For piping over four inches in nominal diameter, how far apart should cleanouts not exceed?

50 feet
75 feet
100 feet
125 feet

The correct answer is: 100 feet

The appropriate maximum distance between cleanouts for piping that exceeds four inches in nominal diameter is 100 feet. This standard is established to ensure that blockages can be effectively addressed and maintenance can be carried out efficiently. Having cleanouts spaced at this interval allows for better accessibility when cleaning or clearing pipes, thus promoting proper drainage and minimizing potential plumbing issues over time. If cleanouts were placed further apart, accessing a blockage in the pipe would become more difficult and may create additional complications in maintenance procedures. Choosing this distance supports both the functionality and longevity of plumbing systems in larger diameter pipes, adhering to industry best practices for efficient waste removal and system upkeep.
