Lets get this straight once and for all.
You can’t just use AAV’s everywhere without having one vent pipe/stack to the exterior…OK?
"Because the AAV will not provide relief of positive pressures, there are certain installation requirements specified in the International Plumbing Code (IPC) to relieve positive pressure. The one open pipe vent required on every building drainage system in section 918.7 of the IPC and section P3114.7 of the International Residential Code (IRC), Vent Required, and section 904.1 of the IPC and section P3102.1 of the IRC, Required Vent Extension, mandates that at least one vent pipe shall extend to the outdoors to relieve the system’s positive pressure.
