ABSTRACT:
Water pumping apparatus is described for use with wells in which on-off cycling in pump operation is minimized by providing an air compressor and compressed air holding tank feeding an pressure regulating valve connected to discharge into a water holding tank, thereby enabling constant pneumatic pressure to be maintained in the water tank without regard to water level in the tank so that each cycling of the water pump will completely fill the water tank from nominally empty condition to nominally full condition.
