Re: Drain line configuration

In the first photo I would say no for reasons I will add to this thread later as time permits. I say no because I think that the air gap Jerry rightfully talks about is indeed present. We shall see if I can convince Jerry of that. He remains doubtful it seems but I remain adamant in this regard. It should be interesting!
In order to do that though, its going to take me some time to atempt to develop a Jerry convincing argument and its already late here tonight. Convicing Jerry Peck to change his mind/opinion is not an easy thing to do in my experience. Subsequently, I will have to get back to everyone later and my work calendar is currently full.
In the second photo I would have to say I don't know because I don't have enough information as yet. In order to say for sure, I would need to know what the observed tubing is connected to before it is connected to the sink drain trap and at what level in relation to the flood rim of the sink in question. Again, this will define whether or not there is actually an air gap present.
Some AHJs do permit a backflow/check valve instead of an air gap but I personally prefer the constant nature of gravity over the mechanical operation of a fallible backflow/check valve.
Jerry,
I will indeed get back to you here in this thread on my reasonsing regarding the presense of an air gap in the piping configuration I presume to exist in Jeff's photo #1.
Such HVAC drain line attachments are very common here locally and are accepted by numerous code authorities. With any luck, I will be able to explain to you why this is so.
