Should the suction hose lay on the bottom of the stock tank?
Correct Answer
C. No, the suction hose should be up off the bottom of the stock tank about 4" to avoid sucking up particles
Explanation
The correct answer is that the suction hose should be up off the bottom of the stock tank about 4" to avoid sucking up particles. This is because if the suction hose is placed on the bottom of the tank, it will likely pick up any particles or debris that have settled there. By keeping the hose elevated, it ensures that only clean water is being sucked up, which is important for various applications such as pumping water for irrigation or filtering water for drinking purposes.
