This alarm can detect as little as 1/32 in. of water and produces a loud 110 dB alarm that can be heard throughout the house to provide an effective early warning system. The water alarm can be placed directly on floors or mounted for installation in a variety of locations: in a sump pit, near water heaters, refrigerators or dishwashers, next to washing machines, under sinks, close to air conditioner drain tubes or wherever there is a risk of water damage. The sensor with 6 ft. of wire offers installation versatility and can accommodate the addition of more than 100 ft. of wire. The water alarm operates using a single 9V alkaline battery and has a battery-saver feature that only uses energy when the alarm is sounding.

Can and how do you set the alert volume?

The alarm is GREAT! I was sleeping on the top floor of our house. The alarm was by the water tank on the first level. All you do is put a battery in it and unwind the cord. Put the little white piece at end of wires with the 2 sensors on the floor and/or under a cabinet. My husband has bad hearing, but I could hear something shrieking and ran down and stepped in 6 inches of water at 4 a.m. (My hearing is not so great either). Have used these for the last 10 years all over the home. Highly recommend!

i bought mine a few years ago and it is still working. It is supposed to detect water overflow on to the floor from plumbing leaks. the alarm is is always on only when the there is water touching the two leads built-in. To shut off just move it a dry spot.

One might be able to "rig" the alarm to act as a switch that would turn on your pump but it would take some parts and knowledge of electrical. I would certainly not trust it to activate a pump or any other device. It's just an alarm.

Is there any way that this alarm can also be connected to a sump-pump (that sits on the basement ...

It should. Alarm may be muffled inside wall and you’ll need to get at it to change batteries every 5 years

Just like chaining the batteries in your smoke alarms which I do on my birthday, I just do it every year. The batteries in theory will last 5 years but I am not willing to gamble on water damage to save a few bucks.

As a retired electrical engineer, I know that all the electrical components that make up modern electronics assemblies function at least down to 32 degrees Fahrenheit. I have two Watchdog water alarms lying flat on the basement concrete slab in unheated areas of my basement. Our basement air temperature dips to 40 degrees Fahrenheit in the coldest days of winter, but because I've never had the sensors get wet then I can't be sure that they would have sensed the water and set off the alarm. Buy the alarm and test it under those conditions. They did work for me when I tested them under other conditions.

I ordered this product on the recommendation of my water heater installer, set it in my drip pin (per manufacturer's instructions) and didn't think much more about it. This afternoon my husband and I were engaged in conversation when we were interrupted by an extremely loud, high pitched, almost deafening noise, shrill noise that was not only irritating but unrecognizable. After running around our house trying to identify the source of this offensive sound, we tracked it down to the little watchdog battery-operated alarm sitting in the drip pan of the new water heater we had installed about two weeks ago. Lo and behold there were droplets of water sitting in the drip pan possibly coming from the relief valve. We called the installation company who is sending their serviceman tomorrow to investigate and rectify. We would have never suspected or found the leak if not for this very inexpensive but effective alarm system. Would have had a flooded mess if not for this product. Have to say this was the best purchase I made in a long time and cost less than $20. Thank you BasementWatchdog" alarm system. Highly recommend!!!

Sat silent for years...then worked when we needed it most.
We bought this alarm at Home Depot 4 years ago when we moved into our house specifically to alert us in the event of something catastrophic occurring with our water heater or in case our air conditioning condensate pump failed. Both are in the basement right next to each other. So I stuck this unit on the floor right in between the two units and all but forgot about it for the next three years. I may have tested it once or twice in the first year. Anyway, fast-forward to this past winter... wife and I were sound asleep two floors up when an unusual noise woke me. I had no idea what it was (remember, it had been years), so I followed it down two flights of stairs, down a hallway in the basement, and into our utility room. There I found water coming from the underside of the water heater tank....not gushing, but definitely at an appreciable rate. I was able to cut off the intake valve to the water heater, turn off the unit, and drain the tank through a garden hose before going back to bed and leaving the rest to deal with in the morning. What a lifesaver! With an infant in the picture, my wife and I were no longer spending a whole lot of time in our basement. At that point I was venturing down there once a week MAX. This inexpensive little alarm sat in complete silence for years and then did it’s job when I needed it to, saving us from costly disaster. Don’t hesitate to purchase it...it’s well worth it!

Product fits in tight places. Tone on alarm sounds loud where you would notice it. Using it under fish tank in case there are water leaks from filter. Perfect solution to avoiding water damage.

The Watchdog Water Alarm is just what I've been looking for. I needed something that would detect the slightest amount of water on the basement floor without being overly sensitive to dampness. This product does just that. Unlike the product that it is replacing, the Watchdog Water Alarm doesn't falsely trigger in damp conditions - it requires actual water to be present. But it doesn't require much. Less than 1/2 teaspoon of water on a flat surface is enough to trigger the extremely loud, high-pitched alarm tone. Stopping the alarm is simple - just wipe the water from the two electrodes with a dry cloth or paper towel and the alarm stops instantly. Another great feature of the alarm is that the sensor plate, which normally is integrated into the alarm's housing, can easily disengage and be placed up to six feet away from the housing. That is especially handy for putting the alarm sensor into hard to reach places, like sump pits and the like. One feature that would put this product over the top would be to give it the capability to send alarm alerts via Bluetooth or WiFi, which would allow notifications outside of normal hearing range.

Works great. I use it in the laundry room which happen to be on the second floor. My cloth watcher malfunction and coused a flooding and caused some water damage. If I’ve had this alarm none of it would’ve happened as I would have been alerted and corrected the problem. I would highly recommend.

After my clothes washer leaked and almost ruined the floor, I bought three of these , washer, refrigerator water to ice maker, and most important hot water heater pan in the attic. Everyone should buy these to tell you when water is leaking. Great product.

TEN STARS! I have used this product for many years... everywhere there is a potential for a water leak, ESPECIALLY in places I can’t see, i.e. under the dishwasher and behind frig. A good battery (none included) lasts many years. I finally replaced them after 10 years “for the fun of it”.

Update to Previous Review. Worked perfectly! In my previous review, I had hoped the alarm would not go off. Just a few weeks later, it did! My A/C condensate drain had clogged and backed up into the overflow tray. With the alarm placed there, it detected the first drips of water and went off. Although it was not particularly loud, it got my attention. I was able to get the building maintenance people on the problem immediately. Worth every penny!

If water streams between the two sensors, it's no use. Overall however, it works well, the sound is very loud, and the box itself is small and nearly inconspicuous. This is my second device I've bought because I know the first one works so well.
