The requirement for the air gap on a dishwasher (you could use the same device) is to prevent accidental siphon of the trap as well as to prevent backflow of drain water into the draining appliance (dishwasher or condensate pump). Depending on the actual RH and temperatures involved (and some other factors), that combination may result in sufficient water condensing on the outside of the condensate drain line in that space to cause dripping, wetting, inside the return ducts. Fortunately there's a utility sink directly below it. Tanks 11. I would think you need to look at the bigger picture as to where the condensate drain is connected. If you're getting PVC pipe joint failures most often that's from improper prepping. I have direct access to an exterior wall, and the condensate from my HVAC (right next to the water heater) in fact already had its own condensate drain running outside. While venting is a common best practice, it isn't part of the IMC code. Venting after the trap (like shown on the EZ Trap above) is an excellent idea in most applications because it helps prevent airlock that can occur due to double traps and shared drains.
