Flood Buzz Small Model | 3-Pack | Reusable, Easy-to-Use Water Leak Alarms for Homes and Businesses w/ Pre-Installed Battery

Wasn't sure if these littler buggers (see photo for scale) would do the job over the larger, more expensive and fancy competitors, but as soon as I installed one of them in the bathroom, it started to go off. Turns out there was a very slow leak coming from my toilet where the water line connects to the bottom of the tank. At first when the alarm sounded, which wasn't too jarring but loud enough, I thought it was malfunctioning because I couldn't see any water on the white floor tiles. I was able to make the necessary repairs and it probably saved me before the leak got worse and caused more damage.By the way, installation was a breeze. You just unwrap from the packaging and do the recommended testing of placing it on a damp towel to see if it is working. Then just place them near your sinks, toilets or any water source and hopefully you'll never have to hear the alarm. There is an expiration date which for mine was a little over 3 years. They don't have wi-fi to alert you on your phone, but maybe that's more for those who are away from their property for a long period of time.

These haven't alerted me to any floods yet, but when the circuit is completed with water, the noise is very loud and annoying so I'm confident it will work well. It's small enough to fit under the dishwasher which is what I was looking for.

These things definitely tell ya if you have water. They work very simply by the 2 metal prongs on the bottom of them, if there is water touching those prongs, they beep and they don't stop until you physically pick them up and remove them from the water (or I guess if the battery runs out, but we haven't had that problem yet.) On 5 occasions now, these things have told us immediately that there was water and saved us from having a massive cleanup. It doesn't take much water at all either, we put them directly on the concrete floor in the utility closet and the moment there was any water, they started sounding, so you don't need to wait until there is a catastrophe amount of water (even a quarter inch of water is a lot, so I like that these basically go off with even the smallest trickle of water.) They are not very loud though, that is my only complaint. We have these in the basement, and if we are upstairs in our bedroom (just one floor above) with our door closed, we cannot hear it going off. We can hear it slightly with the door open though, so I wish that they were just slightly louder. Also, these are very basic, you cannot sync them to an app on your phone or anything, so if there is water when you aren't home, these won't tell you that. Overall, for the cost, these were DEFINITELY worth it!

I’ve used these before and they work perfectly. I was recently alerted to water in the basement coming in through the bulkhead. The expiration date is right on the device and they are really inexpensive. I highly recommend this product.

These things really work. I put one under every sink and under my hot water heater. Not long ago one went off and sure enough there was a leak under my sink. Saved a major mess.

This is my second time ordering Flood Buzz leak alarms for my home. The alarms are sturdily made and compact, the alarm is loud, there were no "duds" in the two 6-packs I ordered, and they are plainly labeled with a battery expiration date/ replacement date 3 years in the future. My previous 12 Flood Buzz alarms lasted almost a year past their stated expiration date in 2024 (not that I'm advocating pushing your luck like I did, but I tested them regularly). One of the alarms recently alerted me to a leak under my water heater, averting a big mess, and making these well worth the cost. These are not the type of leak alarms that are smart-home-connected, so if you aren't in the house to hear the piercing alarm, they won't work for you. But I am home most of the time, and so they work for me. These are far better than the previous brand I used prior to 2021, which used up 9v batteries rather quickly.

Very easy to use. Take it out of the box and set it down. It just detected a leak today, and it was less of a mess because of this alarm. It was loud enough to hear on that level of the house, but not loud enough to hear from upstairs, so keep that in mind. That aside, It did exactly what it was supposed to do, and I’m happy with my purchase.

Works great!!! I forgot we had them until we had a small spill underneath the sink. The sound alerted us early decreasing the chance of permanent damage! Excellent product; put one everywhere in your house that could experience water damage!
