What is the primary function of potable water pumps onboard?

The primary function of potable water pumps onboard is to provide ship system pressure at 80-100 psi. This pressure is necessary to ensure that potable water is available for various uses throughout the ship, including drinking, cooking, and sanitation. Maintaining this pressure is crucial for the efficient operation of the ship's water distribution system, ensuring that water can reach all necessary locations without issue.

The correct function aligns with the needs of crew members for a reliable supply of safe drinking water and supports overall hygiene and daily operations onboard the vessel. This consistent pressure is essential not only in terms of functionality but also for safety, as each part of the system relies on adequate pressure to effectively deliver potable water.
