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.

What does the alarm sound like?

Is the alarm sound similar to a fire or CO2 alarm? I'd hate to evacuate my family in our pajamas in the middle of the night because a leaky sink pipe triggered this alarm, if it sounds too much like a smoke alarm.
Asked by: Bob
About the same sound, pitch and volume as a smoke alarm.

is the sensor submersible? For use in a sump crock where the water could rise above the sensor before you fix the problem.
Asked by: mike
The leads are submersible and there is about 6' of wire between the leads and the alarm unit. The alarm unit is not submersible.

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.

Having just experienced a unwelcome hot water tank replacement experience my immediate concern was to focus immediately on getting my new 50-gallon 7-year Rheem hot water tank installed as quickly as possible then follow up with finally purchasing a few of these water alarms to minimize water damage should my washing machine hoses and hot water tank decide to "take a dump". Researched all the available battery operated water alarms and this particular got quite a number of high reviews on both ease of use and reliability so off to Home Depot I went (again!). Price per unit at Home Depot is either quite competitive or even cheaper than eBay. Purchased two initially to put to use .... washing machine area and the gas fired hot water tank. Easy to move about but even easier to attach to where you want this to do it's work....I used either double sided sticky tape or velcro to adhere the sensor part to the lowest part of the floor and trial test by allowing a few drops of water to dribble past the sensor.....Wow!, this alarm works as intended and is loud enough such that I can hear it in the bedroom 2 stories above where these sensors as attached. Will pick up two more of these units to place under sinks just to insure our recently renovated basement bathroom is not ruined by water damage.

Rated 5 out of 5 by from What's that noise I had hot water heater issues. On impulse, I purchased this sensor with the needed plumbing supplies. 4 days later I get a call from my wife, "there's an alarm going off in the house but I can't find it". Another leak had developed. The puddle was smaller than a dinner plate. Had the leak gone undetected, it would have caused major damage. This $12 sensor likely saved us $100's. I went back and bought 5 more for other places. Cheapest insurance I've ever purchased! I highly recommend this product.

Haven't had a leak since I purchased this so I can't provide actual product-performance feedback. However, in the tests I did before placing the device (next to water heater, behind washer, under 2 sinks) it performed well. I put water on the counter top and set the device in it. Alarm went off immediately (sounds like a smoke alarm). Also tested with a slightly damp rag. Same result. I don't have any experience with other water alarms but this seems like it should do the job.

It detected a leak from the washer soon after the wash started. Without it, the leak would've gone unnoticed and become a much bigger problem. I have several units in my house. I did have to replace one after about 3 years because after I tested it, the alarm wouldn't stop, even after replacing the battery.

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.
