Well, maybe if they are draining from the top water, the heavier objects will stay near the bottom and the water gushing will be just water. Like an aquarium. Just a thought.
Plus with your thought in mind, surely the pipes would clog up, be hindered if something of significant size tries to flow through the running hoses. I'm with SS, they probably have a screen on the intake/outtake at the beginning, so as to not allow it to go further down the hose causing damage. So in other words, think of it this way visually. THe hose picking up the evidence versus a hand or hand held tool or devise to retrieve it from the lake bed floor. No difference, probably just as safe to dis-lodge an item from the floor with air pressure force versus a gloved hand or tool. Am I making any sense? Anybody? :angel:
