Waterproof system (WPS)

Additional safety
WPS also features a double solenoid valve directly at the stopcock. If the first valve is faulty, the second closes the inlet. The double skinned inlet hose provides the highest level of protection: in the event of a defect in the inner hose, water flows down the outer sleeve into the sump. Like the WCS, the WPS also features intelligent sensor technology: if a leak is detected, the water inlet is closed off.
Features depend on model
