1. A pumping and water distribution system for a pool or spa, comprising:
a pump including a variable speed motor;
a controller controlling the speed of the variable speed motor;
a plurality of pool/spa components;
a plumbing subsystem placing the plurality of pool/spa components in fluidic communication with the pump; and
a plurality of control valves switchable between an open position and a closed position,
wherein each of the plurality of control valves is associated with one of the plurality of pool/spa components, is positioned in the plumbing subsystem between the associated pool/spa component and the pump, and controls the flow of fluid to the associated pool/spa component,
wherein each of the plurality of control valves is adjustable and calibratable such that each of the plurality of control valves is capable of providing different flow rates based on a set system pressure when in the open position,
wherein the controller adjusts each of the plurality of control valves, and calibrates each of the plurality of control valves based on the set system pressure and a required flow rate of the associated pool/spa component such that each of the plurality of control valves provides a specific flow rate of fluid to the associated pool/spa component based on the set system pressure when in the open position, and
wherein the controller adjusts the speed of the variable speed motor thereby adjusting a pressure of fluid within the plumbing subsystem to the set system pressure.
