The most likely reason you have excessive iron in your water is due to corrosion within your plumbing system. This corrosion often occurs when the water's pH is too low (acidic).
Here's a breakdown:
-
Corrosion of Plumbing: Iron and steel pipes, along with other plumbing components, are susceptible to corrosion, especially when water acidity (pH) is below 6.5. This corrosion releases iron into your water supply.
-
Source: While iron can naturally occur in groundwater, the primary culprit for high iron levels in residential water is often the internal plumbing.
-
pH Levels: Water's pH level is a measure of its acidity or alkalinity. A pH of 7 is neutral; below 7 is acidic, and above 7 is alkaline. Acidic water corrodes metal pipes more readily.
Solutions & Considerations:
-
Water Testing: The first step is to test your water to confirm the presence and concentration of iron, as well as to determine the pH level. This will help you identify the source and extent of the problem. You can typically find water testing kits at hardware stores or online, or hire a professional water testing service.
-
pH Neutralization: If your water is acidic (pH below 6.5), a neutralizing filter can be installed to raise the pH to a less corrosive level. These filters often contain calcium carbonate, which slowly dissolves and increases the pH.
-
Iron Removal Filters: There are several types of filters designed to remove iron from water, including oxidizing filters, iron exchange filters, and aeration systems. The best choice depends on the type and concentration of iron in your water.
-
Plumbing Replacement: In severe cases, if the corrosion is extensive, you might consider replacing old iron or steel pipes with copper or PEX (cross-linked polyethylene) piping, which are more resistant to corrosion.
-
Professional Consultation: It is advisable to consult with a qualified plumber or water treatment specialist to assess your specific situation and recommend the most appropriate solution.
By addressing the underlying cause, such as acidic water, and implementing appropriate filtration or plumbing upgrades, you can significantly reduce the iron content in your water and improve its quality.
