A broken hose at the washing machine or a leaking pipe at the water tap. Even if there is only a small leackage it can cause a big damage. The POPP Water Leackage Sensor protects you from all these scenarios. As soon as the device detects water at his probes an acoustic alarm is triggered. Additionally, the LED starts blinking and the alarm signal is sent to the Z-Wave gateway. Because of that, you receive a message on your smartphone and you can act immediately even when you are not at home. Therefore you can prevent high damages caused by water.

Connected to other smart devices like the POPP Flow Stop you can even turn off the water automatically, if there is a leakage in a water pipe.


The POPP Water Leakage Sensor can be placed underneath a washing machine or a sink. If there is not enough space for the main device you can use the included sensor cable with extra wall mounting plate. The sensor is water resistant and floats (protection class IP44). Thus, it is also suitable for outdoor use.

The recommended way to install the device is to mount the mounting base on the lower part of the wall closed to the point of water leakage control. When mounted on a wall the device can be attached using the double sides tape on the backside of the device. However it is recommended to screw the device holder to the wall.
