Testing the Brumby Pump How to pump out water using air

This water pump operates by using air pressure. It s amazing but it does work. I took a chance though but after seeing some clips on how it works I thought it worth a try. Fantastic method of pumping water. Next phase is to take it down the borehole about 500m from the water tank at the house. This will be the THE test but I m confident it will work. The water table at the borehole is quite close to the surface, about 3m. So that should be no problem for a Brumby.
