I have checked the archives on this problem, but see nothing that anwers my question...Just emptied the head at a pumpout staion on our "new" (84) Cat 30. I achieved a complete pumpout, but notice that after using the head once or twice, and leaving the valve in the "pumpout" position, I come back to the boat a day or two later to find water in the bowl. It isn't seawater, because I close the through-hull fittings every time I leave the boat, so it must be waste from the holding tank. Any ideas on why this occurs, and how it can be prevented? The boat does not smell very pleasant when I return to it.
