I have noticed a few discussions on this topic, but the typical answers are less than satisfactory to me. In my case, I have two AC air handlers, which are located in the attic, 14-feet above the single-story living space. The condensate lines from each air handler join together into a single PVC pipe that descends down into the drain of a sink in a spare bedroom. This single condensate line enters the sink drain line above the trap and just below the sink itself. I have to say, in hot humid Houston, this scenario is an absolute disaster.
You know what happens next. The ubiquitous ever-present white slime blocks the trap, but the condensate keeps on coming. It fills the sink, overflows the sink, and then floods everywhere. It has destroyed the bathroom cabinet, damaged the drywall and molding in the bathroom, and extended out into the bedroom where is has damaged the molding and carpet. Pouring Clorox down the sink on a regular basis is a no-go because I have a septic system. I have been using a supposedly septic-safe product called Pequa. It works, but so what? I am over inspecting the spare bathroom sink on a weekly basis looking for water and pouring Pequa down the drain. If I go away for the weekend, I am in danger of flooding. In other words, I am tired of covering up what is clearly poor design.
My thinking is to relocate that condensate pipe straight through the wall to the outside where it can dump all that junk on the ground. It might be an eyesore out there, but I can live with that compared to the mess I now have. Does this sound like a reasonable solution to the problem?
