Understanding Plumbing Systems in Commercial Buildings

Plumbing is essential to the basic infrastructure of most buildings, but it’s not often taught in traditional degree programs. Also, specialized kitchen and laboratory requirements are increasingly costly and complex to install and maintain. By improving your understanding of the design, installation and operation of plumbing systems, including water piping, waste and vent, storm water, specialty gases, and equipment—you’ll be able to tackle these systems with ease.

• Mechanical system design engineers
• Plumbing estimators and installers
• Building code officials and inspectors
• University and government facility operators
• Commercial office building superintendents
• Equipment sales and technical representatives
• Construction managers and contractors
• Architects and project team consultants

This course has been approved by the State of WI Department of Safety and Professional Services (DSPS) for 20 hours for: Commercial Plumbing Inspector, Journeyman Plumber, and Master Plumber license holders.
