<p>An adjustable hydraulically operated pressure management control pilot assembly has first and second diaphragm assemblies which define two fluid pressure chambers. Varying the pressure between these two fluid chambers modulates the control pilot assembly between adjusted low and high set points, which can be used to control high and low pressures downstream of a pressure reducing valve of a water supply system.
