Ok Mark, I guess my point is that the above-ground pipe can trap
condensate water even when installed to the minimum slope. I would
agree the condition is much better with ample slope and careful
attention to detail. Specify the ten marble test where ten marbles in
one end exit the other end.

Alan: Just to be clear - this pipe is now being located such that it
drains to a conditioned space below grade (the sprinkler controls
room)
- there will be no trapped water. Therefore it is not different than
above-ground pipe as far as the amount of moisture it will see.
