For building sewers 8" and larger, how often must manholes be installed?

Every 1 inch
Every 1 foot
Every 2 inches
Every 2 feet

The correct answer is: Every 2 inches

The correct answer is that manholes must be installed every 2 feet for building sewers that are 8 inches in diameter and larger. This requirement is based on the need for maintenance and accessibility. Regular intervals allow for the proper inspection, cleaning, and maintenance of sewer systems. By providing openings at these spaced intervals, it ensures that any blockages, backflow issues, or structural problems can be readily addressed. It is important to follow specific local plumbing codes and regulations that dictate these requirements, prioritizing public health and safety by ensuring these systems are adequately maintained. Therefore, spacing manholes every 2 feet is a practical approach that balances accessibility with the operational needs of these larger sewer systems.
