The International Code Council is proud to distribute a helpful tool—Methods of Venting Plumbing Fixtures and Traps in the 2021 International Plumbing Code: Installation, Flexibility and Opportunity for Savings—to help expand your knowledge of the International Plumbing Code (IPC). The various approaches to venting that are permitted in the 2021 IPC are described in this handy reference tool authored by Lee Clifton, Senior Director of PMG resources at the Code Council. You will find that these venting provisions offer the installer and designer different paths to achieving an adequately vented system, which could result in cost savings along with ease of installation in different types of construction.
Chapter 9 of the IPC describes a variety of methods to vent plumbing fixtures and traps. The methods have been laboratory tested to determine sizing and installation requirements that provide proper venting to a drainage system. The venting methods have also been field-tested, establishing a long history of satisfactory service.
In this first of a four-part series of articles, the various approaches to venting that are permitted in the 2021 IPC are presented. To help keep in mind that “stack vents” and “vent stacks” are distinct, a short glossary of definitions is provided as well.
