Geevon’s water leak detectors are simple, single-purpose devices. Their job is to make a very loud noise when they get wet, and they do that job without any fuss or complicated setup. You get two sensors in the pack, which is the smart way to start covering common risk areas.

The 100dB alarm is the core feature. That volume is comparable to a motorcycle revving nearby. It’s a sharp, persistent sound designed to cut through background noise and walls. You’ll hear it from a basement laundry room while you’re upstairs. The sensors are IP56 waterproof, so a splash or spill won’t damage them, and they sit directly on the floor where water pools first. Two included AAA batteries power each unit for about a year of standby monitoring.

Placement is everything. These are ideal for under sinks, behind toilets, by water heaters, or on the floor near washing machines. They are strictly local alarms with no smart home connectivity. That keeps them affordable and reliable, but it means you won’t get a phone alert if you’re not home to hear the siren. For basic, audible leak detection, they provide straightforward peace of mind.
