That... doesn't really tell you anything about the condition of the tank.

Also, the drain plug being at the bottom of the tank is no guarantee that the nipple doesn't protrude into the tank. I've tried to draw it, it's hard to explain. If that drawing makes sense, know that this mistake has been made by engineers working for companies who produce compressors. Would you put it past Joe Schmo who ghetto rigged your compressor to make this mistake?
