Ok, after reading the manual once again, I think I figured the water supply problem. I was thinking this whole time when I have the water hooked up the the back of the boat, it is automatically filling the fresh water tank up. I guess there is a freshwater fill on the starboard deck area that has to be filled. Maybe I used all my fresh water and when i turn off the hose, it doesnt work. I need to fill the fresh water through the deck fill, thought it filled through the supply when i hooked the hose to the boat for water. Maybe this is the problem I am having with the toilet? No fresh water, so it isnt vacuum flushing?
Yes, the shore water fitting only supplies water as a source, not as a fill mechanism. I actually modified my plumbing system to allow filling through it, but that's a bit complicated. For you, yes, you fill the water tank from the fitting up on the bow. When you have the shore water hooked up you should turn off the fresh water pump at the breaker panel.
BE CAREFUL WITH THE HOT WATER HEATER! DO NOT RUN IT EMPTY! It will almost immediately burn out the heating element. Which can be replaced, but it's a hassle to get to it.
Obviously the toilet won't work without water. Given how long yours was sitting I wouldn't make any bets on what shape the parts are in. There are a number of rubber seals. And like anything rubber they eventually have to be replaced.
A common technique for dealing with the waste tank is to dump a bag of ice into it, along with some Dawn dishwashing soap (half-cup?). Then take it out for a run to allow the ice to agitate inside the waste tank and break loose anything that's clumped up in there. The ice will eventually melt to water and can be pumped out as usual. Expect to have to flush the tank several times (but only do the soap once). Have fun tying up the pump out dock for the afternoon!
Update:
it has been suggested to me that ice cubes going through the duckbill valves of the toilet might not be a good idea. So it might be better to try just detergent alone.Once you have the tank flushed to relatively clean water you should use a tank treatment that uses bacteria. And USE the toilet. The bacteria depend on waste solids to do their work. If you're just using it for '#1' then the bacteria won't have anything to feed upon. Do not use any treatments with formaldehyde. If you do you'll have to flush the tank several times again as formaldehyde kills the bacteria (not to mention it's heinously bad for the environment).
In another thread there's been some advice about putting vegetable oil into the toilet to help 'lubricate' the various rubber bits. Seems like a decent idea and worth being part of regular maintenance. But you'll need to get your system cleaned out first.
There's a lot to a vacuflush system but it's relatively simple to troubleshoot. Once you have running water AND you've pumped out the tank let us know what is or isn't working.
