Not much to it, I guess - the pump head screws on to the valve body in the same direction that the valve body screws in to the stem on the tube; which ever of those two junctions is less tight is the one that unscrews when you start loosening. I'm guessing that a build up of pressure in the pump tube contributes to a tighter connection between the head and valve body, and in that case the bleed system would help considerably, but I don't know for sure.
