-> being equal, it seems that any amount of pumping action would move
-> the water no matter how high you are above the equal static levels.

 I understand this IF you're pulling the water up a pipe. One
atmosphere can push only so many ounces of water only so far.
 But, if you're PUSHING the water up, you can supply MUCH more
force than one atmosphere. Just ask someone on the top floor of a
skyscraper. 
 Later.
