A: The white PVC pipe is the primary condensate drain line for the AC unit, it’s terminating in (draining to) the black ABS plumbing drain vent pipe, which is not allowed.
Here’s why: Connecting the AC drain line to the sewer vent can lead to clogging, the vent pipe is designed to vent sewer gases to the exterior. What’s more, connecting the AC drain pipe to the sewer vent can lead to sewer gasses contaminating the AC system and even entering the air flow inside the home. 👎🤢
NCI, for peace of mind.
