"Crosslinked polyethylene (PEX) tubing has been used for water service and building supply line applications across North America for more than 25 years. AWWA C904, the controlling industry standard specification for this category of product, was originally published in 2006. The latest revision in 2022 added new requirements that help ensure that PEX water service tubing will meet and exceed customer expectations for protecting the health, safety, and welfare of water customers while delivering excellent durability and reliability.
Register at expo.aspe.org This session will explain the technical requirements of AWWA C904 and how this standard can be used for guidance during the design of PEX water service lines. It will introduce the most important properties of PEX tubing for this application and describe new joining systems that are now permitted for use. Finally, it will introduce Appendix A, which covers installation topics such as bending, joining, thawing, HDD usage, testing, and disinfection."
