Good catch.

12 month warranty inspection. Furnace is in the unconditioned attic. HVAC installer didn’t have the ability to calculate lengths of B vent flue connectors for the furnace.
Solution: Use a piece of aluminum dryer venting to make final connection to furnace. Fortunately this homeowner had his inspection before his first heating season.
It is not it’s just a black fiber on the pipe. The condensation you see is coming from the poorly insulated line set material as it enters the air handler.
Soon this black goop will take over the world and it won’t matter. I stand by my original statement. It was designed as a trap…so I would be thinking drain all the way. Maybe an old dog washing station someone rigged up or a pot sink for a now non-existent greenhouse. The possibilities are almost endless.
As Brian said, it’s a drain regardless if the trap is dry or filled with water. A trap is not a vent fitting. I do understand where you’re coming from.
The trap is dry now. Thus, the fitting is presently acting as a vent, meaning as liquid flows down the main pipe, air will come in this fitting.
If later rain fills the trap, it will cease to operate as a vent.
A plumber will need to determine a course of action: complete it as a vent, or cap it and move on. That in turn will depend on if venting is needed at this location. If it’s used as a P trap, then it also needs a vent.
Absolutely incorrect. If you know anything about vents you’ll know that a vent cannot tie into a drain at a horizontal transition. It is not a vent, it is a dry trap. Thats all I’m gonna say about this subject.
