Hey guys,
Typically when I am using autoCAD, I use sanitary tees to connect my runs of vent. I was wondering if I could use a flipped figure five to connect two runs of vent on opposite sides of a vent stack. In my picture below to the right is how I have seen a lot of Vent runs connected to a vent stack, but if code permits, and i don't see a restriction in chapter 9 of the CPC, can I use the set up on the left?
Picture is front view of my vertical vent stack.
Any info is appreciated.
Thanks
RR

Yes, a figure 5 or a cross will work in that position.

I see. I have a no-hub san cross in my catalog but i haven't used it for venting because it didn't look like it had branches that bent with flow. So in this case, i'm assuming there should be some bend in the arms, should i flip it and put it on its head like i did with the figure 5 on the vert stack? Here is a pic of what i have in my catalog. It is not flipped in this pic.
Appreciate the help.

Plastic DWV fittings have a LOT of movement in the hubs so they do not have build the slope into them.

Dry vent fittings don't need a sweep in the branch. Vent tees are made that have a 90* no sweep branch.

And, because they have limited demand, compared to sanitary fittings, they cost more.
