ABSTRACT:
A leak detection device for preventing damage from leaking hot water tanks. The invention features a unique three layered sensor that completely encircles the hot water tank thus detecting the occurrence of leaks any where around the tank. Circuitry controls the sensor that provides for accurate detection of even small amounts of moisture so that any potential leak problems can be remedied before a major spill occurs. The device is powered by connecting it to 110 house current. A 9 volt battery is provided for battery operation of the device and is also provided a back-up in case of power failures.
