Are they ALWAYS supposed to have water every second they're running?


What do you mean by running?

if it is empty it can go forever or until the motor eventually wears out.

If it is loaded with garbage, it will eventually plug the drain and
probably bind itself up. The water flushes the ground garbage down the
drain to the sewer.
