System separation to DIN EN 1717

The INTEWA system separator "SEPAMAT" isolates the drinking water system from the consumer. It protects drinking water against contamination caused by backflow of pollutants from the consumer point of use. System separation is installed between the municipal drinking water supply and one or more fixtures. These must be separated in accordance with Category 5 of the current drinking water regulations contained in DIN EN1717.
