    A. Depress air valve
    Explanation
    To determine if the dual pump stations accumulator has become waterlogged after long pump runs, you need to depress the air valve. By doing so, you can release any excess air that may have accumulated in the system. If water comes out instead of air, it indicates that the accumulator has become waterlogged. This can cause issues with the pump's performance and may require further inspection or maintenance.
