Underground and exposed piping shall be flow tested to determine the internal condition of the piping at a minimum ____ intervals?

Underground and exposed piping shall be flow tested to determine the internal condition of the piping at a minimum ____ intervals?

• A. 1 year
• B. 5 year
• C. 10 year
• D. 7 year

Answer: (B)

Periodic checks of underground and exposed piping are done to verify the inside of the pipes is still in good condition and capable of delivering the required flow. Flow testing helps reveal internal issues like corrosion, scale, or obstructions that aren’t visible from the outside, ensuring the system will perform when needed. The minimum interval is five years. This interval provides a practical balance: it’s frequent enough to catch developing problems before they worsen, but not so frequent that testing becomes unnecessarily costly for piping that isn’t readily accessible. Shorter intervals (like yearly) aren’t typically required for these sections, while longer intervals (such as ten years) could allow hidden deterioration to go undetected.
