Battery-Powered Water Alarm - 110 dB Siren Alert by Basement Watchdog

JohnnyLee: Have this sitting on the floor under our hydroponic rig that holds 6 gallons of water. A water line from the hydro pump popped off and started pouring water onto the floor. Heard this alarm go off from the basement and was able to run downstairs and shut the pump off. Lost about a half gallon of water but this device saved me a major headache.

James: After repairing the floor twice because of a refrigerator leak I placed one of these behind the fridge. Works great, I placed a little tissue under the contacts because I thought they sat a little high. Had it behind the fridge last week, knocked a cup over and a piece of ice went behind the fridge. When it started to melt it set off the alarm. Scared me until I realized what it was. Felt good that it did work. Purchased another to go behind the washing machine. Just a little security.

HR: Works great. just place on floor and as soon as water contacts it - it alarms. To shut the alarm off just wipe the contacts dry and alarm stops! The alarm is loud enough to be heard one floor away. Note: does not come with a battery!

Clayton T. Tevebaugh: I have a door drain in my utility closet for the hvac drain. Somewhere in my line there was a clog and there was a prior water backup in there. It was a huge mess replacing the floor in the hallway next to it. After that I bought this product to notify me if that ever happened again. Today it saved my butt! I was sitting at my computer and heard the loud beep then I was like oh noo! Turned off the washer that was making the overflow and I was able to fix it before it got worse. Who knows how many loads I would have ran before catching the issue.

Brian D.: I've had Basement Watchdog water alarms by my furnace and water heater for years, but after a sink leak, and a toilet leak, and a AC drain line leak, I bought a bunch of these alarms and put them EVERY place I have plumbing or drain lines. I also put one by my sump pump, since sump pump failures are surprisingly common.

It doesn't draw any current until it detects water, so if you put in a good quality battery, it will silently guard your house for several years. It will work better if you set it on a paper towel, so that any water in the area will be quickly absorbed and will trigger the alarm.

The alarm is loud, but it is just a steady, very high-pitched tone, which can be hard to hear if you have any hearing loss. A warble or beeping tone would be better, but they have a newer model that has a siren that sounds like a smoke detector alarm.

I like that it comes with a built-in six foot cord hidden inside the body, so I can extend the sensor to a hard-to-reach place.

These alarms do a very good job, but there are newer wireless sensors that communicate with a central receiver; can alert you through phone or email even if you are not home; and can even...

RichardRichard: J'ai une pompe de puisard au sous-sol qui rejette l'eau à l'extérieur quand la nappe d'eau monte trop. J'ai installé le détecteur à 6 cm (2.5 pouces) sous le niveau du plancher en le vissant sur une petite planche (Voir la photo). À l'arrière de la boîte principale, il y a une encoche qui permet de l'accrochée au mur, maximum 1.5 m (5 pieds) plus haut.
Il arrive, surtout au printemps, que l'eau monte plus que normal et s'il manque d'électricité ou que la pompe tombe en panne, j'espère être avisé par le son "strident" de l'alarme. J'ai testé le détecteur et il fonctionne normalement.

Pat: I bought this because my dishwasher blew the drain hose and the water leaked through a downstairs light fixture. I built a galvanized catch tray and mounted it in under the dishwasher which is a built in and not real easy to see when a hose is leaking Then mounted the Glentronics sensor in the tray. I then drilled a hole in the side of sink cabinet and mounted the glentronics alarm in a out of the way spot. I now have easy access to the alarm to change the battery or stop the alarm. There is lot's of wire to do this. I now feel I will know about any future blown hose before any other damage occurs. Makes this well worth the very reasonable price of purchase.
