Q:
Is it possible to reduce the pressure at the bottom of a tank full of water by attaching for example a 4" diameter 2' long pipe to the top of the tank and then placing a vacuum on the pipe from the top until water displaces the air volume in the pipe?

A:

Sure, you'll slightly lower the level of the water in the tank. The part in the tube, at a higher level, has reduced air pressure above it, so that is also consistent.
