What effect does corrosion have on service lines?

Increases water flow
Reduces useful life
Improves water quality
Enhances structural integrity

The correct answer is: Reduces useful life

Corrosion has a significant detrimental effect on service lines, primarily by reducing their useful life. Over time, the chemical reactions typically occurring in metal pipes lead to the degradation of the material, creating weak spots and increasing the likelihood of leaks or failures. As corrosion progresses, the structural integrity of the service line diminishes, ultimately shortening its lifespan and requiring more frequent repairs or replacements. This reduction in usefulness can also lead to increased maintenance costs and potential disruptions in water service. The other options do not accurately reflect the impact of corrosion. Instead of increasing water flow, corrosion can actually create blockages or reduce flow due to buildup of corrosion products. Corrosion does not improve water quality; in fact, it can leach harmful substances into the water, posing health risks. Additionally, corrosion decreases, rather than enhances, structural integrity, making the line more susceptible to breaks and failures.
