As the bladder senses vacuum being drawn into the vacuum bag that it is inside: of, it automatically will draw air in to balance itself, no need to pressurize.: As a vacuum is drawn does the pressure in a bladder need to be pumped : : up? If not do you think I could use an intertube(s)? Thanksahhh, of course. that's simply beautiful. thanks for your help
