Arcadia Headlining Replacement
WHile it does not show the pipe routing, here is the article on the jeanneau owners site of my head redo. You can see on the back wall a slightly triangular black part. That is my manual pump to pump the tank overboard. The actual tank is behind this wall in the cockpit locker. Then it becomes a matter of getting the approx 2" hoses from the head to the tank to the pump and overboard. Or fit a Y with in the cabinet, then a pipe to the overboard valve.
