ABSTRACT:
A system for monitoring leaks in dwellings that includes a sensor which detects water flow. The system determines that a leak is occurring when water has flowed through a water line for longer than a preselected period of time. A central monitoring system receives a signal from a local system and the central monitoring system has an associated record for each dwelling to thereby allow flexible response to correct the leak.
