1. A method for controlling the selective loading and unloading of a plurality of fluid pumps connected for fluid input to a fluid distribution system to maintain system pressure of a desired level, said method including the steps of:

  • (a) determining the total volume of the fluid distribution system;

    (b) determining the rate of fluid leakage from the fluid distribution system;

    (c) determining the effect of the output capacity of each fluid pump on the fluid distribution system;

    (d) measuring any variation in demand on the fluid distribution system;

    (e) employing said total volume and/or said rate of fluid leakage to ascertain the amount of change in fluid input to the fluid distribution system required to match said variation in demand;

    (f) selecting one or more fluid pumps having a combined output capacity at least equal to said amount of change in fluid input to the distribution system required to match said variation in demand; and

    (g) loading or unloading said one or more fluid pumps to provide said change in fluid input to the distributution system.
