    When I see traps like that I tend to blame the roofer ..... last year I caught one in the act of removing the trap from a rtu drain as he was also on site because of a water leak. Said "I'm just helping you out because someone installed the drain wrong"

    I used to PM McDonald's cooking & refrigeration equipment. As a favor to them, I'd also remove & flush their RTU traps because they'd often grow a blockage.
    I never understood why their maintenance guys saw some reason to go and plumb all their three or four RTU condensate drains together, then run it all through a common PVC pipe to the edge of their flat roof.
    Are they afraid to get their roof wet?

    I often see that too where they go through a lot of trouble and pvc material of piping an elaborate draining system on the roof to expel the water into a rain drain or close to it. I often scratch my head of what's the point?

    Maybe I misunderstood what you were intending but the point is that you are not supposed to drain RTUs onto the roof.

    Well if so that seems to be a vastly loose and rather pointless code if there is such one. Which if there is it is obviously often overlooked or not cared about.

    nothing more annoying than glued traps and lengths of pvc ran across roof tops. I'm lying, it's even more annoying when the idiot glues the trap to the length with no way to clean it out

    In my area they will nail us if we don't drain off the roof.it also has to drain into dirt and cannot cross concrete. several times we had to drill thru concrete to pass.

    THAT right there is nearly one of the most absurd things I've ever heard!

    What do your local laws say about what a bear CAN do and CANNOT doo (ya knew?)...in the woods?

    That would be about $10k worth of piping on a big roof. We only see them not draining on a roof when the roof is crappy.

    If you think about it; months of summertime condensation on a roof would grow some slime then the tech walks on it slips and breaks his arm or worse, would be reason for a proper drain line - correct?
