Here's a mystery. When hooked up to dock water, potable pumps switched off, I get a steady stream of water pouring out the potable tank vents. A steady stream of water. Stops on closing dock water valve. And, with only onboard pumps switched on, I don't get water coming out the vents. Drawings of water system in manual, not so swell, hard to discern how dock water would continuously overfill the potable tank. Perhaps the dock pressure is enough to pass backwards through the pumps? Or, accumulator tank doesn't function properly on dock water? Not a major issue, nor new, other than a waste of water unless I simply keep the dock valve off. I like dock water when aboard simply to relieve my pumps from cycling while my bridge faucet leaks (replacement ordered).
