What Is a Water Leak Detector?
A water leak detector is a small device. It senses water where it should not be. When it finds water, it sends a warning. Some detectors beep loudly. Others send alerts to your phone. This quick warning helps you stop leaks early.
Detectors usually sit on the floor or near pipes. When water touches the sensor, the alarm goes off. Some detectors work with smart home systems. You can check them from anywhere.
Why Protect Your Basement and Bathroom?
