Water Leak Detector Alarm | 110dB Flood Sensor Alert

Never be caught off guard by an unexpected water leak again. The Water Leak Detector Alarm is a simple, automatic sensor that sounds a powerful 110dB alert the instant it detects moisture — giving you precious time to act before water causes serious damage to your home or property.

No programming, no apps, no buttons. Just place it anywhere you're concerned about water and let it do the work.

Why You'll Love It

Frequently Asked Questions

Q: Does the water leak alarm need to be plugged in or connected to Wi-Fi?

A: No. The water leak detector is completely standalone. It runs on a single 9V alkaline battery (not included) and requires no Wi-Fi, hub, or programming. Simply insert the battery, place the unit where you want to monitor for leaks, and it's ready to detect water instantly.

Q: Where are the best places to put a water leak sensor in my home?

A: Common high-risk areas include under the kitchen or bathroom sink, beside washing machines, near water heaters, under refrigerators, in basements, and around sump pumps. Anywhere water could accumulate unexpectedly is an ideal location for this flood alert sensor.

Q: How loud is the 110dB alarm — will I hear it from another room?

A: At 110 decibels, the alarm is approximately as loud as a power saw or a rock concert. It is loud enough to be heard clearly throughout most homes, ensuring you get an immediate alert even if you are not in the same room as the sensor.

Q: How long does the battery last in standby mode?

A: Under normal standby conditions (no alarm triggered), a fresh 9V alkaline battery typically lasts up to one year, making ongoing maintenance very low effort.
