We replaced the original Jabsco manual head on our Hunter 356 in June of 2005 - 2 years after we commissioned our 356. We have been on our boat a total of 1200 days and all but 160 of those days have been with the Raritan Sea Era electric head. It still has the original joker valve, but I have a spare if needed. I highly recommend it. We use normal toilet paper and don’t have any problems with it. When guests are on board, we tell them just “push the black button on the wall until the bowl is clear” ( we had a small sign made stuck next to it for for redundency). No issues from guests who never could figure out how to work the manual Jabsco.
