What is a critical factor affecting the useful life of service lines?

Corrosion is a critical factor affecting the useful life of service lines because it directly impacts the integrity and strength of the material. Over time, corrosive elements, often found in the water itself or in the surrounding soil, can lead to the deterioration of metal pipes, resulting in leaks or total failure of the service line. The rate of corrosion can vary based on the type of material used in the service line (e.g., copper, iron, plastic), the quality of the water (e.g., pH, oxygen content), and environmental conditions (e.g., temperature and humidity).

While other factors, such as internal pressure and temperature fluctuations, can affect the operation of service lines, they often do not influence the degradation of materials to the same extent as corrosion. Material thickness can contribute to a service line's ability to withstand pressure but does not inherently protect against corrosion. Thus, the pervasive issue of corrosion ultimately plays a more substantial role in determining the longevity of service lines.
