Suggested uses are near or under sump pumps, toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks and any other location subject to water leaks and flooding.
Early-Warning Notifications: Receive real-time early-warning notifications (in the form of smartphone banner alerts, limited SMS/text messages, and emails) and protect your home and property from water damage; Due to the water-tight and submersible design of the original Water Leak Sensor, an internal sounder/siren would not be heard outside of the water-tight housing. For an audible alarm, consider our Siren Alarm or consider the Water Leak Sensor 2 which has a built-in sounder.
