I have an electric
(Newport 1600) that was installed by the PO some years ago. It uses fresh water
. Works well, but I'm not sure if one characteristic of the head
is a "feature" or a "flaw."
The bottom of the bowl is just a bit higher than the top of the holding tank
. It's a short (2.5 feet) straight downhill run to the tank and liquids drain right out into the holding tank
(leaving maybe 3/4 cup or less of water
in the very bottom of the bowl). That is a neat feature, except if someone *wants* to put more water in the bowl before doing his/her business to help grease the skids so to speak.
I have no idea when the joker was changed or what condition it is in. I have not replaced it in the 2.5 years I've owned the boat, but have not used the head that much since then. (There is zero smell in the head, so no gases from the tank back up.)
My understanding is that the real purpose of the joker is to keep the water in the drain line from backing up into the bowl--not a concern in my case. But would a new joker valve help keep water in the bowl when desired? Or would it just let it drain out, albeit maybe more slowly than now?
Should I try replacing the joker? Or leave it alone?
