Where should additional cleanouts be located in a sewage system?

The placement of additional cleanouts in a sewage system is crucial for maintaining accessibility and functionality. The correct answer indicates that cleanouts should be situated within 5 feet of a 90° bend and every 100 feet of straight pipe. This placement is important because bends in sewer lines can create clogs, and having a cleanout nearby allows for easier access to address issues that may arise.

Moreover, while long runs of straight pipe can often function without requiring cleanouts at frequent intervals, establishing them every 100 feet facilitates access for routine maintenance and is typically a standard practice. The proximity to bends is specifically vital, as these areas are more prone to blockages due to the changes in flow direction.

In contrast, other choices suggest different distances that may not align with industry best practices for effective maintenance and clog prevention. Understanding the placement of cleanouts helps ensure that the system remains operable and accessible for any necessary repairs or inspections.
