In plumbing code, what is a cleanout needed for?

A cleanout is a crucial component in plumbing systems, primarily serving the purpose of allowing access to the drain line for inspection and cleaning. This access point facilitates maintenance by enabling plumbers to remove blockages, debris, or buildup within the piping system. Regular cleaning and inspection are important to ensure proper drainage and prevent issues such as backups or leaks, which can lead to more extensive damage if left unaddressed. Utilizing cleanouts effectively can significantly enhance the longevity and performance of the plumbing system, making them indispensable in both residential and commercial installations. Thus, the need for a cleanout in the context of inspecting and cleaning the drain line is foundational to maintaining a functional plumbing system.
