All pumpers are rated from __.

Pumpers are rated from draft, which refers to the ability of a fire pump to draw water from a source that is below the pump's elevation, such as a body of water or a tank. This rating is crucial because it indicates the pump's capacity to operate effectively when not connected to a pressurized water supply, ensuring that firefighters can access water in various situations, including rural or remote environments where hydrants may not be available.

Understanding draft capability is essential for firefighters and emergency responders, as it affects the performance and efficiency of fire suppression efforts. The ability to draft water plays a key role in firefighting operations, especially when responding to incidents where conventional water sources are not accessible.

Other options, like front suction or side suction, refer to specific methods of connecting to water sources, but they do not encompass the broader operational rating that the term "draft" covers. "All ports running" implies utilizing multiple inlets of the pump but does not inherently address the core rating that influences overall performance in diverse scenarios.
