Corrosion is a natural process that gradually breaks down metal due to environmental factors such as chemical or electrochemical reactions. However, over time, even the sturdiest pipes, including copper that are designed to last over 50 years, can succumb to corrosion. For both homeowners and businesses, understanding what causes corrosion and how to spot the signs can help prevent costly plumbing issues down the line.

What you need to know about pipe corrosion

Signs Your Pipes May Be Corroding

Pipe corrosion doesn’t always make itself obvious immediately, but there are four telltale signs that something is wrong; spotting these signs early can help save you from major plumbing repairs and water damage in the future.

  1. Lower water pressure: Corrosion narrows the inside of pipes, restricting water flow and resulting in lower water pressure.
  2. Higher water bills: Pipe corrosion often results in hidden leaks that increase water consumption, leading to unexpectedly high water bills and unnecessary waste over time.
  3. Cloudy or discoloured water: Rust, sediment, or mineral deposits caused by corroding pipes can significantly impact water clarity, making it appear murky or tinted.
  4. Odd taste or smell: Corroding pipes can release metal particles or other substances into your water, leading to a metallic taste or an unpleasant, lingering odour.

Causes of Pipe Corrosion

Understanding what leads to corroded pipes is the first step in protecting your plumbing system. Here are the most common culprits:

  •       Hard Water
    Water with high levels of calcium and magnesium is often called “hard water”. While not harmful to health, the minerals in hard water can build up inside pipes and accelerate corrosion, especially in areas where water is already mineral-rich.
  •       Acidic Water
    Water with a pH level below 7 is considered acidic and can dissolve metal pipes from the inside out. This is particularly common in older systems or homes that rely on well water without proper filtration.
  •       High Oxygen Levels
    Oxygen in water reacts with the metal in pipes, leading to rust and accelerating corrosion over time. This issue becomes more significant in water systems where air frequently enters, increasing the oxygen content and intensifying the reaction.
  •       Chemical Drain Cleaners
    While convenient, many chemical drain cleaners contain harsh ingredients that can eat away at the inside of pipes over time, leading to weak spots and eventual leaks.
  •       Dirt and Bacteria
    Sediments and microorganisms can collect inside pipes, reacting with the metal and leading to localised corrosion. This is often an issue in systems that aren’t regularly flushed or maintained.
  •       Stress on Metals
    Excessive pressure or physical strain on metal pipes, especially steel, can cause them to crack. Once cracks form, corrosion quickly follows, compromising the integrity of the entire system.
  •       High Velocity Water
    Water moving too quickly through pipes can cause erosion corrosion. The rapid flow wears away the protective layer inside the pipe, exposing the metal and leaving it vulnerable to damage.Top Causes of Sewer Overflows and how to prevent them

Corrosion Is Preventable

Pipe corrosion can be a challenge, but it’s far from inevitable. Regular maintenance, water testing, and modern, corrosion-resistant materials significantly reduce the risk of corrosion.
