Basement rough in AAV vented system
I am roughing in my in ground plumbing. I'm in Colorado and using 2018 IPC code. AAV's are allowed and are being used all over the house.
I attached a picture of what I have I believe this will fail because my sink which will have the AAV is the most downstream fixture. That leaves me with 2 upstream fixtures and I believe I am only allowed 1 upstream.
I am also a little worried about the lav drain making a 180 but one of the 90s is at 45 so I believe that should be ok
If I tee off the pipe going to the shower and add in another AAV would I then meet code?
Thanks for your help.
