Additional safetyWPS also features a double solenoid valve directly at the stopcock. In the event that the first valve is defective, the second one closes the inlet. The sheathed inlet hose also ensures the highest level of safety: in the event of damage to the inner hose, water flows down the outer sleeve into the floor tray. Like the WCS, the WPS also features intelligent sensor technology: leakages are detected and the water intake is terminated.
