On which port should screens be inspected for rocks or debris?

The intake ports of a fire apparatus are critical for ensuring the efficient operation of the pump. These ports are responsible for drawing water into the system from a supply source. Inspecting them for rocks or debris is essential, as any blockage can hinder the flow of water, potentially impacting the pump's performance and the apparatus's overall capability to deliver water during emergency situations.

Debris or obstructions at the intake can lead to cavitation, which occurs when the pump is unable to draw adequate water, leading to possible damage and reduced efficiency. Therefore, regular inspections of intake ports help maintain optimal performance and safety standards of the fire apparatus.
