I recently purchased a Jabsco quite electric head, that has worked fine all summer but recently when you flush it, when the bowl goes dry it splashes back up about a foot. anyone seen this or have any ideas??
run your overboard pump a few seconds while you have water in the bowl.
See if that draws it out or alows it to work. If so be carefull your flexing your tank with every use. If you turn Y valve to deck pipe and take lid off it should work normal if its the vent.
