Professional flood protection. No more worries about sudden water leaks while doing your laundry! With the Scanpart Uni-Water Stop, you can now take a leisurely walk or go shopping while your washing machine is running. The water stop protects your rooms from flooding that can occur due to a faulty hose or washing machine drum. As soon as the sensor placed under the machine detects a water level of 0.5 mm, the water supply is automatically shut off. The water stop is powered by a supplied battery (LR 6). Please replace the battery after its expiration date to ensure proper functionality.
