The distance between cleanouts on horizontal waste lines larger than 2 inches shall not exceed _____________.

In the context of the Omaha Plumbing Code, the requirement regarding the distance between cleanouts on horizontal waste lines larger than 2 inches being no more than 100 feet is rooted in ensuring effective maintenance and accessibility for sewer line cleaning and inspections. This provision helps to prevent the build-up of debris and blockages, facilitating easier access for plumbers and technicians to maintain the plumbing system.

When cleanouts are placed too far apart, it becomes challenging to perform routine maintenance or respond to clogs, which can lead to more severe plumbing issues and increased costs for homeowners. The 100-foot limit strikes a balance between practical accessibility and minimizing unnecessary installation of additional cleanouts, reflecting a standardized approach to plumbing practices that prioritizes both functionality and safety.

In contrast, the other distances presented do not align with the established standard. For instance, a distance of 50 feet would place too many constraints, while 125 feet and 80 feet exceed what is deemed manageable for effective maintenance in residential or commercial settings. Thus, 100 feet is the recognized limit that adheres to best practices regarding waste line maintenance.
