Underground piping shall be tested once every how many years before a representative of the fire department?

• A. 5 years
• B. 10 years
• C. 15 years
• D. 20 years

Answer: (B)

Periodic testing of underground piping is done to verify there are no leaks and that the system remains tight over time. The required interval is once per decade, with a fire department representative witnessing the test to confirm proper procedure and provide official sign-off. This 10-year pace strikes a balance: it catches gradual corrosion and wear without imposing excessive costs or downtime from too-frequent testing, while still reducing the risk of undetected leaks between inspections. If testing were done more often, costs and downtime would rise without a proportional safety gain; if done much less often, leaks could go undetected for too long. The presence of the fire department representative ensures the test is conducted correctly and the results are credible for safety and regulatory purposes.
