S Trap conversion - not enough room
A possible &quot;other and better&quot; solution from IPC (which may or may not be what your local code is based on - mine is, but this specific section is then banned in the local modifications) is to increase the size at the downturn - see section 917.
By making the downpipe a size larger than the input from the sink, the downpipe cannot be filled to the point of siphoning. I think 2&quot; is called out in that section as currently written, and your typical kitchen sink is 1-1/2&quot;
However, that may be as much work as just moving the drain connection to the wall, with a vent, which I'd argue is better. Certainly more work than installing an AAV, but I'm biased against AAVs since they are prone to fail, and when they fail, they stink, so I will go to considerable effort to get a real vent in place rather than use one.
For &quot;Tee and AAV&quot;, flip the sink connections so the tailpiece is on the left, into a P-trap, into the side opening of a Sanitary Tee on top of the drain standpipe, and extend the AAV from the top of the Tee up as high as you can get it under the counter. Maintain 1/4&quot; per foot slope on the &quot;horizontal&quot; runs towards the drain.
