Im amazed a stuck valve and hose disconnections werent taught in training - i assumed most/all agencies did this. Certainly here its a must-demonstrate skill and you cant be certified until proven you can do it. Most BCs out there dump and fill at much the same speed so a stuck inflation valve the system is to hold open a dump somewhere whilst disconnecting the hose.
Its fairly easy to get crud into a valve and have it jam so its pretty vital to know how to deal with it quickly.
Again, on a drysuit its a thing we trained for a lot even to the point of someone deliberately holding inflate down on a diver with a spare weight belt over him to make him positively buoyant then releaseing the weight. Diver then had to demonstrate manual disconnection of the hose AND dump air before hitting the surface of the 4m pool. Thats a club variation on a theme but ive seen various others do the same.
My one regular buddy has a dry suit inflator that seems to stick on 50% of his dives and no amount of cleaning or spraying seems to stop it. He is not VERY fast as disconnecting and continuing the dive
