I use screw in pressure transducers quite regularly (0 - 1 Bar or 10 metres) To check the calibration I usually carry a 5 metre section of clear hose, a funnel, food colouring, tape measure and a valve and tap arrangrement. This involves climbing the nearest stucture or tree and hnging the pipe so I can fill it with coloured water. Very accurate but a pain.
I dont think a pump up system and a gauge will give the accuracy I require.
This now is a physics questions, is there a way to get say 5 metres of water pressure if you have a system only 1 metre high. ( like a pulley arrangement where the number of ropes is the mechanical advantage)

PS Or another accurate way to test in the field
