Abstract

The preferred embodiment of the water leak detector of the present invention comprises a detection device and at least one water sensor. The water sensor includes a pair of elastic conductive metal tapes affixed to at least one tape-like water absorber made of a thin water absorbing material, a socket to which the pair of conductive tapes is plugged into, and a sliding shoe to which the tip of the metal tapes are plugged into. The water absorber is dipped into a salt water pond in the production process so that it includes salt within and on its surface. The detection device includes a housing; a battery socket; an alarm; a toggle switch; a push button switch; and a pair of cables that connects the detection device with the water sensor.
