Two articles reprinted from Materials Performance, August 1993. The first tells how to avoid pitting attack (cold and hot water), concentration cell, dezincification, erosion and galvanic corrosion. Materials selection, system design and chemical treatment techniques are examined. The second article provides an analysis of water treatment techniques used sucessfully by water utilities or dwelling owners, including the addition of hydrating line, caustic soda, ash or a silicate to the distributed water.
