ARRRGGGGHHHH!!!!
Why does everybody think the joker valve is supposed to keep water in the toilet bowl???? [:-banghead] [:-banghead]
The joker valve is a one-way check valve that stops water from returning to the toilet bowl after flushing the toilet, such as when there's a partial clog in the line downstream from the toilet.
In the case of manual toilets, the joker valve works in concert with the flapper valve to direct the flow of water, and other stuff, out of the toilet.
Sometimes, when the joker valve is new - and only sometimes - it will hold water in the bowl after flushing - temporarily.
But that isn't its job, and this added benefit after replacing the joker valve won't last very long.
Marine toilets don't normally keep water in the bowl; they aren't designed for that purpose. As they must be used in all different onboard applications, many of which don't want water to be retained in the bowl, they are designed not to keep water in the bowl between flushes.
Picture yourself being on a boat out in the ocean, bouncing around during a storm, with the water from the toilet bowl sloshing out, all over your brand new teak parquet decking in the head, as an example...
The only sure way to keep water in the bowl between flushes, is to run the discharge hose from the toilet upwards - higher than the top of the bowl - to a vented loop fitting. Then the hose runs back down, to your holding tank, overboard, to a treatment system, or wherever the final destination might be. And that's the only way!
Now, repeat after me: JOKER VALVES DO NOT KEEP WATER IN THE BOWL BETWEEN FLUSHES !!!

Sorry about the rant, but if you'd heard that question as many times as I have, you'd go off, too! Everybody that has any sort of problem at all, always goes for the joker valve first, and it drives me up the wall!
When a manual toilet won't flush solids, it's usually the joker valve, and when you get dirty water backing up into the toilet bowl, it's usually the joker valve. But that's really about it.

After 17 years of the Jabasco electric flush I finally put in a repair kit. It would be hard to get the motor to spin and eventually pop the breeaker. It now runs fine.
When I took it apart, there was no joker valve installed. The kit came with one. Is it always needed or did the manufacture forget to put it in?

As far as I know, the manufacturer always installs one inside the discharge fitting of the toilet. Depending upon the particular installation, they aren't necessarily needed in every instance. But the manufacturer always includes one, simply to avoid a product liability situation if something were to go worng. Also, I'd think the head would leak all over the place if there weren't one installed - the joker valve is also (usually) a gasket between two parts that have water going through them.
