What does the term 'backflow' mean?

• A. The flow of water into a pump
• B. The reverse flow of water in a plumbing system
• C. The normal flow of water through pipes
• D. The flow of water from a faucet

Answer: (B)

The term 'backflow' refers to the reverse flow of water in a plumbing system. This usually occurs when the pressure in the plumbing system is reduced, leading to water flowing backward into the source supply. Backflow can pose serious risks, as it can cause contaminated water to mix with potable water supplies, potentially leading to health hazards. Understanding backflow is crucial for pipefitters and plumbers because it emphasizes the necessity for proper system design, installation of backflow prevention devices, and ongoing maintenance to ensure safe and clean water systems.
