In my kitchen I have two separate sinks. One sink is in the island and the second sink is on the exterior wall under a bank of windows. The kitchen sink under the bank of windows on the exterior wall gurgles only when the dishwasher drains. If I run the water full bore it goes down with no issues, never backs up and doesn't gurgle. Both sinks drain into the same 2 inch abs drain line and neither are vented. I had a new water system installed so that should eliminate the copper corrosion in the future you see.
The dishwasher is a asko 20.3 and I could not find the water discharge rate in gallons per minute.
Here is the setup under the sink with the dishwasher.
This is an S-Trap and it's lacking a vent.
As you can see the drain line is a little weird where it connects to the stand pipe. I am unsure why there are so many rubber adapters there and the drain does not make a loop. It seems there isn't enough dishwasher drain hose to make the loop as well .
Here is a picture of the kitchen for perspective and location reference.
So I can't vent this out the roof without tearing out the kitchen. I don't plan on being murdered by my wife on Christmas so this doesn't seem like a realistic solution. I don't believe I can vent out the back of the cabinet because then wouldn't the gasses go into the window when it is open. It would be around 18 inches or more below the window for reference. Do I put a AAV in like in this picture below?
Is the AAV the proper solution without tearing out the kitchen?
Do I try and fix how the dishwasher drain is connected and eliminate most of those adapters?
Would the AAV eliminate my dishwasher drain gurgling loudly?
Anything I am missing or overlooked?
The soil stack is vented into a 2 inch pvc vent but the soil stack and vent are 15 feet away for reference.
