During the daily inspection of the pump primer, what is a primary component to check?

Checking the primer oil reservoir level is essential during the daily inspection of the pump primer because it directly affects the primer's functionality. The primer is responsible for creating a vacuum to pull water into the pump system, and it operates effectively only when it has an adequate supply of primer oil. If the oil level is too low, the primer may not function correctly, leading to issues with pump priming and overall performance. Ensuring that the oil reservoir is filled to the appropriate level also helps maintain the longevity and reliability of the system, preventing potential breakdowns during operation. Other components, while important, do not have the same immediate impact on the primer's ability to function properly during a pump operation.
