I'd placed one of the units near our troublesome west wall where it'd most likely to have issues. I was upstairs watching television when i heard it going off. I sprinted downstairs where i found water had just barely reached the unit. My older detectors would keep going off until the contact points were dry. These detectors stop sounding as soon as you pick them up as the design is different. A little thing but i prefer that aspect as opposed to the other type with metal prongs. I also was impressed by the tone and volume of these detectors. If i can hear it on the top floor while listening to a television then you won't miss the alarm wherever you are, assumingyou have a 'normal' sized home. These have the best design compared to the other units i tried out last year. All said for the money i couldn't be happier. , due to snow melting off the mountains that surround us, our sump pump runs nonstop from may through august every year. occasionally for a host of reasons the basement still gets water intrusion. when that happens I have to act quickly or a minor issue becomes a major job. that's why we rely on water 'detectors.' the ones we used the last two years were okay at first but then starting going off randomly and for no apparent reason. made worse as those were difficult to snap/pry open to stop them going off. I was very surprised and happy to find these detectors aren't a pain to open and shut. thankfully they made these with a screw on/off top! that one unique difference was much appreciated at my end. inside each was a nine volt battery. the only negative, and a minor one at that, was snapping the battery onto the connectors. it takes more force to do so than expected but that's it. on the bottom are two small protruding pin shaped bits of metal. water conducts electricity. so when you've got water on the floor, water allows current between those two and the alarm goes off. you can easily test it by touching both pins with your fingers. the alarm should then go off and you know with certainty you're good to go. FYI no worries in regards to testing like this. you cannot feel anything whatsoever when testing this way. I just find it to be a quick and effective is all. after the battery is in place and the two halves are screwed back together it's ready for use. place it wherever you want to be forewarned about water intrusion and that's it. I like these better than any we've used over the years simply because of the screw on design. granted it's early in the season but they've already gone off once. that's expected since i turn the sump off over winter and use these to know when it's time to power it up again. so, so far so good! Review: Water alarms battery operated. - These saved my basement from flooding a second time! No alarm first time. Alarm is not very loud 1 floor up (they are in my basement). It was faint beeping. Sump pump got clogged after first flood and these alarms both started beeping. Comes with 9volt battery kinda hard to connect. Really works great. I will be buying more. If I'd had these before would have saved my heating system and not shut off hot water heater. Arrived 2 in a box. ## Features - LOUD 100DB WATER LEAK DETECTORS FOR HOME- Each water sensor alarm leak detector features ultra-loud 100dB alarm audio which is loud enough to be heard throughout the house even if the leak happens in the basement, garages, or wine cellar.

No alarm first time. Alarm is not very loud 1 floor up (they are in my basement). It was faint beeping. Sump pump got clogged after first flood and these alarms both started beeping.

Arrived 2 in a box. ### ⭐⭐⭐⭐ Leak detectors work, but alarm is severely muffled if top half is misaligned *by S***F on February 27, 2025* I have no issues with the leak detection itself, but the design of these detectors is not good. Each consist of two halves, where the top cover screws into the bottom body. However, with the battery installed, the hole for the alarm speaker on the top cover (round hole) when fully screwed in, does not line up with the actual alarm speaker on the bottom body - the opening is ~180 degrees off! The result if there is a leak is the an extremely muffled alarm. If aligned the alarm is very loud, otherwise it will not be heard if located on another floor. So the top cover have to be unscrewed so they line up. But when the top cover and body are not fully screwed in, I'm sure the unit is not water tight. Update 3-3-25: The installation of the 9v battery affects the cover hole alignment to the speaker alarm. Added one star as the two halves can be screwed together with the speaker/alarm aligned by rotating battery and connector 180deg. ## Frequently Bought Together - Geevon 4 Pack Water Leak Detectors, 100dB Water Sensor Alarms Flood Detector for Basements, Bathrooms, Laundry Rooms, Kitchens, Garages, and Attics, Water Alarms Battery-Operated (Battery Included) - Amazon Basics 8-Pack 9V Alkaline Batteries, 5-Year Shelf Life - for Smoke/CO Detector, Electronics & Audio - THE BASEMENT WATCHDOG Model BWD-HWA 110 dB Battery Operated Water Alarm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/450450733-4-pack-water-leak-detectors-100db-sensor-alarms-for-home](https://www.desertcart.us/products/450450733-4-pack-water-leak-detectors-100db-sensor-alarms-for-home) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-31*
