Geevon 2 Pack Water Leak Detectors for Home, 100dB Loud Water Sensor Alarm Leak Detectors with Drip Alert for Kitchen, Basements, Laundry Rooms, IP56 Waterproof(Battery Included)

Great value, easy set up, works great. Cheap enough to use in so many places. We have had water detectors for years.. Saved us money for sure in previous years to use water alarms and price is cheaper than they were years ago. .We use under out central AC Unit, in the hot water heater closet. Great behind toilet and under the water supply line for two types of leak. Getting more for gifts. Great under your sinks, washing machine or anywhere water is in the house. These detect well! This had a bonus of a top drip detector that I discovered while reading directions. place under drain pipes for double notification type. This type is not wifi. ONLY complaint is that the instrction manual print is so tiny I had to use contacts, readers, and a magnifying glass to read. so, To use pull the clear tab if any and sit flat to operate. For my check of the unit, Stick a barely damp finger on top of the slash area to test but not too damp. it has to be dry to stop alarming. Then I put a few drops of water in a plate and sit the unit on top of it to check. Dry off to stop alarm.
