Topvico Water Leak Sensor Detector – 120dB Flood Alarm for Basements, RVs, Battery-Powered 3-Pack

Protect Your Space from Hidden Water Threats

Moisture can creep into unwanted places, turning a small drip into a costly problem. Topvico’s Water Leak Sensor Detector is a self-contained guard that works without a hub, delivering fast alerts when moisture is detected. The result is a clear signal you can act on, whether you’re at home, away, or in transit with an RV.

This device prioritizes visibility, responsiveness, and ease of use. It’s designed to serve both everyday rooms and hard-to-reach corners where leaks are easy to miss—because early awareness matters.

Key benefits that support quick action

• Unmissable alerts — the 120dB siren sounds until the area dries or you switch it off, helping you notice leaks promptly.
• Sensitive and reusable sensor — a premium 24K plated detection board ensures reliable response; after drying, you can reuse the sensor.
• Flexible mounting — comes with double-sided adhesive and two mounting styles to fit walls, floors, or compact RV spaces.

Extendable reach to cover hard-to-see spots

The unit ships with a 37.8-inch detection cable and can be extended with standard electrical wire to over 150 feet. Use it near sump pits, basements, water heaters, laundry areas, kitchens, or RV compartments to monitor moisture progression.

Power-smart, maintenance-light operation

Designed for efficiency, the device runs on a single 9V alkaline battery (not included) with optimized standby mode that can last for up to two years, depending on use. Fewer battery changes means less maintenance while keeping protection in place.

Practical setup and what you get

• Three-pack packaging lets you deploy in multiple zones for broader coverage.
• After a trigger, simply dry the sensor board and reuse it for continued monitoring.

Note: this sensor provides alerts and coverage, but it does not guarantee outcomes. It offers a proactive signal to help you respond quickly and potentially limit damage when leaks occur.

Real-world uses

Common placements include basements near sump pumps, laundry rooms, kitchens, near water heaters, and RV storage compartments. By situating detectors where moisture tends to collect, you can build a practical defense against unexpected leaks.
