Review: ECONOMICAL AND EASY TO INSTALL - Thrilled with these basement water alarms! Easy to install and very economical, these alarms alert me when/if my sump pump pit malfunctions. This product gives me peace of mind. LOVE them!
Review: Excellent simple water leak alarm - I bought these because I have to filter my water for my saltwater aquarium. I use 5 gallon buckets and they fill so slow I would forget about them and i would have water everywhere. I just clipped one alarm on the inside of the bucket and it worked beautifully! The alarm is loud enough to get your attention, but not awfully loud. It alarmed 4 times and my floors are dry! It stopped alarming immediately when the sensor is taken out of the water. I am going to put 1 under my sink and 1 by the sump pump in the basement.

## Features

- Real-time Notifications (No Hub Needed): After connecting to Wi-Fi, you will be able to receive real-time email and app notifications remotely when dripping, leaking, or flooding is detected, without the need to purchase an additional hub. Share devices with family, and they can also check home status at any time. (2.4Ghz Wi-fi Only)
- High Sensitivity Drip Alarms: This device is equipped with four sensor probes at the top and bottom, which can detect a low water level of just 0.5mm. If water pipes drip, and your floor is submerged, or gets wet, it will sound an alarm. Water Leak Detector is compact and convenient in size, suitable for placement in laundry rooms, water heaters, dishwashers, sinks, and other places.
- Water Level Detection: Equipped with a 1-meter extended probe, you'll be able to detect changes in water levels of places like swimming pools, bathtubs, and fish tanks. It can also be placed in narrower areas, such as inside refrigerators or washing machines. And is suitable for homes, warehouses, basements, sinks, water heaters, pipelines, and more.
- Includes Loud Alarm Sounds: To help you stay alert, we've included 100dB high pitched alarms, which means even if there is a leak in basements or places a little further away, you'll know in a timely manner. Once discovered, you can manually set it back to mute without worrying about noise issues.
- IP67 Waterproof, Up to 2 Years Battery Life: Water Leak Detector is designed with a fully sealed waterproof shell and can easily handle high humidity working environments. It comes with 2 x AAA batteries and has a battery lifespan of up to 2 years. When battery is low, our app will also send notifications to remind you to replace them in a timely manner.
- Part of SwitchBot Ecosystem, Voice Command Compatible: Use with SwitchBot Plug Mini or Indoor Cam, and remotely turn off electrical equipment or check the condition of your house in case of leakage. It can also support third-party services such as Alexa/Google/Siri/IFTTT/SmartThings.

### ⭐⭐⭐⭐⭐ Excellent simple water leak alarm
*by W***D on March 24, 2026*

### ⭐⭐⭐⭐ Work well but be careful of the cover!!!
*by R***G on February 11, 2026*

These products work well; they alarm when they get wet and the remote sensor is terrific when you need it. The alarm is loud enough to hear and it gets pushed out to your phone and email. Ignore the comments saying that they don't stay connected to WiFi -- they're not SUPPOSED to. They re-establish their WiFi connection when they need to alert; otherwise it's shut off to preserve the battery. Battery life is good and the app is fine. The only real issue is that the shell cover which keeps water out is kept under pressure by a thick gasket and there is an electrical connector that must be tightly pressed for the external water leak sensor to work. All of this is secured by a tiny plastic hook that will break if you use a screwdriver to open the back. You MUST use the included prying tool or you will ruin the units when changing the batteries. They 100% should put a sticker on the back telling people to use the included tool to protect the unit!
