O.K. So I start my inspection and find out it’s flipped house and the owners GC is there following me, and of course he has one of those GC attitudes (that give the other 5% a bad name). And of course we butted heads when I said something about the wood frame/stucco portions below grade (and he says “That’s pressure treated pine, it’s good”) So here are some photos of the condensation drain line termination. I would like something better to write than the usual (poor location, no proper trap at the handler or exterior, ect.).
Yes, it’s a clear plastic hose sticking out of the ground (he told the buyer that he would trim it!)

If it meets the qualifications, they why is it wrong. You say its the right material. From the picture it is improperly trapped and subject to damage. If so, then write that and document why it is wrong. State what you see and know and recommend it be done right - then move on.
No pump, 2 feet down under the handler, under the slab and termination as pictured, slope draining downward until the hose curls up and over forming the “trap”.
Piping material not approved for burial and not protected from deterioration of rocks and chemical reaction by not bedding in sand; double trapping possible if on negative air side of coil?
