Pumping water with compressed air.

This is a short demonstration of pumping water using compressed air. I have the small pipe pumping air down and the larger pipe brings the water up. I wanted to film a bit longer but my little compressor died. The engine is an old kirby/tecumseh engine i got off a mower and is tired. I will get a bigger compressor and pump the bore for a couple of days to test it's production level so i know what size electric pump to install. It is taking about 85psi to bring the water up from about 250ft but i am not sure what the water level in the bore is, as it drops will be harder to pump. In this demonstration it was producing abour 400 gallons an hour. A very inefficient way to pump but most probably the easiest at this depth.
