AWWA issues report guide
The American Water Works Association (AWWA) has issued a report to be used as reference guide for the installation of cross-linked polyethylene (PEX) pipe. The report was written by the AWWA C904 Subcommittee of the Standards Committee on Polyolefin Pressure Pipe and Fittings and describes methods of manufacturing, material properties and the capabilities of the flexible pipe known for durability, performance characteristics and installation efficiency.
The information in the 12-page report can now be readily used by any municipal engineer or plumbing system designer for reference or for inclusion in a proposal. The report also examines PEX pipe's temperature and pressure capabilities, as well as its resistance to freezing, chlorine, corrosion, UV and chemicals.
Primary authors were PPI staff members Camille Rubeiz, P.E., subcommittee chair, and Randy Knapp, plus Sarah Chung of Jana Laboratories; Gary Morgan of Watts, Inc.; Lance MacNevin of REHAU, Inc.; Gary Runyan of Zurn PEX, Inc.; and John Fishburne of the Charlotte-Mecklenburg Utilities, N.C., and committee chair.
