What is the main purpose of a plumbing cleanout?

The main purpose of a plumbing cleanout is to facilitate easy access to blocked pipes. Cleanouts are strategically placed access points in a plumbing system that allow plumbers to quickly reach clogged areas without having to dismantle any existing pipework. This access is critical for clearing blockages, performing maintenance, or conducting inspections of the plumbing system.

Having cleanouts installed at critical points in the drainage system makes it much easier to remove obstructions, whether they are caused by debris, grease buildup, or tree root infiltration. Their design typically consists of a removable cap or cover, which can be opened to insert a snake or other clearing tools to resolve any issues within the pipeline.

Although other choices might be relevant in different contexts—like pressure testing or maintaining water quality—these do not directly relate to the primary function and utility of cleanouts in plumbing systems. Cleanouts are specifically designed to address obstructions and blockages, making them an essential aspect of routine plumbing upkeep and maintenance.
