    2 year old home and the HP AHU has a running trap just off the unit.
    Then the PVC drain runs to here....

    By code
    Twice the inside diameter above the drain.
    Running trap? What’s the static pressure? Positive or negative pressure on the trap?

    All in all it works.

    Wow! No crawl space to see if pvc continues..? But I guess it better than being drilled through the exterior wall and dripping down the siding or tapped into a plumbing stack! I wished I still had that picture from years ago..they drilled into it and siliconed it into place. Problem was during the heat mode the water evaporated and pulled in the sewer gasses(methane) the whole house stunk really bad..lol

    That is perfectly legal since it's air gaped. I've seen that quite a bit in this area, particularly in slab applications.
