Abstract: The present invention provides a smart flow anomaly detector for a liquid distribution system comprising a flow measuring device that derives a liquid flow value for both automatically operated fixtures and manually operated fixtures. A microprocessor is in communication with the flow measuring device and is programmed to use the liquid flow value and a threshold liquid flow value to determine whether a flow anomaly exists. If a flow anomaly exists, the automatically operated fixtures and/or manually operated fixtures may be shut off and there after liquid flow to the automatically operated fixtures will be controlled based on a comparison of the liquid flow value attributed to the automatically operated fixtures and the threshold liquid flow value. Additionally, in a preferred embodiment of the present invention the microprocessor will generate a warning to alert the user when a flow anomaly occurs in the liquid distribution system.
