    Hmm Existing Condensate plumbing looks wrong - secondary drain pan?

    Hi... I'd like to get some opinions on the existing condensate plumbing and lack of a secondary drain pan under the evaporator plenum:

    What is the lower 3/4" PVC line tied into inside the plenum? A drain pan inside the plenum?

    Is that a cap on the port next to the primary port? Does this port need to be connected to anything?

    I plan on having a large drain pan installed under the evaporator plenum. Should I have the lower secondary plumbing capped off and move to the new secondary drain pan?

    Thanks!!!!!!

    does the lowest one actually thread into the plenum corner or a factory fitting in the coils case? is this located in an attic? of a house?I would get a drain pan installed a.s.a.p. with a drain switch. it looks like there is nothing protecting an overflow do to blocked drain or anything to alarm you of a problem. the pic is hard to see, where does each drain go?

    I would need a closeup pic of the coil model number, or the installation manual page on draining. but the ? Connector appears to be the actual primary connection... Rheem/Ruud coils have a weird triple connection due to multiple mounting positions...

    I also agree, that a backup pan under the coil ASAP is a good idea.

    Do you go to a boat repairman with a sinking boat, and tell him to put in a bigger motor when he tells you to fix the holes?

    Isn't it listed in the manual 2 or 3' of straight duct before any bends or take-offs?

    Wow... I learn something new everyday... this Aspen Mfg evaporator has a built in secondary drain pan under the primary drain pan... how smart is that. I'm going to put a Safe-T-Switch in Primary Line. I can use Safe-T- tool to clean out the primary drain line. And maybe add a Honeywell Water sensor alarm that has a long wire sensor I can stick in the hole next to the secondary pan outlet fitting. At least then if water starts to fill the secondary pan I will know.Name:  ScreenClip.jpg
