I have a Gardena Water computer, the instructions say it works with a

you get from a water butt, say mounted a foot above ground level and 1/3
full? It would be nice to use it while away, as I am now on a water
meter I can just see a problem occurring while away and water streaming
out!

Pressure at the outlet of the barrel is purely due to the height of
water above the outlet. You'd need a column of water about 33 feet high
to generate 1 bar of pressure.
