Frequently Asked Questions

Q: Does the water leak sensor alarm require any installation or wiring?

A: No installation or wiring is required. This is a fully standalone, battery-powered water leak sensor alarm. Simply insert a 9V alkaline battery (not included), place the sensor probe near a potential leak source, and it's ready to go. No hub, Wi-Fi, or technical setup needed.

Q: How loud is the water leak alarm, and will I hear it from another room?

A: The alarm produces a powerful 110dB sound — roughly equivalent to a chainsaw or loud concert — which is clearly audible throughout most homes, including from adjoining rooms or a floor above.

Q: Where is the best place to position the water leak sensor?

A: Place the sensor probe directly on the floor in areas prone to leaks or flooding: under sinks, beside toilets, next to washing machines, near water heaters, or in basements. The 1-metre probe cable allows flexible positioning so the main unit can sit in a dry, accessible spot while the probe rests in the detection zone.

Q: Is the water leak sensor reusable after it has been triggered?

A: Yes. Simply dry off the sensor probe and the alarm will reset, making it fully reusable for continuous protection.
