Where should cleanouts be provided in a plumbing system?

The provision of cleanouts in a plumbing system is essential for facilitating maintenance, cleaning, and inspection of the drainage system. Cleanouts are strategically placed to allow access to the interior of pipes for clearing blockages and performing other maintenance tasks.

The correct answer emphasizes that cleanouts should be located at points of exit from the building, where waste exits into the sewer system, as well as at changes in direction that exceed 45 degrees. This approach ensures that any potential blockages can be easily accessed and addressed. Changes in direction can create areas where debris and waste may accumulate, leading to clogs; therefore, having cleanouts at these critical junctures is vital for maintaining the functionality of the drainage system.

In addition to being positioned at points of exit, having cleanouts at angles greater than 45 degrees provides effective access to multiple points in the plumbing layout, facilitating easier maintenance across the entire system. This comprehensive access is key to preventing more serious plumbing issues that could arise from undetected blockages.

The importance of cleanouts cannot be understated, as they play a critical role in ensuring the system operates efficiently and effectively, allowing for straightforward maintenance when necessary. Proper placement of cleanouts ultimately contributes to the longevity and reliability of the plumbing system.
