Per- and poly-fluoroalkyl substances (PFAS) are a group of over 4,700 compounds made up of fluorinated carbon chains. PFAS are commonly used across various industries such as aerospace, automotive, construction, cosmetics, and electronics, and are found in products like firefighting foam and non-stick cookware. Some PFAS compounds have been identified as harmful to human health. This document aims to reassure utilities and their customers that PVC pipes do not contribute to the presence of PFAS in drinking water. Addressing PFAS in Drinking Water PFAS can contaminate drinking water due to widespread environmental pollution. In response, the U.S. Environmental Protection Agency (EPA) has established national primary drinking water standards for six types of PFAS, limiting the permissible amounts in potable water systems. PFAS: Not From PVC Materials or Manufacturing PVC (polyvinyl chloride) pipe is primarily made from PVC resin, combined with other ingredients to form a compound that is...

This document has been developed by the Uni-Bell PVC Pipe Association to serve as a comprehensive guide for the design and installation of gasketed PVC fittings. These fittings are used in various applications, including potable water systems, force mains, pressure irrigation, and reclaimed water systems. The guide specifically addresses gasketed PVC fittings compatible with different dimension ratios and outside diameters of PVC pipes up to 60 inches. It is important to note that this document does not cover solvent-welded or fusible PVC fittings. Types of PVC Fittings The following are the various types of fittings available for use with gasketed PVC pipes: Tees: These fittings have an outstanding leg positioned at a 90° angle to the main pipe, allowing for the creation of a T-shaped junction. Crosses: Crosses have two outstanding legs that are opposite each other, forming a plus (+) shaped intersection. Bends: Bends are used to change the direction of the pipeline. Standard angles a...
