Re: Drain line configuration
Jerry,
There is indeed an air gap present assuming that the HVAC equipment drain source is located higher (from a gravity perspective) than the flood rim of the sink to which the HVAC's primary drain line is connected.
The second photo? We need to know what the piping is attached to and where it is located in relation to the flood rim of the sink associated with the drain trap in order to render a proper opinion.
