What is a common indicator that a fire pump is experiencing issues during a response?

Fluctuating psi readings are a key indicator that a fire pump may be experiencing issues during a response. When a fire pump operates properly, it should maintain steady pressure readings that correspond with the system's demands. Fluctuations can suggest various problems, such as air leaks in the suction line, obstruction in the pump or discharge piping, or issues with the pump itself, such as wear or damage to internal components.

When the psi readings fluctuate, it may result in inconsistent water flow to the fire scene, impacting firefighting efforts. For fire personnel, identifying this issue early is crucial for addressing mechanical failures and ensuring that the pump operates efficiently to provide the necessary pressure and flow for firefighting operations.

Understanding this aspect of fire pump operation allows firefighters and engineers to troubleshoot effectively and maintain operational readiness during emergencies.
