A method for preventing corrosion in water supply pipes has a circulation system in which water is continually moving even when none is drawn off

摘要

The outlets (Z) in a household supply network are supplied from a source (WQ) and a heated system (WWB) from a cold water inlet (KW) and unused water is fed back through a filter (F) and pump (UW) to the source point in a closed circuit (WKL) by a control unit (ST). Additives (MB) may be added (DO).
