What is one key purpose of maintaining access to waste-line cleanouts in plumbing design?

Maintaining access to waste-line cleanouts in plumbing design is crucial primarily due to the need for ongoing maintenance. Cleanouts are designated access points that allow plumbers to clear blockages and perform necessary inspections within the plumbing system. This accessibility ensures that any clogs or issues within the waste line can be promptly addressed, preventing potential health hazards or extensive damage to the plumbing infrastructure.

When cleanouts are strategically placed and easily accessible, maintenance work can be carried out efficiently, reducing the time and labor involved. This proactive approach not only enhances the longevity and reliability of the plumbing system but also minimizes emergencies that could arise from undetected problems. Proper access to cleanouts ultimately supports the overall functionality and performance of the plumbing system in any building.
