For validating foam system integrity through a discharge test, how frequently should the test be conducted?

Explanation:
Testing the discharge of a foam system to validate its integrity should be done annually. This discharge test confirms the entire discharge path—pump performance, piping, valves, and nozzle or monitor—to ensure foam concentrate can be delivered at the correct flow and proportion. Regular annual testing aligns with maintenance standards and OEM guidelines, catching wear, leaks, or blockages before a real emergency. More frequent checks focus on general readiness and component condition, while less frequent (biennial) testing risks undetected degradation that could compromise performance when needed. If any repairs or changes are made to the foam system, a discharge test should be conducted after the work to re-verify integrity.
