Plumbing Venting: Decoding Chapter 9 of the IPC Paperback – October 7, 2014

Typically, I find that a lot of plumbing apprentices and even some skilled foremen have a hard time understanding venting. I have also noticed that new plumbing system designers will either do one of thee things: 1. They will under-vent a drainage system. 2. They will add illegal flat vents below the flood level rim of fixtures, (especially floor drains and floor sinks in commercial kitchens and mechanical rooms). or 3. They will over-vent a drainage system by venting every single fixture. For example, in a row of 8 water closets I have seen a vent placed on every single water closet. This is not only unnecessary, because it does not enhance system performance, but it is also more expensive to install. Instead of venting every single water closet, why not use a circuit vent? Don't understand circuit venting?... This book explains it in awesome detail.Bob Scott has done an excellent job of explaining plumbing venting in this book. He uses many isometric drawings to clearly show how each type of vent system works. He also uses pictures taken from actual job sites to show common mistakes, and the correct field installations. His descriptions and wording are clear and concise. You will have a much better understanding of venting after you study this book.Bottom line: If you are a plumber, plumbing designer, plans inspector, or building inspector, I would strongly recommend that you purchase this book. This is also an excellent companion to the ICC Plumbing Code Commentary. Knowledge of the craft is what separates your average plumber from a valuable and quality tradesmen. Don't hesitate, buy this book!

The International Plumbing Code (IPC) is shamefully obscure, misleading, and ambiguous on the topic of Venting. Especially for me, a homeowner and non-licenced homeowner who has many years of experience building and remodeling a few of my homes during my lifetime. I now have a simple mountain cabin, and I desired to install a single stack system. This book makes IPC intelligible on the topic and allowed me to design a code-compliant Drain Waste and Vent system. If I would have tried to follow posts and articles that proliferate on the web, I would not have been able to appropriately design the system. If you are not a licenced plumber and working with DWV, then this book might be invaluable to you too.

Book is very helpful! Bob Scott taught me a lot over the years. This is the most helpful book on Plumbing venting that I have ever seen published! This book will make any plumbers life easy well written extremely well Illustrated! Myself my brother and my father are all and photographs in this book. Should be a book every Apprentice should go out and buy .

Good reference. But could use more actual examples of three- level plumbing ( basement and two stories).

Well written, copious and well taken photographs/illustrations a great reference tool for the Plumbing professional and future up and coming Plumbing apprentice/tradesman! Thank you Bob Scott for taking the time in creating this very "needed" and welcomed Plumbing reference book.

Pretty good book for a plumber. This is not for house flippers or anyone who can not already read a plumbing code book. It's great for someone looking to actually understand drain, vents and waste. Good for plumbing and or engineering exams.

Pretty basic review. Nothing great, has good pictures.
