I'm not an engineer, but I play one at work
Hey,
At my tract home, I have a ridiculous number of penetrations through my roof deck. Most of these, of course, are plumbing/sewer vents. Several seem to be of the 2-inch diameter sink drain variety.
Anyhow, my boss is remodeling his house and ended up with several "sure-vent air admittance valves" for 2-3" PVC pipes. (Air goes into the pipe when needed but not out)
I didn't know about these, but I understand the thought is that you put these in your attic so that you don't have to go through the roof deck.
I'm about to drop a chunk of money to put on a new roof, primarily because 2 of these vents currently leak. If I can eliminate those penetrations I would like to but not sure where to look for code direction. figured I'd ask you guys.
TIA
