That's not a very nice answer. It's still a sailboat.

If working properly, the manual pump will pump whatever is in the bowl out,
and can also pump seawater into the bowl if desired. My experience is w/ a
newer Jabsco, but should be the same.

Sounds like your pump needs a rebuild kit, also a vented loop in the hose
between the top of the pump and the top of the bowl. I think the lake is
slowly filling your tank all the time.

I just bought a new boat (to me) and have some head questions.

First some info:

Boat - Hunter 34, 1983

Head - Jabsco manual head

Now my problems and questions:

1. My toilet is filling up with water after it is pumped dry. I am
assuming this is fresh water (lake inlet) but am not usre

2. My holding tank seems to be filling up a lot faster than it should.
I have about a 20 gallon holding tank and it is full after a day sail
with light use. Keep in mind this includes a week's worth of sitting
without use.

3. I'm not familar with one part of the unit...Right next to the head
there is a manual pump. A hose comes in through a thru-hull and does a
loop that wraps back through the pump and to the holding tank. Is this
to pump out of the tank to the lake or the opposite?

Any help would be appreciated.
