SABRE Water Leakage Alarm, 110 dB Alarm, Audible Up To 1,500-Feet (457-Meters), All Direction Water Sensor, High and Low Volume Settings, Battery Test Button

I didn't put in anything for battery life as I only have had it for 3 weeks. It was loud enough to wake the dead. LOL!

This has already saved my living room twice from a potential flood as I was dealing with a leaking aquarium filter that could have leaked 250L...

Does the job. Really loud

I have had issues with my HVAC moisture pump failing in the past, causing wet carpet. So I thought ahead this time and installed a spill tray with this alarm. I tested it and WOW this alarm is loud. The bonus is that my in-home cameras picked up the alarm going off as well so while this alarm is NOT wifi connected, my cameras let me know it was going off with sound notifications anyway! This is a great leak alarm!

I've tried a few water leak alarms and this one is by far the best bang for the buck. First off, it's so loud. It makes smoke detectors sound like they don't even care. The tethered probe is short but still very handy to have compared to the models with the prongs on the bottom of the housing.I've installed this a couple weeks ago and it's already saved me. My sump pump failed due to freezing and the pit was filling up. I have the alarm on the sump pit cover and the probe hanging into the pit. I was able to catch this and replace the pump before any water ended up on my floor.Also, this only uses 2 AAA batteries compared to the standard 9 volt which is nice.
