Essential Info

Get advance notice of potentially hazardous water leaks with a system that alerts you when leaking water is detected. The WaterBug Leak Detection System can be used with virtually any security/home automation system that accepts a dry contact closure. Use it with the EnviroAlert Systems, X10 Security System Wireless Transmitters, the JDS TimeCommander Plus or a Sensaphone. This AC-powered system has normally-open or normally-closed contacts and requires a power supply, sold separately.

The WaterBug Leak Detection System comes with one surface sensor. You can also add up to 5 additional sensors (sold separately).

Also available in a battery-powered version.

Note: The Waterbug does not work with deionized water.

    The ad plainly advises that an external power supply is needed. Download the installation manual if you are unsure of buying or not. This device works exactly as advertised by Winland. We use these in conjunction with our Security System installations where desired by clients. Heavy condensation will put them into an alarm state. When using them in enclosed sump holes you should suspend the sensor by whatever means in the air in the sump hole and this will save false alarms due to condensation.

    Works really well. Feels like it is built really well., Purchased a 12VD.C. transformer and siren from Radio Shack. Very basic and simple assembly.
    DON -- owings, MD   7/8/2013
    Works well.
    SHERRY -- roscoe, IL   5/13/2013
    Product was received in a timely manner. Work great. We ordered more.
    HEE LAI -- kuala lumpur, Malaysia   5/2/2013
    Arrived safely and in advance. Great service.
    JONATHAN -- blairsville, PA   11/29/2012
    I bought these to tie into my flologic system.They signal it to turn off the water in the event of a leak.They work as intended.
    Waterphobic -- long island, NY   8/16/2012
    I'm thinking that the WB-800 which comes with four sensors and indicates by led which sensor is activated is a better solution for most.
    -- thornhill, ON   4/5/2012
    the perfect safety device for my application which is a 2nd floor laundry room. this unit is installed and connected to an electric water valve circuit providing automatic shut down and alarm in the event of leakage or burst pipe, saving my home from major water damage
    KEVIN -- ranburne, AL   12/25/2011
    Easy to install, and can be powered from multiple sources. MADE IN USA!
    JOSEPH -- garner, NC   10/30/2011
    Works fine, but says "may connect up to 6 sensors". I assumed this meant that they were set up as zones, but instead are just in parallel so you don't know which sensor is alarming. Also didn't come with the required power supply.
    AMIE -- paris, MO   8/29/2011
    We started off to be pleased with your device assuming it would protect against water damage. We tested it twice before permanantly installing the water bug and have now discovered that the sensor has failed.
    MERVYN -- farmville, VA   6/27/2011
    Does exactly what it says.
    PETER -- montana city, MT   11/14/2009
    Once I got the wiring right, it worked fine.
    Pete -- Montana   10/29/2009
    Had to purchase a power supply after I received the sensor and found I needed one. And then, it didn't work anyway. Hopefully, I'm doing something wrong, but I'll probably return it if I can't figure it out.
    LEE -- raleigh, NC   7/27/2009
    Exactly what it says it is. If used with a APC environmental management card there is no need for a seperate power supply, you can power it from the APC card itself.
    jerry -- Massachusetts   12/27/2008
    69*Waterbug water sensor does not come with a power source, and there is no apparent way to order it online at this site. Also, if power goes off, this device will send an alarm to the smartphone right away and there is no way to delay the alarm on the smartphone using the channel this accessory is attached to. A better choice may be the battery operated version of waterbug sensor. Wiring from Waterbug to alarm console is not included, either, so set aside plenty of time to ask questions instructions are cryptic and for trips to the hardware/electrical store for supplies to get this device up and running.
    SHERRI -- rochester, NH   10/18/2008
    This product could save hours of sleepless nights when I'm away from my vacation home.
    JOHN FARLEY -- pelham, NH   9/6/2008
    Good quality product. The instructions are sparse but cover the basics. No warning about needing an additional power supply, but this is overcome easily enough at the local HW store, so it's not critical. I bought 3 additional sensors so that the WaterBug will drive one valve on the water main and trip an alarm on the home automation controller, in case of a leak. Good product overall and will simply and easily protect the various areas that need it.
    LEE -- belvidere, IL   7/15/2008
    There was no indication that this unit came without necessary power. Now I have to track down a compatible power supply and wire to be able to install. Very disappointing.
    RALPH -- charlevoix, MI   11/26/2007
    States in description that a external power supply is required but does not give the specifications for the power unit.
