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.

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

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!!
