Question

vent pipe open in attic


is it OK to leave a vent pipe open in an unused attic (just really a gap between the ceiling and roof, too small to be used) if there is a sizeable side wall grid vent, maybe 4x10" within a foot of it or so? i just don't feel like drilling through the roof and sealing it and all. currently, that's the way i have it (but have not done the ceilings yet) and A) it vents fine and B) does not stink.

thanks

Some of the gases that rise from a plumbing drain vent are flammable. When allowed to escape into free air, the gases remain at a low enough concentration to not ignite easily.

The correct answer is NO!!! It must go outside, wether thru the roof or sidewall. Flat roofs can be difficult to seal, so go thru the side. Gable roof flashing is easy to install and works well.
