What is the maximum allowed distance from the fixture outlet to the trap weir?

A. 12 inches
B. 18 inches
C. 24 inches
D. 36 inches

The correct answer is: C. 24 inches

The maximum allowed distance from the fixture outlet to the trap weir is indeed 24 inches. This requirement is established in plumbing codes to ensure proper drainage and prevent issues like siphoning or blockage. When the distance exceeds 24 inches, it increases the likelihood that waste may not flow properly through the piping, leading to potential clogs and inefficient drainage. By adhering to this maximum distance, plumbers help maintain an effective drainage system that functions as intended, ensuring sanitary conditions in plumbing installations.
