A method for monitoring a flow of a liquid in a distribution system within a structure, wherein a plurality of different valves are coupled to the distribution system and wherein one or more of the plurality of different valves is associated with a specific fixture from among a plurality of fixtures that are coupled to the distribution system, the method comprising: monitoring liquid pressure at a first point in the distribution system, producing an output signal indicative of the pressure in the distribution system; detecting liquid-related events occurring in the distribution system based upon one or more changes in pressure indicated by the output signal; and identifying a specific type of the liquid-related events that has been detected, from among a plurality of different types of events, by comparing characteristics of the output signal with one or more determinative criteria associated with the plurality of different types of events wherein the step of identifying comprises: segmenting the output signal to isolate one or more discrete events of the liquid-related events in a sliding window of the output signal, based on pressure changes in the distribution system; classifying each discrete event of the one or more discrete events as either a valve open event or a valve close event, wherein the valve open event corresponds to a valve opening more, and the valve close event corresponds to a valve closing more; and associating the valve open event or the valve close event of the each discrete event of the one or more discrete events to a specific fixture from among a plurality of fixtures in the distribution system that generated the valve open event or the valve close event, using a template-based classifier. monitoring liquid pressure at a first point in the distribution system, producing an output signal indicative of the pressure in the distribution system; detecting liquid-related events occurring in the distribution system based upon one or more changes in pressure indicated by the output signal; and identifying a specific type of the liquid-related events that has been detected, from among a plurality of different types of events, by comparing characteristics of the output signal with one or more determinative criteria associated with the plurality of different types of events wherein the step of identifying comprises: segmenting the output signal to isolate one or more discrete events of the liquid-related events in a sliding window of the output signal, based on pressure changes in the distribution system; classifying each discrete event of the one or more discrete events as either a valve open event or a valve close event, wherein the valve open event corresponds to a valve opening more, and the valve close event corresponds to a valve closing more; and associating the valve open event or the valve close event of the each discrete event of the one or more discrete events to a specific fixture from among a plurality of fixtures in the distribution system that generated the valve open event or the valve close event, using a template-based classifier. segmenting the output signal to isolate one or more discrete events of the liquid-related events in a sliding window of the output signal, based on pressure changes in the distribution system; classifying each discrete event of the one or more discrete events as either a valve open event or a valve close event, wherein the valve open event corresponds to a valve opening more, and the valve close event corresponds to a valve closing more; and associating the valve open event or the valve close event of the each discrete event of the one or more discrete events to a specific fixture from among a plurality of fixtures in the distribution system that generated the valve open event or the valve close event, using a template-based classifier.
