How do I pressure test drinking water installations with alpex?

Pressure testing must be carried out according to DIN EN 806-4 and the ZVSHK advisory leaflet "Leak Testing of Drinking Water Installations" (Dichtprüfungen von Trinkwasserinstallationen). Detailed requirements of pressure testing must be complied with depending on the test medium (water or air); please refer to pressure test reports water / air available in the download centre.
