Pro Tip

Place sensors in the most vulnerable areas where water damage typically starts: under kitchen and bathroom sinks, behind toilets, near water heaters, washing machines, and dishwashers. For maximum protection, position them in the lowest points where water would naturally collect. The 30-50 metre range means you can monitor your entire home from a single Zigbee hub.

Social Proof

Leading home technology experts report that water leak detectors provide "plenty of warning of a localized water leak" and can help homeowners "reduced average claim costs by £4,000 due to lower loss frequency and severity". Industry studies show that "escape of water damage is one of the most common types of domestic property damage claims—more than fire or theft", whilst data from smart sensor manufacturers demonstrates significant reductions in reported water damage cases, with users consistently praising the "timely alerts and reliable detection" that help minimize water damage and protect homes. UK insurance providers recognise that early water detection can "save thousands of pounds in damage".

Perfect for homeowners, renters, and landlords who understand that prevention costs far less than repair. This reliable sensor provides peace of mind whether you're protecting a single flat or managing multiple properties.
