How reliable are the lights in depicting the actual level of the fluid in the tanks (e.g., empty, one third, two thirds and full). I think the sensors in the holding and grey water tanks might be stuck, because on our last trip, they both starting showing a third full after I emptied the tanks and flushed the black water tank. I tried leaving a few gallons of water in the tanks while moving a couple a hundred miles and got the same result. Is there some additive I can use to unstick the valves (we use the standard chemical treatment now in the black water tank). We've only got a couple of thousand miles on the trailer, so I was kind of surprised since everything else (except a shade) works so well. Thanks for any suggestions.
