What is the primary purpose of a cleanout plug in plumbing?

The primary purpose of a cleanout plug in plumbing is to provide service access to drainage systems. Cleanouts are strategic access points within plumbing systems that allow for the cleaning and maintenance of horizontal drain lines. By providing a way to remove blockages or to inspect the system, cleanouts are crucial for maintaining the proper operation of drainage systems.

Cleanout plugs are typically located at various intervals within a drainage system, particularly at bends or angles where clogs may be more likely to develop. This accessibility makes it easier for plumbers to effectively clear obstructions without needing to dismantle large sections of the plumbing system, which can be time-consuming and labor-intensive.

While maintaining airflow, preventing backflow, and securing connections are all important aspects of plumbing systems, they are not the primary function of cleanout plugs. Cleanout plugs specifically address the need for maintenance and serviceability within the drainage infrastructure, ensuring that systems remain effective and reducing the potential for more significant plumbing issues.
