If our solenoid fails, it lets fresh water into the the bowl... but the bowl doesn't automatically drain to the holding tank.
It can if it's a downhill run from the toilet to the tank and the joker valve in the toilet has even a little age on it. How fast the bowl can drain depends on how worn out the joker valve is. Even slow seepage can fill a tank in several days away from boat...a joker valve that's so old the slit has become a hole can do it in hours.
Hmmm... I can envision that... but then our hose from the bowl starts with an overhand loop from the motor... and then it's a downhill-then-uphill run to the tank... so I guess that's never happened in our case. Maybe it could, if left on its own for a longer period...
