Abstract
PURPOSE: Provision of an automatic well pump having a pressure reducing valve connected between the pump and a pressure tank, said pressure reducing valve providing therein a small hole through which the upperstream and downstream sides are permanently in communication with each other so that the deliverly pressure be kept constant while the pump is adapted to stop its operation when the pumping delivery of water is reduced to zero.
