    Default A/C Evap Drain Piping Trap

    Anything wrong with the way this installer provided a trap for the A/C evaporator drain piping? (The stuff growing inside the piping has been noted.)

    Bruce,

    There is no need for the loop in that drain hose. Water does not drain uphill and the loop will be a sediment trap.

    I personally don't care for that type of drain material. It is notorious for catching debris and stopping up.

    The only good about it is you can see the blockage and know you need to replace the hose.

    No vent for his "loop trap", any trap (and I use that term very loosly) seal will be siphoned out leaving no functioning trap. Just bad design in my opinion.

    I'd be more concerned about the notching for combustible clearance or lack thereof. Hard to tell from the photo.

    Good eye, Barry. The floor framing around the stair opening and framing around the stairs had numerous problems. I was focusing the evap drain piping here.

    Bruce,

    What's that switch for?

    Not a "disconnect" for something, is it?

    Okay, but there is a disconnect ahead of it not mounted to the furnace, right?

    Bruce,
    It is my understanding that these drain pipes are required to be hard plumbed and not flex tubing.

    I am interested in seeing the termination of the condensate drain. For what it is worth, I doubt you will find this type of installation described in the manufacturer's installation material.
