Why is flushing important in systems to manage Legionella risks?

• A. To decrease flow speed
• B. To remove stagnant water
• C. To maintain temperature
• D. To increase system pressure

Answer: (B)

Flushing is crucial in managing Legionella risks primarily because it serves to remove stagnant water from the plumbing systems. Stagnant water is a breeding ground for Legionella bacteria, as it often provides optimal conditions for growth—namely, warm temperatures and a lack of water movement. By flushing the system, you ensure that any water that has been sitting still is expelled and replaced with fresh water that is less likely to harbor bacteria. This process helps minimize the potential for Legionella proliferation, thereby reducing the risk of exposure to individuals using the plumbing infrastructure. Regular flushing is an essential part of maintaining a safe water system, particularly in larger plumbing networks where water may not circulate frequently enough to prevent stagnation.
