What should be ensured when inspecting a freshwater system?

When inspecting a freshwater system, ensuring that it functions properly on both pump and city water hookup is crucial because it guarantees the system's versatility and reliability. A well-functioning freshwater system should be able to draw water effectively from both sources, depending on the circumstances.

For instance, the ability to utilize city water means that users can connect to municipal supplies when available, providing a constant flow without reliance on the onboard freshwater tank. Meanwhile, the pump functionality ensures that when city water is not available, the system can still operate independently, drawing from stored freshwater.

This capability is essential for maintaining an adequate and reliable water supply during varying conditions, such as when traveling or when municipal water supply becomes unavailable. A system that can effectively switch between these two sources demonstrates a robust design and ensures that users can maintain access to water as needed, thus enhancing overall convenience and usability.

In contrast, while the other aspects such as not having visible leaks, maintaining a constant temperature, or using bottled water may be important for specific scenarios or preferences, they do not directly pertain to the primary operational capabilities of a freshwater system in the context of its overall function.
