A cleanout serves an essential function in a piping system by allowing for access to the drainage network, facilitating cleaning and maintenance. Over time, debris, buildup, or blockages can occur within the pipes, which can lead to disruptions in the flow or even backups. The presence of cleanouts enables a technician or plumber to insert tools or equipment into the system to remove these obstructions, ensuring the drainage remains effective. This access point is strategically located at various intervals along the drainage system to aid in thorough maintenance, significantly contributing to the overall functionality and longevity of the piping infrastructure.

The other options incorporate functions that are not roles of a cleanout. Preventing leaks in joints pertains to the integrity and sealing of the connections, improving water flow relates to the design and diameter of pipes, and acting as a valve for pressure control typically involves different types of devices designed for managing pressure, rather than a cleanout itself.
