Introduction to Plumbing
This book is a guide to good plumbing practice. Even if you've
had little or no experience with plumbing systems, you should have
no difficulty understanding what's explained here.
The text covers the basic principles required to plan, install,
and maintain common plumbing systems in residential and light
commercial buildings. An understanding of the plumbing code is
essential, so code requirements are discussed throughout this book.
You'll find questions at the end of each chapter to help test your
understanding of the ideas presented. Study the text carefully to
master the fundamental principles behind each question before you
turn to the answer in the back of the book.
This book will help you select the materials, pipe sizes, and
methods of installation generally accepted as correct by most
This manual explains everything you need to know to
install plumbing on nearly any residential or light commercial job.
But it doesn't go into highly technical areas or specialized
plumbing and piping such as hydraulic and pneumatic systems that
might just be confusing.
Nearly every city, county and state has adopted a plumbing code
to protect the health, safety, and welfare of its people. Building
departments enforce these codes and arrange inspections of plumbing
work as it's completed. As a professional plumber, you can expect
that nearly all of your work will have to meet code requirements and
pass an inspection.
The plumbing code is a law intended to be enforced, not a set of
directions intended to be followed. That means you shouldn't expect
to learn the plumbing trade by reading the code. Still, every
professional plumber (whether apprentice, journeyman, master or
maintenance plumber) will have to refer to the code at least
occasionally. You need a copy of the plumbing code that's enforced
in the communities where you do work. If your local building
department really wants to help you follow the code (rather than
just enforce the code against you), they'll have copies for sale
across the counter at the building department.
Please note that homeowners who install plumbing must follow the
same rules as professional plumbers. Homeowners are subject to the
same penalties as licensed plumbers who don't get the required
permits and comply with the code. Good plumbing doesn't depend on
who does the work, but on how it's done.
Plumbing codes vary. Every city, county and state can adopt any
plumbing code that they want to adopt. Many adopt one of the model
codes but amend certain sections. Others follow one of the model
codes but not necessarily the latest version of that code. No matter
what code your community has adopted, the basic principles of
sanitation and safety are about the same.
You should understand clearly that this manual isn't the plumbing
code. You'll have to refer to your local code from time to time. But
what you learn in this book will meet code requirements nearly
anywhere in the U.S. or Canada. The minor differences between model
plumbing codes are emphasized throughout this book. They'll be
apparent as you read and compare sections of this book with your
Some codes require that only a licensed plumbing contractor do
new or extensive remodeling work. However, most codes allow
homeowners to do any type of plumbing work in their existing home.
Some codes also permit homeowners to install plumbing in a new house
if the owner can show a basic ability to do the work without
What About Plumbing Permits?
Codes require a permit for all plumbing work except repairing
leaks, clearing obstructions in sewer lines or waste pipes,
repairing faucets or valves, or cleaning septic tanks. When a permit
is required, the permit must be posted at the site and available at
all times for the plumbing inspector.
You can't cover or conceal plumbing work in any way until the
plumbing inspector has checked the work for compliance with the
code. As the permit holder, you have to notify the plumbing
inspector when the work is ready for test and inspection.
Inspections are classified into three categories for a one-story
- ground roughing-in
- tub set and interior water piping
For a two-story building, a fourth inspection is required. It's
called the "topping out" inspection. All rough piping must be
inspected above the first floor and up to and through the roof.
After you complete the permitted work, don't wait more than 30 days
before you request the final plumbing inspection. Also the building
or construction can't be used or occupied until after the final
inspection is made. These inspections will be discussed in detail in
later chapters so you know how to prepare for each inspection.
