What is the first step in correctly pumping from an internal tank?

• A. Activate the discharge valve
• B. Establish a suction line to the tank
• C. Fill the tank to maximum capacity
• D. Check the flow rate settings

Answer: (B)

Establishing a suction line to the tank is indeed the first step in correctly pumping from an internal tank. This step is crucial because the suction line creates the necessary pathway for the fluid to move from the tank into the pump system. Without a functional suction line, the pump cannot draw fluid effectively, making it impossible to begin the pumping process.

Once the suction line is in place, the operator can then proceed to perform other necessary actions such as activating the discharge valve, filling the tank to capacity, or checking flow rate settings. However, these steps depend on having a properly established suction line to ensure efficient and effective pumping operations.
