What is a common side effect of exceeding the upper limit of pH in water?

Exceeding the upper limit of pH in water can lead to several issues, one of the most significant being the corrosion of pipes. When the pH levels rise above the ideal range, typically above 8.5, the water can become more alkaline. Alkaline water can cause scaling and deposits to form on the inside of pipes, which can lead to increased roughness of the pipe surfaces. Over time, this can result in corrosion, particularly in metal pipes, as the balance of minerals and chemicals in the water changes. This corrosion not only affects the integrity and lifespan of the pipes but can also lead to the release of metals into the water supply, potentially creating health risks. Understanding the relationship between pH levels and pipe maintenance is crucial for ensuring the longevity of water distribution systems and the safety of drinking water.
