Application technology for metallic pipe installation systems > Clean drinking water is a prerequisite for our health. It contains essential minerals and elements and is used for the preparation of food, for cleaning objects and for personal hygiene. The common goal of the planner, trades- person and supplier is to provide drinking water to every tap in sufficient quantities and of an acceptable quality. Drinking water is a perishable foodstuff. Its constitution changes in the drinking water installation, e.g. through contact with materials, heat or periods of stagnation with the relevant...
