The WaterStop offers reliable protection against unpredictable water leaks and is recommended as an addition to any built-in water filter. It is installed directly on the cold water angle valve and protects all downstream devices and installations – regardless of the cause of water damage.
As soon as the floor sensor (1 sensor) comes into contact with water, the solenoid valve immediately closes the water supply and emits an audible warning signal. This effectively prevents damage caused by pressure surges, material fatigue, installation errors, or leaks – even if no one is on site.
Dimensions control unit (electronics): 7.2x3.6x5.6 cm
Dimensions solenoid valve: 5.5x5.0x2.5 cm
Note: This product is included with some reverse osmosis systems. Even though it works well, we recommend the HydroStopper, as it has 2 sensors and separating and restoring the water supply is more intuitive. Furthermore, we have already been able to test it on over 1000 systems.
