Protection against flooding
The Waterproof System protects against water damage with a dual solenoid valve at the stopcock. If the first valve does not close, the second one interrupts the water intake. The double skinned inlet hose provides the highest level of protection: In the event of damage to the inner hose, water flows through the outer sleeve into the sump. Intelligent sensor technology detects leaks and in an emergency also stops the intake of water.
