Abstract
A system for early detection of water leaks at particular locations in any water-dependent appliance and apparatus used in multi-dwelling facilities. A central control apparatus electrically interconnected with a plurality of circuits that enable water leaks to be accurately detected in a diversity of devices including air conditioners, compressor coils, hot water appliances, and pipes, and for communicating the severity of the water-related problem. A plurality of water sensors are incorporated into specially designed probes of the preferred embodiment of the present invention wherein water leaks may be accurately and reliably detected in a diversity of water-dependent appliances and devices. A specially designed fiber glass cloth functions as a probe for sensing water leaks via its built-in plurality of sensors constructed from a corresponding plurality of conductive wires enables the location and extent of a water leak to be ascertained. The apparatus is designed to be easily installed and to be inherently devoid of any safety hazards. Specially color-coded wires enable particular appliances and pipes to be properly interconnected wherein water leaks may be detected early enough to prevent consequent water-damage. A detection transmitter contained with a central control housing uses information retrieved from a database to communicate the location and extent of water leaks to contact personnel disposed at a plurality of remote receivers. Transmission of voice and data alert and warning messages is effectuated via telephone lines and cellular communications.
