Which of the following materials is typically used for water service lines?

• A. PVC
• B. Steel
• C. Copper
• D. Lead

Answer: (C)

The use of copper for water service lines is well-established due to its numerous advantages. Copper offers excellent durability and corrosion resistance, making it suitable for carrying potable water. It also has antimicrobial properties, which help in reducing the growth of bacteria within the pipes. Furthermore, copper can handle a wide range of temperatures and pressures, making it versatile for various plumbing applications. Its flexibility and ease of installation are additional benefits, allowing for better adaptability in different plumbing configurations. Other materials such as PVC are not typically used for underground water service lines due to issues related to temperature sensitivity and potential chemical leaching under certain conditions. Steel, while strong, is prone to rust and corrosion when exposed to water, which can lead to leaks and diminished water quality. Lead, known for its toxicity, is avoided in modern plumbing due to health risks associated with lead exposure, particularly in drinking water. As a result, copper remains the preferred choice for water service lines.
