Joker valve, plus if your vent line is plugged you would be pressurizing
the holding tank when you pump into it.

I have noticed that the water level in the bowl of my head tends to
increase over time. It is not close to overfilling, but when I get to
the boat is is several inches higher than when I left the boat and
after pumping it out, over the course of a day on the water, it is
higher at the end than the beginning even when not used. The through
hull valves are all closed and the pump valve is in the tank/closed
position. I can't see how the throughhulls could be leaking so the
only thing I can imagine is fluid leaking from the holding tank back
into the bowl. The holding tank is under the sink on this boat and so
the fluid level is well above the level of the bowl.
Probably unrelated, but when I had the tank pumped yesterday ( the
new free pumpout boats in our area are fantastic!!), the pumper told
me the vent tube was likely plugged because he got vacuum on the
pumping system. What is the easiest/best way to clean out that tube?
Thanks- Dave
