Hey guys, so I am new to kegging, and I am trying to sanitize my keg before filling it up with some yummy stout. I have my connections all right, I know the keg is pressurized, however I'm having trouble getting the sanitized solution to dispense out. When I take the ball lock thing off the liquid out and press my thumb into the little tiny hole, liquid does come out, so I know it functions properly. Just how do I get solution to come out when I press my down on the party tap thing.
Here's a picture.
