Abstract
A drinking water installation is made up of a source of drinking water and equipment for delivering the drinking water. In the equipment for delivering drinking water, a copper-zinc alloy which does not contain lead or bismuth is used. This alloy has a copper to zinc ratio of from 1.3 to 2.0 and contains at least one additive for improving the properties of the alloy. This alloy possesses superior machinability properties and yet does not pose the potential toxic hazard that lead- or bismuth-containing alloys do.
