Soil/waste pipe installation, Scotland

Can anyone tell me should toilet soil pipes vent through the roof or can they be left open in the attic space?

Kind regards
Billy

vent through roof - cannot be left open in attic space unless a durgo valve is fitted - otherwise your house will stink of sewage drain.

Take thru the attic and out any wall, but it must rise 3 ft above any window below it. Durgles are fine in a new space like a cupboard becoming a toilet but if you're going into the attic just carry on, it'll cost about Â£30 more for the right job done right.
