By identifying and addressing the source of manganese, you can reduce the risk of water contamination and protect your health.

Oxidation of Filter Materials

Corrosion of your filter's metal components can trigger an oxidation reaction, causing the filter to turn red as iron oxide and other metal oxides form and accumulate on its surface. This reaction occurs when the filter's materials, such as steel or aluminum, come into contact with oxygen, leading to material corrosion.

As a result, you may notice:

  • Rust or reddish-brown residue on the filter's surface
  • Discoloration of the filtered water
  • Decreased water flow or pressure
  • Unpleasant taste or odor
  • Filter replacement more frequently than expected

The oxidation reaction is a chemical reaction that occurs naturally when the filter's materials react with oxygen. However, it can be accelerated by factors such as high water pressure, temperature fluctuations, or exposure to air.

Understanding the oxidation process can help you take proactive measures to prevent material corrosion and maintain the effectiveness of your water filter.

Red Sediment From Well Water

If you're using a well water source, you may be introducing red sediment into your water filter, which can also cause it to turn red. This sediment can come from the natural iron and manganese present in your well water. When these minerals oxidize, they form red or brown particles that can accumulate in your filter, causing it to appear red.

To prevent this, it's essential to perform regular Well Maintenance. This includes inspecting your well casing, checking for signs of corrosion, and ensuring your well cap is secure.

Additionally, consider conducting regular Water Testing to identify any changes in your water's chemistry. This will help you stay on top of any potential issues before they affect your filter.

Filter Clogged With Red Clay

As you inspect your water filter, you may notice that it's turned red due to a buildup of red clay particles, which can clog the filter's pores and greatly diminish its effectiveness. This red clay buildup can be a common issue, especially if you live in areas where the water source contains high levels of iron oxide.

To prevent and address this issue, it's crucial to prioritize filter maintenance. Here are some tips to help you:

  • Regularly clean and flush your filter to remove accumulated red clay particles
  • Check your filter's specifications to make sure it's designed to handle high levels of iron oxide
  • Consider using a pre-filter or sediment filter to reduce the amount of red clay entering your main filter
  • Replace your filter cartridges regularly to prevent clogging
  • Monitor your water pressure and flow rate to identify any signs of filter clogging
