OK - Since there was a recent discussion of AAVs, but I am not 100% clear on proper use/installation, I want to double check…
This AAV was on a kitchen sink over a slab (an addition).
The vent stack was at the rear of the home, this kitchen is located over an old garage to the side and enters the soil line just before it exits the home to the street side. (similar to another I saw previously and referred for review since local code may not allow the use of the AAV)
Is this the proper installation? As I understand the AAV operation, it is self venting, activating with negative pressure, so it does not need to be tied into the vent stack - correct?
As you can see from the picture some plumbing work is needed anyway:D , but I would like to know for my own education about this device.
Any and all advice is welcome (I am writing the report now). I will include a mention to verify with AHJ that this device is allowed, but comments regarding the proper installtion would be helpful -thanks!
