The correct answer is 42 inches because this is the standard height for standpipes above the trap weir, ensuring proper drainage and preventing siphoning or backflow issues. Standpipes are designed to facilitate the efficient flow of wastewater while maintaining enough height to prevent any obstruction or other issues that could arise from inadequate drainage. Allowing a maximum height of 42 inches helps ensure that the system functions effectively, adhering to plumbing codes and regulations that govern these installations. Such standards are critical for minimizing the risk of clogs and ensuring the reliability of the plumbing system overall.
