One thing I found is if the other guy actually drags the tube across the top of the sand so you’re getting a constant stream of sand rather than a 3-4” section of sand in the hose and then a 6+” section of air, then the sand, air etc. it works better and you get further with less sand.
The tee-connection where sand is sucked into the nozzle must be kept swiveled ABOVE the nozzle, especially when you stop the water-flow...otherwise, a dribble of unpressurized water that's left in the wand will run right down into the dry sand that's still in the siphon hose and clog it with great regularity. I don't think I'd try to use one of these again without a full-time helper, if ever, because more time was spent unclogging and dealing with wet sand than was actually accomplishing the task at hand.
