I have a plumbing code question that I am having a difference on opinion on with my local building department. One inspector signed off on this arrangement and then another later on has told me that it is not code compliant They are not going to make me change it, but we have continued to debate the legality of it.
I have a basement plumbing arrangement almost exactly like the one shown below except that it is under a slab and it discharges straight into a sump basin in the basement about 25' away. The 3" closet vent will have a clean out and then reduce to a 2" individual vent.
The inspector says that it does not meet code in California because the clean out does not come at the uppermost terminal of the building drain.
I contend that the everything from the vent/clean out combination back is a branch line and that as long as it is shorter than 5' than this arrangement is code compliant. I base this on if I had simply wye'd off before the vent creating a branch than it would have been compliant, which seems like the exact same arrangement that I have now.
You guys are much smarter than me on plumbing codes, so does anyone have an answer to who is correct.
Thanks.
