    Flow out Secondary Condensate Line

    Condensate is flowing more out of the secondary drain on our newly installed air conditioner coil than the primary. A trap is installed on the primary & the line is clear to the outside drain (we poured water down it to verify). No trap is installed on the secondary drain. We have the secondary drain line going into a bucket temporarily so we can easily see how much water drains fm it. The coil is level in direction of airflow (but tilts down in direction of drains in other direction, but I doubt that matters). The primary drain is the first one in direction of airflow, right? What could the problem be? Thanks for any help!

    No way for us to tell without seeing it, call your installer back

    Why not ask the installing contractor these questions?

    The primary drain would be the "lower" one, no matter what it's positioning to the airflow.

    If the primary drain is not visually lower, then there is a dam ring (not a damn ring) at the opening of one of the drains that won't allow condensate into that line unless the primary drain is backed up.

    It sounds like the drains may be mixed up. You should never have condensate draining from a secondary line unless there is a problem with the primary drain.
