Water Leak Sensor To Prevent Expensive Flood Damage
Protect your home from expensive leaks and floods by installing a 3-Series Water Sensor near water heaters, drain pans, and underneath sinks. The Water Sensor and Water Leak Detector are small, easy to use, and fit almost anywhere. The Centralite water sensor is directly on the ground, and it will notify you when it detects the presence of water.
How does a water Leak sensor work?
The workings of the water leak sensor are pretty straightforward. The series of exposed parallel conductors act as variable resistors whose resistance varies according to the water level. The change in resistance corresponds to the distance from the top of the sensor to the surface of the water.

Water Leak Detector Superior Range and adaptability
It automatically shuts off the water supply to your home in case of a leak.
If the 3-Series Water Leak Sensor detects water, it can trigger the whole-home water shut-off valve to disconnect the water supply. This protects your smart home against leaks and flood damage, even when you’re away from home or unaware that there’s a problem.


Ensure that A/C drain pans don’t overflow.
With optional remote leads, you can place the water leak sensor in areas where there is typical standing water. A/C drain pans contain some water under specific operating conditions, but with the 3-Series Water Sensor, you can be notified when the water reaches an unacceptable level.
Use The Water Sensor to Prevent flooded basements when sump pumps fail.
Many homes with a basement have water entry issues requiring automatic sump pumps to remove water. When these pumps fail, the rising water level can trigger notifications using the 3-Series Water Sensor.

Do-it-Yourself Installation
The 3-Series Water Leak Sensor is designed to be installed by anyone, not just professionals.
Most users can install and pair the Centralite water leak sensor in about 10 minutes.

Open the hub for joining and pull the plastic tab from the device.
Place on any surface near a water source.
