What is it's function?

Yesterday will addressing black tank overfill issues I took a 2nd look at this thing. Never paid any attention to it before. The line goes directly to the side of the black water tank. A cap seems to be missing. The inside of the end is threaded possibly for the male end of a water hose. I can make a couple of guesses as to its function but I would like to hear it from someone who actually knows. Oh, by the way, it is on a 2004 Keystone Cougar 278 EFS 5th wheel.
