Essential Info

Get advance notice of potentially hazardous water leaks in your home or office with a system that alerts you when water buildup is detected. The Waterbug 800 8-Zone Water Sensor Alert Kit can monitor up to eight supervised or 16 non-supervised zones; four supervised sensors are included, additional WaterBug Surface Sensors (sold separately). The sensors detector work by forming a conductive bridge between two electrical contacts when it senses the presence of non-flammable conductive liquids. When water or moisture has been detected the main unit will alarm or trigger a relay on virtually any alert/security system such as EnviroAlert or automation system that accepts a dry contact closure. This water sensor kit is ideal for bathrooms, laundry rooms, basement sump pumps, drain areas, computer rooms, document storage areas, warehouses and sprinkler systems.

Please Note: The Waterbug does not work with de-ionized water.

    Works great, however I have not been able to make a non-supervised water sensor work. But the supplied supervised sensors work nicely.
