This characteristic is crucial because plumbing systems can be used in diverse settings, including residential, commercial, and industrial locations, each with unique requirements and challenges. By accommodating various environments, plumbing codes aim to provide guidelines that ensure that installations are safe and functional regardless of where they are used. It ensures that plumbing systems can effectively manage different types of usage, water pressure, waste disposal needs, and environmental factors that may affect the integrity and performance of the plumbing system. This adaptability makes codes essential for protecting public health and safety in all plumbing applications.
