The Kidde Smart Water Leak Detector & Freeze Alarm is your first line of defense against potential water damage from a broken water heater, water leaking from the base of a toilet, a leaky drain, or frozen pipes. Simply place the home water leak detector under a sink, near pipes, or anywhere at risk for leaks or freezes. When the water leak sensor detects water or a significant temperature drop, it emits a series of 85 decibel alarms and sends a notification to your smartphone.
