I'm installing a few mini-split AC units in my house, and I'm trying to determine the best place to run the condensate line. Right now it's either between running it outside with the line set and tray cable, or sending it down to the basement and running it into the slop sink. Running it outside along with the line set is the easiest solution, but I'm worried about insects, enticed by the water and damp environment, climbing inside the line and either making a nest or coming inside the house. Is this a valid concern? Is there anything I could do to prevent that? Anything I need to consider when placing the condensate line?
This is a gravity drain.
