This product contains two devices: Smart water detector and Shutoff valve..
The smart water detector is located at the top of the cistern and it is designed to have standard dimensions to fit any cistern. Its function is to inform the valve if the water level in the cistern reaches its maximum level.
The shutdown valve is located on an inlet pipe that fills the cistern. This device serves to shut down the water supply if the smart water detector detects an increase of water in the cistern, compared to its normal level.
