A straight run of building sewer will require cleanouts at intervals not to exceed _____ feet.

The requirement for cleanouts along a straight run of building sewer is crucial to maintaining the functionality and accessibility of the plumbing system. Cleanouts allow for easy access to the sewer line for inspection, cleaning, and maintenance purposes. The Uniform Plumbing Code stipulates that cleanouts should be installed at intervals not exceeding 100 feet in a straight run of building sewer. This distance ensures that blockages can be addressed within a reasonable range and minimizes the risk of extensive damage or costly repairs if a problem arises. By having cleanouts every 100 feet, it facilitates the flow of wastewater and enhances the overall reliability of the sewer system.
