I am adding a new two piece bath. I want to run the vents up to the attic and across to the main vent.
The problem is that there is no way to access the main vent without going down a foot or so.
It would be possible to have the horizontal run of the new vent slope towards where the main vent connection would be. In other words the new vertical run would would go higher up than where it ties in.
Would this cause problems?
It is winter and going straight up through the roof is sort of out of the question.
I'm in a no inspect zone so no help from inspectors, sigh.
