Last year I replaced the head on my boat. The new head has a manual pump and is made by Jabsco. Everything was great at first. Recently I have had a problem with water seeping in to the empty bowl. Over the course of a few hours the bowl will fill up. The bowl gets maybe 3/4 full but then no more water gets in. I'm guessing this is because the water level in the tank is then equal to the water level of the boat. I believe the water getting in is from the outflow pipe running from the toilet.
Any suggestions on why the water is seeping in? Any suggested fixes?
Thanks!

I'm not sure why it happens, but in the owner's instructions, Jabsco says that, after you pump the bowl dry, you should flip the black control to the right, and then twist the pump handle 1/4 turn to the left. That locks it somehow, and stops the bowl from filling. Mine actually overflowed once. It never did it again after I started to follow that procedure.

Did you put in a anti-siphon valve inline with the water supply?
I just replaced the old, factory-installed toilet with the new Jabsco.
I have two boats, and I also installed the same model of Jabsco toilet in the other boat. I also installed it without changing any of the existing plumbing. It has no anti-siphon valve or anti-siphon loop, and, according to the manufacturer's instructions, doesn't need one. The toilet is installed on an elevated platform above the boat's static or heeled waterline. I have sailed the boat on it's ear, and it has never siphoned water.
Even though it's working properly, I intend to install an anti-siphon loop soon. It isn't expensive, and won't be difficult to install, and having it will give me some peace of mind, in case I, or whoever installed the previous toilet, have mis-judged the heeled waterline.

I looked at the installation instructions again, and the first statement on the page says: "Twist ‘n’ lock action safety handle guards against flooding and waste backflow by locking the waste outlet valve shut." Were you using the Twist ‘n’ lock procedure at the time when the bowl filled with water?

Your head is "outflowing" to the sea? It seems to me that could put you in jeopardy in Canada. Are you allowed to have an overboard discharge there?

Mine uses the sink as an airgap. I don't flush with sea water. I just put a little water in the sink and it uses that to flush. If I fill up the sink too much it does start to drain into the head automatically.

Ya, I guess I'm thinking of Ontario, which was across the water from where we used to live.
