How do I know if my tank drain is open or closed?

The Manual does not say what way to turn it and I can't tell by looking at it.


When it's screwed up all the way into in is that open or closed?

Porter Cable tank drain

Good question. Don't know your model of Porter Cable, so I cannot be sure.

The easiest way to be sure is to turn the compressor on and feel if air is exiting the tank drain. If so, rotate the drain knob in the opposite direction.
