Loud Water Leak Alarm – 90dB Drip & Overflow Sensor (Kitchen, Bath, Basement)

The leaks that cost the most are the quiet ones: a drip under the kitchen sink, a slow seep behind the toilet, a washer hose that lets go while you're at work. By the time you see it, the cabinet floor is soft and the drywall is stained.

This alarm sits on the floor where water would show up first. The moment water touches the sensor probes, it sounds a loud 90dB alarm so you catch the leak while it's still a towel job, not a contractor job.

Where to put one

• Under the kitchen and bathroom sinks
• Behind toilets
• Next to the washing machine and dishwasher
• Beside the water heater and sump pit in the basement

Why it's worth it

• Loud: 90dB alarm you'll hear from another room
• Catches drips and overflows: trips with about 1mm of water on the floor
• No install: set it down and you're done, no tools or wiring
• Waterproof: IP65 rated, floats if water gets deep
• Long battery life: runs on 2 AAA batteries, about 12 months
• Stops on its own: alarm quiets once the probes are dry
• Expandable: 433MHz, works with KERUI alarm systems (W181, W184, W204)

Buy the 3-pack or 5-pack to cover every water spot in the house.
