What is a key component that should be checked during a monthly churn test?

The key component that should be checked during a monthly churn test is the water flow rate. This test is critical for ensuring that the fire protection system is capable of delivering the necessary amount of water in the event of an emergency. Monitoring the water flow rate helps verify that the system is functioning correctly and that there are no obstructions or leaks affecting performance. A consistent and adequate water flow rate is essential for the effective operation of the sprinklers.

While checking air pressure, submitting defect reports, and evaluating system piping integrity are also important aspects of system maintenance, they are not specifically the focus of a monthly churn test. The churn test primarily assesses the system's operational readiness through flow rate validation, making it a vital component of fire safety and prevention protocols.
