• B. 18 inches
• C. 24 inches
• D. 30 inches

Answer: (B)

The minimum required clearance in front of a cleanout for a 6-inch drainage pipe is 18 inches. This clearance is crucial for ensuring that there is sufficient space for maintenance and inspection activities. Cleanouts are access points in the plumbing system that allow for the removal of blockages and facilitate inspection of the drainage system.

The 18-inch requirement allows for adequate space to maneuver tools and perform necessary work, ensuring that inspectors and plumbers can effectively address any issues that arise without obstruction. This clearance helps to maintain safety and efficiency during plumbing inspections and repairs, making it an important aspect of plumbing code compliance.

Maintaining this minimum distance is part of the best practices to promote functionality and accessibility in residential plumbing systems.
