Abstract: Systems and methods are provided for detecting and preventing fluid leaks. A rate of flow of a portion of fluid flowing through a fluid distribution network over a period of time is monitored. A determination is made whether the rate of flow of the fluid over the period of time is greater than zero but so low that it indicates a leak in the water pipe. If the rate of flow over the period of time indicates a leak, then the flow of the liquid through the system is stopped and an indication is provided that a leak has been detected.
