The weight working on the piston is proportional to the area of the piston. It does not matter how much larger or smaller the pipe leaving the piston chamber is.

So the weight of the 4 inch wide column of water (100 ft. tall) in the drop pipe isn't creating downward pressure on the piston? The piston pushing the 2 inch cylinder of water into the 4 inch drop pipe above only has to move the weight of the 2 inch portion? There is no check valve between the 2 inch cylinder and 4 inch pipe. I've attached (I think) a crude drawing of what I'm planning.

Thanks again,
