thanks,
Yea, up in my attic there is a large 3 inch pvc pipe that goes up out the roof, its the vent stack for the sewer/plumbing in the house?
there are several smaller pvc pipes that join into it. I am assuming that I can join into that and vent right up to the roof away from any neighbors?
I will be blowing air out it so would I get bad shit smell backup ?
