What you are looking for is the required "Head Pressure". To figure that out, you will need to know the number of turns and T's, the height and the length of the overall pipe.

You can use the calculator on this page to help figure it out.

Here are the actual formulas from The Engineering ToolBox

You are missing a few key parts of the equation.
1. What type of reservoir are you using? Is it a well?
2. What is the diameter of the pipe you are using?
3. How much pressure do you need at the end of the 9 meters?
There are well pumps that will push water 100's of meters but to calculate what you want I need some more info.

When water falls through a pipe, it builds about 0.34 pounds per square inch per foot of fall. So, if you exert that same amount of pressure per foot of fall, it becomes static. In order to push the water up, you must use almost double, or about 0.68 pounds per square inch per foot that you want to push. Now I am not an engineer, but my father was a plumber and made me memorize allot of useless facts. So, in an edjucated guess, and that is all it is, you want to push the water 29.5275' so that if you multiply it by 0.68 then you get 20.08 pounds per square inch. That should do it...If you want an exact, you can go to cr4.globalspec.com, they have a question/answer column that is answered by qualified engineers, they will give you an exact answer. but 20 lbs per square inch should be more than enough pressure.....Thanks Zgrinch

I'm imagining that you are wanting to pump water up to the third floor of an apartment, and looking for practical information regarding the sizing of the pump, as opposed to a pure technical calculation from a physics point of view, which has already been supplied by omicron. I may be over reading your question, but if you would like the smooth flow of water coming out of the tap, then you would need a pump and pressure tank system. Otherwise, the pump would always be on when you need water. The link I am supplying, has a list on the left side, of all kinds of plumbing related topics and how to address them. This particular link addresses the problem of short cycling of the water pump because the air pressure in the pressure tank is insufficient. In the attached image, you will see "pressure tank" which has water on the bottom and air on the top. Sometimes, the water level gets too high, so there is insufficient air to push the water through the system before the pump comes back on, causing short cycling, and this technical note addresses this particular problem. I used to live in a house with well water, and this is the kind of system we had. We occasionally had to bleed the pressure tank of the water so air could get in, otherwise, the pump would come on too frequently.

The problem is that i expect that all lever machines are slightly different when it comes to the pressure needed on the lever...and i don't have the equipment to do any measurements myself.
However, i believe this is correct, in a static condition where the machine is completely choked:

F = (p * pi * r² * La)/Lb

"p" is the brew pressure in bars (900,000)
"pi" is pi (3.14...)
"r" is the inner radius of the cylinder in meters
"La" is the distance between the two screws on the lever (from the screw that attaches the lever to the group to the screw that attaches the lever to the piston)
"Lb" is the distance from the screw that attaches the lever to the group to the point at the handle where you apply your pressure.
"F" is the force that you use to pull the lever, in newtons. Multiply that with 0.22 to get whacky non-standard units (pounds;))

i think 200lbs of pressure is suposed to be applied for it to go verticly
