  • Patent number: 6323774
    Abstract: A monitor, shutoff control, and alarm for use with an inlet water supply obtained from a municipal water supply to prevent excessive usage of water due to leakage or human error, that includes a measuring means and shutoff valve connected to the inlet supply, a processor that includes a program for setting threshold values of water volume per unit time anticipated by the particular household, which, when exceeded, will set off an audio alarm or will activate a telephone dialer to call a predetermined number if no one is at home. The system is programmed in volume increments of time, such as hours, days, or weeks, to accommodate systems that include sprinklers which may require some volume of water over a short period of time.
