i just completed a simple add one sink to an existing six business building where i noticed the vent for the sink didn't make it thru the roof? in fact there were no penetrations of any kind thru the roof in the entire facility. all of the fixtures in this building were vented into the attic and i guess that was good enough for one of the previous inspectors? i told the so called plumber who saw fit to continue the practice that he just got himself a lot of work! he smiled:mrgreen:
