Can anyone point me to plans for making an air powered water pump? I want to use it to fill a stock tank and water some trees without using the submersible. It will use a windmill turning a compressor, I can manage to rig that up. Air will be compressed in a tank, and that will go down the well to the pump that I can't figure out. If the wind quits blowing and I need water, I can charge the tank with the shop compressor.
