What is the most important factor affecting the useful life of service lines?

The most important factor affecting the useful life of service lines is the ability of the material to resist internal and external corrosion. Corrosion can significantly reduce the structural integrity and lifespan of service lines, which are typically made from materials like metal or plastic. When a service line is subjected to corrosive conditions—whether from the water itself, environmental factors, or other external sources—the material can deteriorate over time, leading to leaks, failures, or contamination of the water supply.

While factors such as water supply abundance, pump type, and service line diameter may influence the operational efficiency or flow capacity, they do not directly impact the durability of the materials used in the construction of the lines. Understanding how different materials stand up to corrosion is critical in ensuring the longevity and reliability of water service infrastructure. This is why emphasis is placed on selecting and maintaining materials that provide strong corrosion resistance, as it is a key determinant in the overall longevity and safety of service lines.
