Bleeding water from tanks and guns.

Just wanted to see what others thoughts on this are. Both scuba and SCBA tanks valve assemblies have a tube that extends down into the tank a few inches. This is an important safety feature for breathing use as it prevents any water that might be in the tank from entering the valve and being inhaled by the user. For an airgunner however it is undesirable as it prevents us from bleeding out any water that might collect in our tanks. Removing this tube would most likely cause the tank to fail any visual inspection by a dive shop or other commercial source of air, so that's one potential downside of eliminating it.
It seems that it should also be possible to blast water out of the reservoir of a rifle by orienting the rifle so that any water within it will drain to it's lowest point and then dry firing it to expel it. The exact positioning may vary from gun to gun, but it seems that if you were to store the rifle overnight so that any moisture in it would collect where the valve feeds from and then dry firing the rifle while retaining it in that position should expel any water in it that has collected.
