Welcome to John’s Blog. Answers to frequently asked questions are periodically posted here. The objective is to share information about PVC pipe with readers as well as with utilities, design engineers and pipe installers. The blog provides the latest information on PVC pipe design, installation, and application for water and wastewater infrastructure projects.
We encourage you to connect to John’s Blog by bookmarking this page or by connecting our Technical Blog to your RSS feed program.
John Houle: Senior Technical Consultant, PVC Pipe Industry

The PVC Pipe Association has published a document titled “Guide for PVC Pressure Fittings.” The Guide contains information on PVC fittings standards and discusses available products and their applications. Also included are a design section focused on different methods to prevent pipe and fitting movement as well as an installation section that provides essential information for efficient construction of an all-PVC pipeline. PVC fittings are available for the full range of AWWA C900 PVC pipe. Two manufacturing processes are used: injection-molding for 4- through 12-inch sizes and fabricating for 4- through 60-inch sizes. The primary advantage of PVC fittings is that PVC is not subject to corrosion. Sewer forcemain designers will especially benefit from the PVC fittings guide due to hydrogen sulfide corrosion of metallic and concrete fittings. Click here for the Guide.
