For a cleanout, what is the minimum clearance required below the lowest inlet opening?

For a cleanout, maintaining the correct minimum clearance below the lowest inlet opening is crucial for proper drainage and access for maintenance. The established guideline specifies that there should be at least 6 inches of clearance. This distance allows for sufficient access for cleaning and maintenance equipment to function effectively, while also ensuring that any potential blockages can be easily addressed.

Adequate clearance is vital in preventing backflow issues and ensuring that the drainage system operates efficiently. Cleanouts are strategically placed in plumbing systems to allow for easy access to the interior of pipes for inspection and removal of clogs. Having less than the required 6 inches could hinder these activities, complicating maintenance efforts and impacting the plumbing system's overall performance.

This standard is designed to promote both efficiency in maintenance practices and the ongoing functionality of the plumbing system, highlighting the importance of adhering to proper specifications regarding cleanout installations.
