I own a town house and have a small drain (for laundry) located in a first floor utility room. I am trying to vent my dryer and noticed (while opening the drywall up to see what I had) the drain has a vent that goes to the roof (two stories). Its plastic probably about four-six inches in diameter. Is this for sewer gases or something? Is that why it goes to the roof? No other drains are hooked up to it,-- unless underneath they all flow into one-- and that is the vent?? I didnt want to run a seperate vent for the dryer but it looks that way huh?
