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
The washing machine discharge should be connected to that pipe. I'm not sure
what you mean by directly. There must be a "trap".
I have one of these http://www.oatey.com/quadtro.html that the hose hangs on
then there is a standard trap below...
See how it was installed

See the trap, near the floor, then the vent going out the roof.
You should find other connections to it somwhere along the line. It'd
be odd to have a stack pipe for just one drain.
Yeah--I can't imagine venting hot moist dryer exhaust into the stack
pipe would be a good thing. If I were a betting man I'd say it'd be a
big steaming code violation, and possibly a fire hazard to the dryer
