Newly revised tapping guide for PVC pipe includes sections on: (1) Introductory material that applies to all types of tapping; (2) Direct tapping — where corp stop is screwed directly into threads in pipe wall — for branch line sizes up to 1-inch; (3) Saddle tapping — where corp stop is screwed into threads in metal saddle that wraps around pipe — for branch sizes up to 2-inch; (4) Sleeve tapping — where branch line is attached via flange on sleeve that wraps around pipe — for branch lines up to size-on-size.

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.
