This powerpoint presentation begins by providing a brief overview of dezincification in premise plumbing, along with the current state of knowledge on factors known to affect dezincification, effects of the brass alloy and water chemistry, and emerging issues of environmental factors. The experimental plan included: role of the alloy in an aggressive water; role of galvanic couples between brass and copper pipe; and, flow electrification for dezincification including the effect of different flow conditions, and the effect of the aluminum core in composite PEX. Includes tables, figures.
