WELL SYSTEM Abstract of the Disclosure A well system comprising a pump having an inlet and an outlet and a combined pressure regulating valve and pressure tank. The combined pressure regulating valve and pressure tank comprises a hollow container having a diaphragm therein overlying an inlet connected to the outlet of the pump and an outlet connected to the system. The diaphragm is urged by a charge of gas in the container to normally seal the inlet and outlet to said chamber in the absence of fluid pressure from the pump sufficient to move the diaphragm away from the inlet and outlet. Thus, the combined pressure regulator valve and pressure tank functions to insure that the flow from the outlet is substantially at a predetermined pressure and that when the pressure falls below a predetermined amount, the diaphragm seals against said inlet and the outlet to said chamber and maintains water in the outlet of the pump sufficient to maintain a prime on the pump and prevent the pump from running dry. - i -
