Understanding Drainage and Water Distribution Systems Course

 Understanding Drainage and Water Distribution Systems is a free online course which is designed for anyone who wants to get a better understanding of the drain, waste, vent, and water distribution systems. Within a building, these systems are installed and maintained by plumbers. A thorough understanding of how they work is, therefore, a crucial requirement of a plumber's job.
