Another example of water moving without electricity is old heating system. Furnace heats water, hot water moves through pipe, transfers heat via radiator to air, gets colder and now cold water density is a little higher, so cold water pressure makes it to return to the heater. This is tricky system which requires ancient skill to design and implement properly, its performance is not very good, so in modern systems it usually is replaced by electric pump with UPS. But some people prefer reliable systems which could work without electricity, so those systems sometimes still could be found.
