After participating in this course, you will be able to:

  • Know the key design considerations for building plumbing systems
  • Apply codes and standards
  • Make sound materials selection decisions
  • Select specific equipment and corresponding piping
  • Understand why and when specialized piping is used

This course is a comprehensive review of plumbing systems design. It is intended for professional engineers and technologists responsible for plumbing system design in commercial, industrial, institutional, and multi-residential buildings.

Course topics include everything you need for designing a commercial plumbing system, from drain, waste and vent systems to domestic hot and cold water distribution systems. The course will cover sizing, layout and selection of all plumbing systems and their ancillary components, such as pumps and pressure booster systems, valves, piping, water heaters, and backflow preventers.
