Help: Leaking Drain Pipe On Side Of Furnace

I'm far from a heating pro and have a question. I found the pvc drain pipe leaking right where it connects to the furnace (see pic). My furnace is an American Standard Freedom 80 installed in May of 2000.



The leaking point is the plug just right of where my drain pipe comes out of my furnace. I'm not sure if it's a plug or not, it's just what it looks like.



Do I need to just buy a new one and install it or is it something more complex???



Thanks,



Jed

    Drain

    That is the condensate drain for the AC coil. It can be backing up and partially or fully blocked. It's just sprinkler pipe PVC. Cut it, clean in both directions, glue a coupling on it, done. You can try using a shop vac to suck it out but I use compressed air and blow them out. Common issue.
    Working on steam and hot-water systems isn't rocket science....it's actually much harder.

    Agree with Timco

    It's probably clogged right where the PVC adapter comes out of the AC drain pan . I'd also suggest adding a union there to make cleaning the drain line easier  .

    drain

    I agree with all, you should also clean drain pan,  there are products available to put into the pan to lesson future clogging ( pan pills ).  Check the equip. install instruct. and see if this equip requires a trap

    Coil

    Best approach is to clean the pan, drain, and COIL. Lowes sells coil cleaner, I forget if it's indoor coil approved. If its never been opened or cleaned, do yourself an hour or two favor and check / clean your A coil. Access door comes off front of insulated box then an access door to see into the coil. You'd be surprised at what I've found in there. Sometimes solid sheets of dog hair or big yellow stains from smokers.
