A method for monitoring a flow of a liquid in a distribution system within a structure, the method comprising: monitoring pressure at a first point in the distribution system, producing an output signal indicative of the pressure in the distribution system, wherein the distribution system further comprises two or more valves disposed at two or more different points of the distribution system; detecting liquid-related events occurring in the distribution system based upon one or more changes in the pressure indicated by the output signal; identifying a specific type of the liquid-related events that has been detected, from among two or more different types of events, by comparing characteristics of the output signal with one or more determinative criteria associated with the two or more different types of events; and automatically determining a volumetric flow rate in the distribution system as a function of the output signal and a predefined flow resistance for the distribution system, comprising: empirically measuring the volumetric flow rate at each of the two or more different points of the distribution system that are at varying distances from an inlet to the distribution system; and determining the predefined flow resistance for the distribution system at each of the two or more different points of the distribution system, based upon a change in pressure indicated by the output signal while the volumetric flow rate is being empirically measured. monitoring pressure at a first point in the distribution system, producing an output signal indicative of the pressure in the distribution system, wherein the distribution system further comprises two or more valves disposed at two or more different points of the distribution system; detecting liquid-related events occurring in the distribution system based upon one or more changes in the pressure indicated by the output signal; identifying a specific type of the liquid-related events that has been detected, from among two or more different types of events, by comparing characteristics of the output signal with one or more determinative criteria associated with the two or more different types of events; and automatically determining a volumetric flow rate in the distribution system as a function of the output signal and a predefined flow resistance for the distribution system, comprising: empirically measuring the volumetric flow rate at each of the two or more different points of the distribution system that are at varying distances from an inlet to the distribution system; and determining the predefined flow resistance for the distribution system at each of the two or more different points of the distribution system, based upon a change in pressure indicated by the output signal while the volumetric flow rate is being empirically measured. empirically measuring the volumetric flow rate at each of the two or more different points of the distribution system that are at varying distances from an inlet to the distribution system; and determining the predefined flow resistance for the distribution system at each of the two or more different points of the distribution system, based upon a change in pressure indicated by the output signal while the volumetric flow rate is being empirically measured.
