What is the function of a sewer cleanout?

A sewer cleanout serves as a critical access point within the sewer system, primarily designed to facilitate the removal of blockages or debris. When a blockage occurs, it can lead to sewage backing up into residential or commercial spaces, potentially causing significant damage and health hazards. The cleanout allows plumbers to easily reach and clear obstructions without having to excavate or dismantle extensive sections of the sewer line.

While the other functions are relevant in plumbing systems, they do not capture the primary role of a sewer cleanout. Routine inspections can be conducted through various access points, and while reducing odors and improving water flow are important aspects of sanitation, they are not the main purpose of the cleanout itself. The design and placement of cleanouts in a sewer system focus on maintaining flow and ensuring that any buildup can be efficiently addressed, making ease of access to remove blockages their most significant function.
