Description
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.

Who Should Attend
Plumbing Designers • Mechanical Design Engineers and Technologists • Plant Supervisors • Maintenance personnel • Building Officials and Inspectors • Operators and Contractors
