ABSTRACT:
A water storage and pumping system with a motor control for the pump, which is responsive to storage tank pressure and comprises an analog pressure tank and a low pressure responsive valve to admit water from the storage tank service line to the pressure tank and a high pressure responsive valve which allows the pressure tank to drain through a time delay bleed valve. A pressure responsive electrical switch senses the pressure tank pressure and controls operation of the pump.
