Abstract
A process for treating brass plumbing components to reduce leachable lead when the component is subsequently exposed to water includes exposing the brass component in an aqueous solution containing a desired concentration of chloride and pyrophosphate, with the chloride ion promoting the dissolution of lead from the brass component and the pyrophosphate ion preventing saturation of the solution with lead insuring continuation of the dissolution process.
