draining attic a/c, dehumidifier
Apologies for demonstrating the breadth and depth of my ignorance….I’d like to install a high-efficiency dehumidifier in the attic to dehumidify bedrooms (cut down on use of AC in humid-but-not-hot summer nights). This can potentially produce 100 gals/day (Santa Fe dehumidifier) so I need somewhere to send that water. Obvious candidate is wherever air handler sends water….?
I’m blushing as I admit that I do not know how an air handler gets rid of condensate in an attic. In my case there’s a drain pan and a PVC hose going to outside gutter, but I was advised that this is backup only and call the techs if I see any water coming out of there.
In any case I don’t like the air leakage through that pipe to outside. I also learn that condensate is highly corrosive since it picks up copper ions from the coil, so draining it into the gutter system would not be a good idea.
So I am thinking of a 1″ PVC DWV line down to the basement, either into the drain line to the sewer (worries about corroding CI sewer line) or into a sump pit. And a vent pipe up through the roof. And a U-trap (?) to stop air leaks.
Does anyone do it this way say in new construction?

It can either drain outside somewhere or go into a plumbing drain.
If a plumbing drain is used then there would be a "standpipe" somewhere, similar to the unit behind a washing machine, with a hose/pipe from the AC running into it.
If the drain is outside somewhere you'd notice the lush weeds growing in the damp soil.
happy?
Don't worry about the cast iron it is still the best stuff used & lasts the longest.
OK OK I know------- here is the exception photo labs & chemistry labs other than that it's the choice of the pros.
