Toilet Issue

My toilet seems to be getting liquid forced into it when we're not onboard.

This originally only happened during the 2 hurricanes, but now it seems that if we don't get aboard for 2 weeks, when we get back on, the bowl is full.

Just happened again in about 2 hours...

Maybe I have the handles positioned wrong or something.

Pictures attached Showing where they're usually positioned.

That handle is not in the closed position. But the one that will make the bowl full of water is the through hull valve that may be not visible easily.

The "switch" at the top of your photo should be left in the dry position (all the way to the right) when you're done. When did you last replace the joker valve?

Have never replaced it.

The switch should be pointed to bring fresh water into the bowl? Or the opposite?

Opposite of bringing fresh water into the bowl. If you've never replaced the joker valve in the time you've had the boat, I strongly
recommend you do so.
