1. A leak detection device for a liquid container comprising:
- a three layer sensor, having two detachable ring halves, dimensioned to encircle said liquid container, said sensor having a first layer, closest to said container, flexible and conductive, having a resistance ranging from 0 to 2 megohms, said sensor having a second layer, furthest from said container, flexible and conductive, having a resistance ranging from 0 to 2 megohms, and said sensor having a third layer, sandwiched between said first and second layers, said third layer nonconductive, wherein a leak in said container will cause the sensor to produce a signal corresponding to said leak by completing an electrical circuit through said first and second layers; and
wherein said sensor further comprises flexible and conductive strips with looped terminations, said looped terminations physically support said sensor and substantially conform to the contour of the surface said sensor rests on.

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.
