Claim 8:
9. A system for distribution of water to a structure comprising:
a logic-based electronic control module;
a primary electrically actuated valve having a normally closed state and connected, upstream, to a main water supply and, downstream, to a distribution system for the structure;
a sealed accumulator tank connected downstream to said first electrically actuated valve, said tank being partially filled with said water and comprising a flexible member separating a water-filled region from an air-filled region;
a pressure sensor connected to said tank,
said electronic control module being in communication with the pressure sensor and the primary electrically actuated valve;
the electronic control module programmed to:
determine, based on input from said pressure sensor, a flow rate of the water to the distribution system for the structure;
determine whether said flow rate of the water represents an acceptable water demand condition; and,
cause the primary electrically actuated valve to open if said determination of an acceptable water demand condition is positive,

wherein the system further comprises:
an inlet conduit, downstream the primary electrically actuated valve, for diverting water from the main water supply through an orifice; and,
an auxiliary electrically actuated valve for selectively causing water to flow through the inlet conduit from the main water supply to the orifice;

wherein the auxiliary electrically actuated valve is operable by the electronic control module which is programmed to open said auxiliary electrically actuated valve and measure the time it takes a system pressure of the main water supply to decrease from a first predetermined pressure to a second predetermined pressure based on input from the pressure sensor.
