The clearance required in front of a 2 inch clean out shall not be less than _____ inches.

The requirement for a 12-inch clearance in front of a 2-inch clean out is crucial for maintenance and accessibility. This specific clearance ensures that plumbers and maintenance personnel have sufficient room to perform necessary inspections, cleaning, and repairs without obstruction. Adequate space helps to prevent accidents, facilitate the use of tools, and allows for effective operation of the clean out itself, which is essential for maintaining the plumbing system.

The maximum clearance requirements are outlined in plumbing codes to ensure safety and efficiency. A smaller clearance may impede access, creating challenges when dealing with blockages or other plumbing issues. A 12-inch clearance provides a standard that enhances ease of access and promotes proper plumbing maintenance practices.
