Sanitary sewer lines shall be labeled with what type of labels and letters?

Sanitary sewer lines must be clearly identified to prevent confusion and ensure proper handling during maintenance or construction. The requirement for a green label with white letters stands out because these color choices are often associated with specific meanings in plumbing and construction. Green typically indicates sanitary and drain lines, signaling their purpose and reducing the risk of accidental cross-connection with other types of piping systems. By using white letters on a green background, clarity is enhanced, ensuring that the labels are easily readable. This adherence to color-coded labeling helps promote safety and compliance with plumbing codes, which is essential in maintaining a functional plumbing system.
