Need a second opinion on this AAV installation under this kitchen sink. I think the valve needs to be higher, (I’ve read 6" above trap arm) but their is no arm on this drain! Is the drain completely wrong and needs to be redone with a P trap and AAV? I did not note any problems when running water. I filled the sink and drained it to see what happens and it drained fine.
Yes, that’s an s trap. Needs a do-over.
Yep, what Joshua says, it should be done over.
And if not, then the AAV should be 6 inches above the trap weir
