Appearances can be deceiving <g>

Suppose the spout were attached to a pipe going to the bottom of the 
tank. When the water level is higher than the spout, the system works as 
expected. However, once it starts, and the water level falls below the 
spout, you have a siphon capable of emptying the tank without pumping. I 
have no idea whether they did this, but someone on this list might?
