Benefits of Water and Flood Sensors

Water and Flood Sensor FAQs

How does a water leak detector work?

Most water sensor detectors include two parts – the sensor and the transmitter. The transmitter is often placed within a certain range of the sensor to send a signal of water is detected. The flood sensor often includes metal probes that will alert the transmitter if water touches them. Oftentimes, an alarm will sound and a mobile alert will sound.

Where can I install a water leak detector?

Most water sensor detectors can be installed anywhere there are potential water leaks such as next to dishwashers, laundry rooms, toilets and refrigerators. Pay attention to your provider’s installation instructions for the best water detection and places to avoid setting up sensors. Keep in mind that some sensors may not be placed on carpet or outdoors.

How many water sensor detectors do I need?

The number of water sensor detectors you need depends on your home and potential water damage. For instance, leakSMART can support up to 30 sensors. Start by making a list of areas that you’d like to monitor for potential water leaks and damage. If you’d like to connect sensors to cover larger areas, such as the kitchen or laundry room, add a sensor cable for expanded water detection.
