Review on Camco 21013 RV Straight Swivel Stik with Shutoff Valve - Powerful Waste Deposits Cleaning Action, Odor Control (40094) by Michael Gupta

Quality materials and design make this model a great value. The nylon ball valve and high-impact hose connector ensure a tight, drip-free garden hose connection. The "business end" features a machined brass dual atomizer that spins at high speed to produce a powerful stream that blows around all corners of the tank. I emptied a 2/3 full black water tank that was well maintained and was amazed to see how much debris had been removed from the outskirts. The third flush left the tank almost intact! In the past, I have occasionally flushed the tank with a spray head with my garden hose on "jet", but without this effect. The only downside is that the clear tube is (inherently) flexible which allows the bait to knock against the inner walls. I intend to add 12 gauge 15 inch copper wire (drawn from Romex scrap) to wrap the pipe on the outside for extra rigidity.
