Hi there - I've been reading through your forums for some time now as I work on installing a second floor laundry room and I've run into a little issue where I can't seem to figure out the venting for my floor drain. My original plan was to vent the drain per the attached image (black is drain, blue is vent):
The issue is that my vent stack is offset from the drain stack - through some reading etc I've determined that I can't have a horizontal stretch of venting before I reach a minimum of 6" above the flood rim for the fixture. My solution was to move the sanitary tee directly underneath the vent stack and plumb back to the drain stack (modification in orange, removed washer drain line from drawing for clarity):
The problem I'm facing is that I just don't have enough room for the fittings (if the sanitary tee is too high then my floor drain won't connect to the trap correctly, it needs ~5" of clearance) - the floor is framed in 2x12 lumber so I only have 11" of vertical space. Any help or ideas as to how I can properly vent this floor drain (it will be primed as well).
Thanks so much for your help!
