What is one requirement for a pumper that is designated as a fill site pumper?

A fill site pumper must be equipped with hard suction hose to effectively draw water from static sources such as ponds, lakes, or tanks. Hard suction hose is a rigid, reinforced hose that provides the necessary structural integrity to withstand the negative pressure created during the suction process. This capability is essential in ensuring that the pumper can successfully achieve the water supply needed for firefighting efforts.

The other options are not requirements for a fill site pumper. While having a certain flow rate or capacity is important for many pumpers, it is not a specific regulatory requirement for those designated just for fill sites. Similarly, features like automatic shut-off valves may enhance safety or efficiency, but they aren't universally mandated for fill site pumpers. The distance from the water source is also not a formal requirement; rather, it may be considered in operational planning but does not pertain to the essential functionality of the pumper itself.
