Grohe Original WAS connection valve: with shut-off hose connection
With the original WAS connection valve from Grohe, you can quickly and easily connect appliances such as washing machines with a hose. This connection can even be shut off. It is intrinsically safe against backflow and is equipped with a backflow preventer, which prevents the used water from flowing back into the drinking water installation. The chrome-plated StarLight surface additionally ensures a shiny appearance.
