What is the maximum developed length of the indirect waste of any sanitary waste line?

  1. 2 feet

  2. 5 feet

  3. 8 feet

  4. 10 feet

The correct answer is: 5 feet

The correct answer is that the maximum developed length of the indirect waste of any sanitary waste line is 5 feet. This limit is established to ensure that indirect waste connections function properly and do not become a source of contamination or backflow problems. Keeping the length short helps maintain the integrity of the plumbing system by minimizing the likelihood of clogs or the accumulation of debris. Additionally, maintaining a shorter developed length helps facilitate proper drainage and ensures that any waste water is expelled effectively without the risk of stagnation. Other lengths exceed the recommended maximum, which could compromise the effectiveness of the indirect waste system and may lead to plumbing performance issues. Thus, the 5-foot limit is crucial for maintaining compliance with safety and health standards laid out in the Illinois Plumbing Code.
