A leak detector warns you if the sensors incorporated in the water detector come into contact with water. This way, you'll be informed quickly if, for example, there is a leak on your heating system or on your washing machine. Install the water sensor in your bathroom to get a notification when your bath floods, for example because you left the tap open. You can connect a water detector or leak detector to your existing alarm system. Make sure that the brand of your alarm system and leak detector match.
