Ipumped water today to supply my little cottage in the country. I estimate that I pumped 600 litres up to the main tank. This video clip begins with the end of the pipe in a river, my small pump (the size of a small log for the fire), and my diesel battery (larger than a car battery). I then raise the camera to zoom in on the cottage, and swing across to the one-ton tank where the water is going. OBSERVATION: That is quite some way to pump the water, but the little pump sends water up there with more than 2 bars (about 30 psi) pressure.
