This document has been developed by the Uni-Bell PVC Pipe Association for design and installation of PVC fittings where solid-wall PVC pipe is used in non-pressure applications. The guide provides information on the wide range of fittings that are available for various dimension ratios and outside diameters of PVC pipe through 60-inch. Also included is information on installation practices.

Longevity of PVC sanitary sewer and storm drainage systems can be enhanced by use of PVC appurtenances that are not subject to corrosion.
