I have a Jabsco electric head on my 2005 2900 coronet. The bowl fills over time to the point that it splashes over in 2-3 ft seas. I evacuate the bowl to a very small volume after use. I assume that there is a valve that I can close to prevent the bowl from filling, but it is not apparent to me. Please offer advice...
