Package of 3 Water Leak Detector Alarms with remote sensor (batteries included)

Three Water Leak Detector Alarms will sound when any water is detected by its remote water sensor.

A much better system because of its remote water sensor that wont get flooded out in a real leak

Unlike other all-in-one units our units buzzer will still work even if remote sensor is under water!

Detects the smallest amount of water to early warning before any major damage

Great for water heaters, sump pumps, under sinks, toilets, basements, aquariums etc.
