Which condition prompts removing all water from a fire pump before storage?

• A. Freezing temperatures
• B. Heavy rain
• C. Very hot temperatures
• D. Windy conditions

Answer: (A)

Removing all water before storage is about protecting the pump from freezing. Water inside the pump and its connected lines can freeze in cold temperatures, and when it freezes it expands. This expansion can crack the pump housing, damage seals, bend impellers or valves, and cause leaks or failures when you start the unit again. Draining completely eliminates the liquid that could turn to ice, keeping the pump intact during storage in freezing conditions. The other conditions—heavy rain, very hot temperatures, or windy conditions—don’t create the same freezing risk, so they don’t necessitate draining for that reason. In those cases, other maintenance concerns might apply, but the primary reason to remove all water is to prevent damage from freezing.
