Course Description
Introduces the principles and hazards of backflow prevention. Reviews different types of vents that can be installed in a drain, waste and vent systems, sewage pumps, sump pumps, corrosive waste products, and safety issues. Includes instruction on sizing drains, waste, drain-waste-vent systems (DWVs), and indirect waste piping. Provides hands-on lab work on plumbing with waste, water, gas, and vents. Designed for registered apprentices in the plumbing trade.
Course learning outcomes
