HS10S Water Supply Unit

HS10S combination water supply units integrate a non return valve with test point, reverse rinsing fine filter, pressure reducing valve and shutoff valve in one appliance. They ensure a continuous supply of filtered water. The fine filter stops the ingress of foreign bodies, for example rust particles, strands of hemp and grains of sand. The non-return valve protects the mains water system against back pressure, back flow and back siphonage of health threatening liquids.


The pressure reducing valve prevents overpressure damage and reduces water consumption. All individual units correspond to the requirements of current DIN/DVGW specifications. Technical features of each unit also apply to the combination assembly.
