The Basement Watchdog 110 dB Battery-Operated Water Alarm

Simple, inexpensive, and works. Saved our finished basement, or at least a lot of headache. Detected a water heater leak, with a loud enough buzzer that we heard it across the house and investigated. Caught it at a small leak before spreading, shut off the water to the heater, and got it replaced. Otherwise it would likely have been weeks or longer until we discovered the leak.

In March of 2024, I purchased the “Basement Watchdog Model BWD-HWA 110 dB Battery Operated Water Alarm” from Amazon and good thing I did. I positioned the small sensors in the tray below my hot water heater in my laundry room. About two weeks ago, my hot water heater broke and the Basement Watchdog did its job! It set an alarm off. Yes, the alarm was loud but it was effective in alerting me to a leak that was taking place. The water alarm was reliable and easy to install, taking seconds to set up. It was effective in preventing water damage and it saved me thousands of dollars in potential damage! It really worked!!

THE BASEMENT WATCHDOG Model BWD-HWA 110 dB Battery Operated Water Alarm, has been an excellent addition to my home safety setup. This water alarm is perfect for placing next to water heaters, next to the dishwasher or laundry room, under kitchen and bathroom sinks, and by AC drain pans. It saved me big from a leaking water heater! The alarm is powered by a 9v battery, which makes it very convenient to install anywhere without worrying about electrical outlets. The 110 dB alarm is loud and ensures that you can hear it from anywhere in the house, giving you peace of mind that you will be alerted to any leaks or water issues promptly. One of the standout features of this product is its extended cable, which allows you to place the sensor separately from the main device. This is incredibly useful for those hard-to-reach spots where leaks are most likely to occur but where placing the entire device might be impractical. Make sure to test it periodically by touching the two sensors with a finger. I also write the date of installation on the battery and change it once a year. With the cost of insurance and labor going up, don't skip on this economical and reliable home protection device! Overall, THE BASEMENT WATCHDOG Model BWD-HWA is a reliable and effective water alarm. It's easy to set up, provides a loud and clear alert, and offers the flexibility to position the sensor in the most critical locations. I highly recommend it for anyone looking to protect their home from potential water damage.

Purchased because my neighbors have two. Both our basements flooded last weekend and they had the alarm we didn’t. When a storm knocked out our power the sump pump was turned off. They heard the alarm and were able to start bailing water out. I had two inches of water in my basement. 4 stars as it could be louder. I will here it on the first floor but definitely not on the second.

These things are great & loud enough to hear even from the basement. I put these all over the basement & in my furnace hot water closet. This thing gives you enough time to get to the problem & shut the source off before to much damage happens. They are so sensitive that it picks up the moisture in your fingers when to touch the contacts & the sensor detaches with a long wire so you can leave the sensor downstairs & mount the alarm in a closet upstairs for even more protection. Runs on a 9v battery & i change them out once a year. Cheap protection for the price

As a plumber I like to give these to my customers and have tried a lot of water alarms. Been using the watchdog for 8+ years and love the functionality and durability of these alarms. If you’re wondering which one to get, this is the one

Great gadget, reasonably priced, it can easily pay for itself and save you from water damage due to a water heater leak, very low maintenance, loud enough to be heard.

My home was built in 2000. Unfortunately, the builder used the cheapest plumbing materials they could get. As a result, I experienced an extensive water damage event in 2003. After my home was repaired, I wanted to do something to help protect myself from future issues. So, I got several of these Watchdog Water Alarms and placed them in key locations like the bathrooms, the laundry room, and the kitchen. I've added additional alarms over the years to cover every potential leak spot I could think of. I now have 14 of these alarms in my home. Well... This week, they paid for themselves! I was in my home office, on a conference call, and I heard an unfamiliar noise. I ignored it for a couple of minutes but eventually excused myself from the call so that I could investigate the noise. Within another few minutes, I had tracked it down to the kitchen, then to the cabinet under the sink. When I opened the cabinet doors, the problem was clearly evident. The supply shut off valve to the faucet was spraying a small stream of water. The bottom of the cabinet was wet, but nothing that I couldn't mop up with a few towels. The only casualty was a box of dishwasher detergent. Other than that, there was no harm done thanks to the alarm. Without the alarm, there's no telling how long the leak would have gone or how much damage would have been done. Now that is great, but something else about these alarms amazed me. Having the alarm trigger reminded me that I couldn't remember the last time I had changed the battery. So I picked up every alarm and checked them. The battery in the alarm that triggered had a shelf date of 2011 -- That's 14 years ago! And that means that I hadn't changed the battery since at least 2011. --Shame on me. But the alarm still did its job! As I changed the batteries in all of the alarms, I tested them by placing them on a damp paper towel. Every one of them sounded the alarm. Even the one with a battery dated 2008 (17 years ago). --Double shame on me. ;-) --I've learned my lesson and set myself a reminder task to change those batteries in a few years. So bottom line, would I recommend the Watchdog Water Alarm to a friend? ABSOLUTELY! And without hesitation!

I tested the watchdog several times, worked perfect !.. hope I never hear that alarm again ... lol ... I will buy again

No es estético pero cumple su función. Ojalá que hagan versiones más estéticas.

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.

Easy to install,very loud alarm. Simple,simple simple. Only has to function one time to save major home damage.
