Can I vent soil stack from the side instead of the top?
I am working on adding a bathroom to the second floor of my home. One problem I've encountered is that there isn't a wall that runs all the way up from the basement to the roof. Instead, there is a 15" jog from the top of the first floor wall to the bottom of the second floor one (represented by the yellow line in the photo). Fortunately, there is a closet just below, so I can run my DWV pipes into that closet. I cannot vent the stack traditionally though, so I've planned to vent it with a separate 2" pipe that will run from the roof, down the 2nd floor wall, into the closet below and attach to the side of the stack (represented by the red line. Just below the stack vent I plan to place the branch waste line for the shower and vanity (represented by the blue line). Is venting the stack this way acceptable?
