Hello,
People always say that you shouldn't submerge an unpressurized regulator (first and/or second stage) for soaking after dives, and that it should be attached to a cylinder and be pressurized..
But still, the majority of technical divers regularly do valve drills, including myself. That means breathing the hose dry before switching to backup and so on. During this sucking the hose dry-moment, the first stage of course becomes unpressurized, and most often the first stage becomes a little loose on the valve (meaning it shouldn't be able to safely form av protecting seal at depth during that moment?)
Could somebody explain to me the risks and effects to the first stage during above?
Thank you
