Thanks.
