Why is it essential to use a non-collapsible hose with the P-100?

Using a non-collapsible hose with the P-100 is crucial to ensure consistent water flow. Non-collapsible hoses maintain their shape and structure even under pressure, allowing for a steady and reliable delivery of water. This characteristic is particularly important in firefighting situations and other emergency scenarios where a stable flow is necessary to effectively combat a fire or address a flooding issue. A consistent water flow aids in maintaining pressure and maximizing the efficiency of the pump, which is essential for successfully managing emergency conditions.

The other options may touch on practical considerations but do not directly address the operational efficacy of the P-100 in critical situations. The focus on a reliable and uninterrupted water supply highlights the importance of hose integrity during use.
