Plumbing Design Notes _ Part 1

Introduction

This course offers engineers, designers, and students with practical guidance on plumbing system design. The notes summarize key requirements from the International Plumbing Code (IPC). highlight common industry practices, and explain design considerations for fixtures, piping, hot water systems, and pressure requirements.

Learning Objectives

1.       By the end of this module, participants should be able to:

2.       Identify applicable plumbing codes and state amendments relevant to design projects.

3.       Apply IPC tables to calculate fixture units, flow rates, and pipe sizes.

4.       Recognize common fixture supply sizes, installation heights, and distribution strategies.

5.       Explain the role and placement of backflow preventers, water meters, and zone valves.

6.       Evaluate pressure requirements, friction losses, and pump sizing criteria.

7.       Describe hot water supply strategies, including mixing valves and recirculation systems.

8.       Apply drafting conventions for plumbing layouts and fixture connections.

9.       Understand practical considerations for domestic plumbing such as insulation and routing.
