A storm sewer inside a building shall extend to a point how many feet outside a building?

In plumbing code regulations, particularly concerning storm sewers, the requirement for extending a storm sewer to a specific distance outside a building is essential for ensuring proper drainage and preventing water accumulation near the foundation. Extending the storm sewer 2 feet outside the building is standardized to allow ample drainage without risking the potential for backflow or water infiltrating the structure.

This distance ensures that the effluent is properly directed away from the building's foundation and into a suitable drainage area, minimizing the risk of water damage and other related issues. Moreover, local building codes may have specific criteria that often align with this standard to maintain consistency across plumbing installations. In many jurisdictions, a 2-foot extension is considered effective in directing water away properly, making it a practical requirement in plumbing installation practices.
