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).

Copper (drinking water)Galvanized steel (drinking water/gas)PP/PE (wastewater)Cast iron (drainage, older buildings)First multilayer composite pipes (from approx. 1995)
  • Contact corrosion in copper-steel connections
  • Pitting corrosion on copper pipes (aggressive water)
  • Brittle plastic seals
  • Leaking soldered connections
  • Outdated insulation (may contain asbestos)
  • Copper always BEFORE steel in flow direction (galvanic corrosion)
  • For mixed materials: GEBO brass clamp connectors as transition
  • Replace old seals when opportunity arises
  • MiniGebo ideal for radiator connections to copper
