Question 1378 Deck General

The correct answer is B) loss of suction. When stripping a tank, excessive air in the suction line can cause a loss of suction. This is because the air in the line reduces the density of the fluid being pumped, which decreases the pump's ability to create a strong enough vacuum to draw the fluid from the tank. As a result, the pump will lose its ability to suck the fluid from the tank, leading to a loss of suction. The other options are incorrect because: A) an over pressurized line is not a direct consequence of excessive air in the suction line, C) an increase in suction is the opposite of what occurs, and D) back pressure is not the primary issue caused by air in the suction line.
