Question 429General Subjects - Assistant Engineer

The correct answer is D) item "H" being fouled or plugged. If water continues to flow excessively from the device shown in the illustration, the problem is most likely due to item "H" being fouled or plugged. The illustration appears to depict a water pressure relief or drain valve, and if this valve is blocked or obstructed, it would prevent the system from properly regulating the water flow, leading to excessive discharge. The other answer choices are incorrect because they do not directly address the root cause of the excessive water flow. "E" being stuck would not necessarily cause excessive flow, a hole in "B" or "C" would result in leakage rather than excessive flow, and fouling or plugging of other components is less likely to be the primary issue.
