Product Overview

Use the Basement Watchdog Battery-Operated Water Alarm to detect leaks before costly water damage occurs. 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.

Customer Questions & Answers

if the alarm goes off and you repair the leak, will the alarm reset when dry so that it can be use again or is it just for one use ??

Asked by: Geo
yes. The alarm is really just a switch that turns on the speaker. If water completes the electrical circuit, the batteries will send power to the alarm speaker. You can test it whenever you want by touching the two contacts with your fingers.

Will high humidity trigger the alarm?

Asked by: Me
Only if it makes a connection between the contacts. Of course over time, it is possible that components inside the unit will degrade from corrosion. But, like your smoke alarms, which I know you check once or twice a year, they are easy to test. A wet wash cloth or sponge held on the contacts for just an instant will trigger the alarm and removing the cloth, wiping the contacts will turn it off, and you're good to go.

How Long Will the Battery Last during an Alarm Condition?

With a fresh battery, and sensor in water, how long will alarm sound before the battery becomes ineffective? Does the alarm sound continuously or beep? If Beep, how long are the ON/OFF periods?
Asked by: Sexton
Not that I know of. So why not change its battery once a year like we do with smoke alarms??

How do you test it to make sure it works

Asked by: Richard
Just touch the two contacts with your fingers. You could use wire or just stick it on a puddle of water.

Battery-Operated Water Alarm is rated 4.6 out of 5 by 206.
Rated 4 out of 5 by from Excellent with one caveat You can't go wrong for the price. This little box does one thing and it does it very well. One warning, typical of products using 9v batteries: when the battery needs replacing, the connector can be very tight resulting in a broken connector when removing it to replace the battery. This renders the whole unit useless (not worth replacing it for the price of a new unit). The guy at my local Home Depot suggested I place some silicone grease on the connector before attaching the 9v battery. Won't know for a few years if this is a solution, but it sounds like a good idea.

I had a few water leaks under the sink that this device caught immediately. I own about ten of these alarms now. I've had some of them for a few years. They are great. Set it on the surface and you're done. The sensor is easy to test. Just touch the two metal contact buttons on the bottom with your fingers. Watch your ears. It stops as soon as you discontinue the test. Small; a little bigger than a pack of smokes and a lot better for you. With the included wire, they are flexible enough to monitor remote locations. I even used one to detect a leak inside the ceiling by sticking bare wire to the back of the drywall (ceiling below an upstairs bath and toilet). I ran the wire through a tiny hole in the drywall and connected it to the alarm. If or when there's enough water to complete the electrical circuit between the two wires, the alarm will sound. I did this in a garage below a bathroom. Obviously, you wouldn't do it inside your house (well, maybe in a closet). I'm planning on monitoring my crawl space plumbing with one. Put them next to the washer, under sinks. Put one next to the bathtub if one of the kids has a habit of carelessly letting water get past the shower curtain. One alarm will cure them of that.

Also, have not tested if it works or not ... 100+ decibel alarm should be pretty loud! Would get 5 stars if it had test mode, battery charge meter and came with battery.

I bought two of these one for near my hot water tank and one for the upstairs bathroom. Very easy to set up, just install battery and set down. Hopefully I don't ever hear it.

Rated 5 out of 5 by from product gives peace of mind ref leaks The alarm offers an alert before major damage (unless it is a major pipe break). The design of the detachable sensor provides options on location of sensor and the alarm unit.
