How often must pressurized piping be tested along with monthly monitoring?

• A. 60 days
• B. 1 year
• C. 3 years
• D. 6 months

Answer: (B)

Monthly monitoring provides continuous leak detection, but it doesn’t replace a formal verification of the piping’s pressure boundary. The required approach is to perform an annual tightness test on the pressurized piping in addition to the monthly checks. This annual test confirms that the piping can hold pressure without leaks and catches issues that might develop between monthly inspections. Doing the test more frequently than yearly isn’t necessary given monthly monitoring, while waiting three years would leave a longer window for undetected leaks.
