In plumbing, what is the purpose of a cleanout?

The purpose of a cleanout in plumbing is to provide access points in the drainage system to facilitate the removal of blockages or clogs. Cleanouts are essential components that allow plumbers to insert tools and equipment for snaking out obstructions, ensuring that the plumbing system remains functional and efficient. By allowing direct access to the interior of the pipes, cleanouts enable thorough inspections and cleanings without the need to dismantle extensive sections of the plumbing. This can prevent costly repairs and prolong the lifespan of the plumbing system.

Other options do not accurately reflect the primary function of a cleanout. For instance, while connecting different pipe sizes is an essential aspect of plumbing installations, cleanouts themselves are not designed for this purpose. Sealing off plumbing systems is typically achieved through the use of specific fittings and plugs, not cleanouts. Additionally, cleanouts do not serve a role in reducing water pressure, which is managed by various fixtures and devices within the plumbing system.
