How to plan a rough-in for LR tub with AAV
Thank you, you folks have helped me and it was nice to go to the permit office and see they agree with my plan. Nothing like having a plan and feeling like you are driving.
Ok, Question. Does my diagram for rough-in LR tub with a WM drain/AAV valve consistent with good practice?
My diagram shows a 2x2x1.5 Tee for the tub. The tub Tee is below a 2x2x2 WM Tee.
The WM Tee has a dedicated AAV.
Where does the AAV go? And now I wonder, will the inspection require a rough-in for the AAV? (or require another permit to add the AAV). I am hoping to just stub off the 1.5 inside the wall).
