What happens to the duty pump at 10% tank level?

When the tank level reaches 10%, the duty pump is designed to turn off. This level indicates that the tank is getting too low, and the pump is usually programmed to shut down to prevent running dry, which could lead to pump damage or failure. The operational design typically includes safeguards against draining the tank completely to protect the equipment and maintain system integrity.

In contrast, at levels above the threshold, the pump would operate to maintain the necessary fluid level in the system. Option choices involving activation or continuous operation at such a low level would not align with standard operational protocols meant to preserve the equipment and ensure safety in the system.
