Inspecting Commercial Plumbing Systems Online Course

A commercial plumbing inspection includes water supply and distribution systems, fuel supply and distribution systems, and the plumbing fixtures, appliances, and equipment connected to them. This course explains how these systems are designed, installed, and intended to operate, along with inspection procedures, safety practices, and commonly reported conditions. Each system is taught by tracing the service from its main connection through the building’s distribution points, helping commercial property inspectors perform efficient condition assessments of plumbing systems in commercial buildings.

The course also reviews how commercial plumbing systems differ from residential systems and what inspectors should expect when assessing properties with different occupancies, uses, and water demands, including multi-tenant and multi-building properties. Concepts are organized to help inspectors understand plumbing systems as a whole and apply the knowledge in the field. You’ll also learn about the commercial property inspection standards of practice and plumbing design principles reflected in the IBC, IFGC, and NFPA.

Upon successful completion of this course, the student will be able to:

• apply the ComSOP inspection scope to plumbing inspections;
• demonstrate an understanding of the differences between commercial and residential plumbing systems;
• identify, describe, and report on plumbing systems and components, including:
  • public and private water supply systems and components;
  • water service and distribution piping throughout the building;
  • water and fuel safety components installed on piping, equipment, and appliances;
  • backflow prevention methods and cross-connections;
  • wastewater and sanitary drainage systems;
  • drain, waste, and vent systems and traps;
  • specialty drainage interceptors used in commercial buildings;
  • fuel supply and distribution systems (natural gas, propane, fuel oil, etc.);
  • restrooms and plumbing fixtures; and
  • water heaters;
• apply inspection considerations for different commercial building types, including multi-tenant and multi-building properties; and
• demonstrate an understanding of common defects and safety concerns observed during commercial plumbing inspections.
