Skipper Joker Valve Solution. Since the joker valve is no longer made for the Skipper toilet, we are working around a solution until we can find a source to make the joker valves for us. We use the Groco Joker Valve and the Jabsco Base Seal to extend the rim of the groco Joker. This creates the same diameter as the Skipper Joker Valve. Some castings have the diameter of the joker very close to the same as the housing and it may squeeze in during tightning of the flange. In this case; the other option is to put an inline check valve behind the toilet to prevent backflow. See inline-check-valve for this application.
