What is the purpose of a cleanout in plumbing?

The purpose of a cleanout in plumbing is to provide access to drain lines for cleaning and maintenance. Cleanouts are strategically placed access points in a plumbing system that allow plumbers to reach and clear obstructions, such as clogs or buildup, without the need to dismantle extensive sections of pipe. This access is crucial for maintaining the efficiency and functionality of the drainage system.

By enabling easy entry to the pipes, cleanouts significantly reduce the labor and time required for routine maintenance and emergency repairs, ensuring that the plumbing system remains in good working order. This feature is essential for adequate plumbing performance, as it facilitates proper drainage and helps prevent more severe issues that could arise from blockages.
