I've got a new functional electrical system
and my boat isn't burned to the waterline, so I think I'll venture into really dangerous territory: The head
system consists of a built-in fiberglass holding tank
, an intake throughull/seacock, an empty overboard
throughull/seacock next to the toilet, and a new Jabsco
toilet halfheartedly plugged in. The toilet dumps to the holding tank
, which also has a pumpout hose and a vent hose. The head
is very cramped in this boat.
One option is to figure out how to install a Y-valve and vented loop in the exhaust
hose, and a vented loop in the intake hose. I haven't figured out how to make those fit yet, and don't think it's possible without the addition of a 90* elbow
or ten. This would leave us with no way to pump out the holding tank at sea, but would allow us to pump the toilet directly overboard
. I'm not thrilled about adding connections and fittings, but perhaps that's where we'll end up anyway.
I've also considered skipping the vented loops, and just making head procedures start with "open seacocks" and end with "close seacocks." That would simplify installation
somewhat, minimize breaks in the hose/likely failure spots, and insure that the seacocks get exercised regularly, but at the cost of potentially sinking the boat if we muck it up. (Level waterline is about the top of the bowl.)
An alternative solution would involve a T in the pumpout hose and something like a Whale pump to the overboard throughull. We'd have to pump twice to get waste overboard, but could empty the tank at sea.
Suggestions/cautions/ideas/pictures all greatly appreciated.
