2-Pack Wireless Water Leak Detector with 110dB Audio Alert

Never be caught off guard by an unexpected leak again. This 2-pack of wireless flood sensors instantly detects water leakage and triggers a powerful 110-decibel audio alarm alongside a simultaneous flash alert — loud enough to be heard throughout the entire home. Compact, battery-operated, and completely wireless, these detectors are the smart, low-cost way to protect your home from costly water damage.

Key Features

Powerful 110dB Alarm + Flash Alert: Dual sound-and-light notification system ensures you never miss a leak, day or night, 24/7, 365 days a year.

Fully Wireless & Easy to Set Up: No wiring or installation required — simply insert batteries (not included) and place the detector wherever you need it.
Waterproof & Floatable Design: Fully sealed and waterproof interior. If the water level rises above the detector, it automatically floats on the water's surface and continues alerting.
Detachable & Portable: Compact, lightweight ABS construction makes it easy to place in tight spots — under sinks, near appliances, or in crawl spaces.
Wide Application: Ideal for basements, bathrooms, kitchens, boiler rooms, near washing machines, water heaters, steam generators, water towers, ceilings prone to leaks, and more.
Value Pack: Comes as a 2-piece set for comprehensive coverage across multiple areas of your home.

Frequently Asked Questions

Q: Does the water leak detector come with batteries included?

A: No, batteries are not included. The water leak detector is battery-operated, so you will need to purchase compatible batteries separately before use. Once batteries are inserted, the device is ready to use immediately — no additional setup or wiring required.

Q: Where is the best place to install a water leak detector?

A: These flood sensors work best when placed directly on the floor in areas prone to leaks, such as basements, under bathroom or kitchen sinks, near washing machines, behind dishwashers, or next to water heaters. Position the detector so its two bottom contact points can come into direct contact with any pooling water.

Q: Is this water leak detector truly waterproof?

A: Yes. The detector features a fully sealed, waterproof interior design. If the water level rises higher than the sensor itself, the unit is designed to float on the water's surface and continue sounding the 110dB alarm, ensuring continuous alerting even in significant flooding situations.

Q: How loud is the alarm on this flood sensor?

A: The alarm reaches 110 decibels — roughly as loud as a power saw or car horn at close range. This level of volume is sufficient to be heard throughout most homes, ensuring that you'll be alerted quickly regardless of where you are in the building.
