What is the purpose of a cleanout in plumbing systems?

The purpose of a cleanout in plumbing systems is to provide access for maintenance and remediation of blockages within the drainage systems. Cleanouts are strategically installed at various points in the plumbing system to allow a plumber to easily access pipes for inspection, cleaning, and clearing of clogs that may have developed over time. This accessibility is crucial in maintaining the efficiency and functionality of the plumbing system, ensuring that waste water can flow freely without interruptions.

While systems for drainage, connections, and prevention of backflow are integral to plumbing, none serve the specific purpose of allowing direct access to remove obstructions as a cleanout does. The cleanouts themselves are typically equipped with removable caps or plugs that facilitate this access, making them an essential component for effective plumbing maintenance.
