Essential Info

Get advance notice of potentially hazardous water leaks with a system that alerts you when leaking water is detected. The Water Bug Leak Detection System can be used with virtually any security/home automation system that accepts a dry contact closure as a signal. Use it with the EnviroAlert Systems, X10 Security System Wireless Transmitters, the JDS TimeCommander Plus or a Sensaphone.This battery-powered version has normally-open contacts only and requires a 9V battery (sold separately).

The WaterBug Leak Detection System comes with one surface sensor. This battery-powered version uses one 9V alkaline battery (not included) with approximately one year battery life.

    GARY -- louisville, CO   1/27/2013
    battery holder and low battery LED would be useful additions
    DAVID -- perrineville, NJ   12/23/2012
    Easy to install. Good instructions.
    THERESA A -- westlake, OH   4/3/2012
    It works fine, but it's completely unclear from the descriptions that it requires an extra component to actually hook it up to the ISY-99i. Still working on this one.
    JENNIFER -- farmington, CT   1/18/2010
    There are no step-by-step instructions so it's just sitting here and I have no clue what to do with it.
    SALVATORE -- peabody, MA   12/18/2009
    The sounds is not very loud if you are hoping to hear it from another level in the house. I thought it could wirelessly communicate with sensaphone, but I was wrong. Also, the directions were bad and it took three fairly educated adults to make sense of wiring scheme.
    JOHN -- fairbanks, AK   2/12/2009
    Works great
    ELAINE -- watertown, MA   11/6/2008
    The water-detecting switch does make the connection I needed, but I did not need the rest of it to work the dialer.
    FRANCOIS -- gatineau, QC   5/23/2007
    Works OK and as claimed but the built-in sounder should be louder and the battery compartement should be redesigned for easier access.
    CLARA -- bellingham, WA   11/17/2003
    Worked fine. Used this item with the 4 channel long range transmitter / receiver to monitor water level in basement sump pump basin in my elderly mothers basement. If water level rises to sensor,(set above pump normal operating range) I am alerted that there is a sump pump problem.
    WALLACE -- plainfield, IN   8/9/2003
    very satisfied overall
