Just for information, vacuum pumps can't lift water more than thiry feet. So the word pump is irrelevant here, as it is in every large tree.

FYI: Pumps can push water up hundreds of feet if you place them at the bottom of the well instead of the top.

Yes, but they wouldn't be vacuum pumps, would they? Perhaps my terminology is defective.
