Another question regarding our new house..When the AC guys installed the
furnace/evap in the attic, we had noticed the condensate drain was poking
out thru the soffit right over a deck over the kitchen window..Well not
wanting water dripping all over a deck we asked, and they told us that was
the "emergency drain" for if the primary one plugs it runs out here and code
requires it to be in front of a window so the occupants can see it..Okay
cool...Like that idea..So up in the attic we were one day and followed the
primary drain, and instead of draining it outside of the house like every
other house I have seen, they dropped it down into the bathroom wall and it
appears it is going to be connected to the sink drain..Is this weird, dumb
or a good idea? Just wanted to ask around..As I had never seen this done
before..I do sorta like the idea, as it's so humid here it's always soggy
out where the pipe comes out which is usually at the condenser....
Thanks a million!

I had a central AC installed last summer. The main evap/air handler is
installed in the attic. The condensate drain pipe is tapped into the
vent for the bathrooms as it passes through the attic to the roof.. I
don't know much about CAC, but I didn't think that water dripping into
the vent would be a problem, since rainwater enters the open vent up on
the roof. I don't know about any emergency drain being installed, or if
it is, where it is going. Wherever the drain pipe enters plumbing, it
should eventually run out to the sewer or septic tank.
The drain being in the sink drain is fine, but I would never put one in a sewer
vent and in fact, some codes won't allow it. When or if the trap in the drain
dries out, it can suck gases into the home from the sewer.
