The purpose of a cleanout in plumbing systems is to provide access for clearing blockages in the drainage piping. Cleanouts are strategically installed at certain points in a plumbing system, typically where angles in the piping occur or at key intervals along the drainage line. This accessibility allows plumbers to effectively remove clogs or obstructions without having to dismantle large sections of the plumbing. By allowing for easy access, cleanouts facilitate routine maintenance and emergency repairs, ensuring that the drainage system functions properly and efficiently.

The focus on cleaning out blockages underscores the importance of maintaining a healthy plumbing system to prevent backups and related issues, thereby ensuring the integrity and functionality of the system over time.
