Zircon Leak Alert Water Leak Detector & Flood Sensor Alarm/Water Leak Sensor with Dual Leak Alarms 90Db Audio/Battery Powered (2 Pack) Batteries Not Included (72311) White

Great product, really loud, very sensitive. I have them inmy RV and all running wzter locations inthe house.

After a catastrophic flood turned half our home into a water park (thanks, broken toilet! ), we figured it was time to stop tempting fate and got a few of these units. And wow, are we glad we did! They’ve already saved us from what seems to be our ongoing battle against water. It detected a leak under the kitchen sink (seal gone bad), a dehumidifier that decided to hydrate the floor instead of the air, and an HVAC sump pump in the attic that apparently decided to take a break. I’m starting to think we’re just cursed when it comes to water. Should I invest in a boat next?I’m genuinely impressed by how long the battery lasts. Plus, the alarm is so loud that it could probably wake the neighbors...

I have to pull the battery and put it back in to complete setting up the WiFi. After I did that to both, it was easy to configure them

These are useful and pretty reliable. Have one under every sink, toilet, dishwasher, fridge, clothes washer, water heater, HVAC, etc., in my house where water is used. Cheap insurance against water leaks and has given me early alerts of several leaks over the years. They have probably saved me quite a bit in repairs from slow leaks can often otherwise go undetected until damage is done. One star off for price.....should only be about 10 bucks each at most and price has gone up too sharply over the past few years.

These really work! A must have for RV’ers. They have paid for themselves a couple of times when we had small leaks. It doesn’t take much water to set them off. I’m thinking of ordering some for our house to put under sinks and water heaters. Highly recommend!

I've had these water sensors now for more than a year. They alerted me to one leak, which prevented a messy situation.Instead of just beeping or chirping when they are triggered, they repeatedly send an SOS in Morse Code. This is helpful because it distinguishes their sound from other devices in my home that beep.Put one anywhere that a leak might occur and you'll save yourself a lot of money and anguish.

These work well. I have one in my kitchen and one in my bathroom. The alarm is loud! Could be a headache saver if an unnoticed leak happens while you’re in the house.

Bought these as a precaution to use on our waterheater and A/C unit after hearing about a waterheater leaking through the ceiling incident from a coworker. Months later the device I had placed in the pan under the A/C unit activated and could be heard loud and clear from inside the house. The main drain had clogged and was discharging to the pan. I'd say they have paid for themselves many times over and would highly recommend.
