Old Building before 1970
before 1970
Buildings before 1970 often have lead pipes (drinking water), galvanized steel, cast iron drainage. Lead pipes MUST be replaced. Mixed installations and outdated standards are to be expected.
Old Building 1970–2000
1970–2000
Buildings from this era have copper (drinking water), first plastic pipes (PP, PE), galvanized steel. Watch out for mixed metal corrosion (copper-steel contact).
New Building from 2000
from 2000
Modern buildings use multilayer composite pipe, PE-X, stainless steel and copper. Focus on energy efficiency, hygiene (TrinkwV) and smart home integration.
Industrial Building
variable
Industrial buildings have large pipe dimensions, flange connections and special media (chemicals, steam, compressed air). Focus on pressure ratings, material compatibility and safety.
Agriculture
variable
Agricultural applications: PE pipes underground, irrigation, drinking water for livestock. UV resistance is important for above-ground lines. Often large dimensions.
