What is the purpose of a cleanout in a drainage system?

The purpose of a cleanout in a drainage system is primarily to allow access for sanitation. Cleanouts are essential components strategically placed within the drainage system to enable maintenance and cleaning. They provide access points to the interior of the piping system, making it easier to remove blockages or perform inspections. This is particularly important because buildup can occur over time, leading to clogs and potential backups in the system. By providing access, cleanouts ensure the drainage system can be properly maintained, which is critical for the overall functionality and hygiene of the plumbing system.

While preventing odors, connecting fixtures, and facilitating drainage are important aspects of plumbing systems, they do not capture the primary function of cleanouts as access points for maintenance and sanitation purposes.
