Water Leak Detector Sensor Alarm: Home Water Flooding Monitor Smart Sink Overflow Monitoring Adjustable Wet Moisture Alert Pipe Leakage Drip Detection Warning for Basement Floor (1 Sensor)

I’ve never been so happy for an impulse buy! Rain in the middle of winter, the ground not frozen yet, the sump pump filled and a joint had come in done, water spraying everywhere. Had it not been for this little water leak detector, it could have been -days before we went to that area of the house and the damage we would have found!! I think that the water was detected almost immediately! I heard the beeping and investigated!! Now, the alarm could have been louder as I heard it one floor above and it is not that alarming! The alarm was similar to a low battery in a smoke detector. Very easy to use, turn on and set on the floor next to the sump pump. Good gadget!

This water leak detector truly saved the day. It works exactly as expected and alarms us immediately when it detects water. The alert is loud and fast, which helps prevent bigger damage. A simple but extremely effective device to have at home.

I’ve had a 60-gallon reef tank for almost two decades, which means I regularly mix fresh saltwater very other week. I always set a timer to warn me when my salt mix bucket is about to overflow, but sometimes the water fills at an unpredictable rate, and I’ve ended up with mini floods in my kitchen more than once. So, I finally decided to get a water leak sensor. At first, I looked into smart sensors that connect with Apple Home or Samsung SmartThings, but they were pricey ($35+), had non-replaceable batteries, low audio alarm, and had frequent complaints about disconnecting from the system. Instead, I went with a simple, battery-powered water sensor, and I’m so glad I did! This device is not only loud but also incredibly accurate. The moment even a tiny part of its foot touches water, it sets off a piercing alarm (and I mean LOUD. I can hear it from several rooms away). Best of all, it’s a straightforward device with replaceable batteries, and I can even use rechargeables. No complaints whatsoever, and for this price, I can’t recommend it enough!

Cool product. Works two ways alarms on wet floor and also when dripped on.

Tested it and works great, soon as moisture touches the four metal legs on the bottom it sounds the alarm. Says it will also alert when the battery is dying which is perfect. I don't check my basement often so if a sump pump fails this will alert me before the issue becomes catastrophic.

Seems well made and works. I tested it in a dish of water. Alarm is very loud. This product will help prevent prolonged damage from a water leak. I bought 2 and put one by washer and the other by the hot water heater

Well I bought this years ago and set it under our water heater just in case of a leak. Fast forward to today, I awake to a terrible noise and lo and behold this thing worked! It alerted us to a leak hours before we would’ve naturally discovered it. It is loud and it did its job!

Works as stated!! I have in the basement can here it on the 2nd floor of my house.

Just arrived. I tested it, it does sound when water touches its sensors. Very loud alarm for my apartment, but not sure if it is loud enough if you place it in an American-style house basement. Edit: It has since consistently worked for my leak. Loud alarm every time, good product

It's just what I needed for my basement it works...what more can I say!

Fait très bien le travail mais n’est pas connecté au wifi ou à quoi que ce soit donc il faut être sur place pour entendre sonner. La sonnerie est très forte c’est un avantage

No floods yet. seems quite simple.

I held off on reviewing this as I hadn’t had a water leak yet. Our washer has leaked twice in the past year which was what prompted me to purchase this alarm. Yesterday the alarm sounded when I had a load of laundry in, and sure enough it was leaking water. I was very happy to be able to address the problem quickly without my basement flooding or the water causing any damage.
