Your plumbing system is a network of hidden workhorses, faithfully carrying away waste and delivering fresh water throughout your home. But even the most reliable workers can face challenges. One such challenge is pipe corrosion, a silent threat that can cause significant damage if left unchecked.

Diving into the world of pipe corrosion to understand its causes, the havoc it can wreak on your plumbing system, and – most importantly – how to prevent it, is essential for homeowners. 



Understanding Pipe Corrosion: The Silent Destroyer

Corrosion is the deterioration of a material due to its interaction with its environment. In the case of pipes, it’s the breakdown of the metal or plastic due to exposure to water, chemicals, or electrical currents. Over time, this breakdown weakens the pipe, leading to leaks, bursts, and costly repairs.

Here are some of the most common culprits behind pipe corrosion:

  • Water Chemistry: Hard water, with its high mineral content, can cause minerals to build up and calcify on the metal pipes. This buildup can not only restrict water flow but also create weak points susceptible to corrosion. Conversely, acidic water with a low pH can eat away at the metallic structure of the pipes. The damage from corrosive sewer lines can be detrimental.
  • Electrochemical Reactions: When dissimilar metals come into contact in the presence of moisture, an electrical current can be created. This current accelerates corrosion, particularly on the less noble metal. For example, improper grounding of electrical appliances to a copper pipe can lead to rapid corrosion of the copper.
  • Stray Electrical Currents: Lightning strikes through utility pole grounding wires can introduce stray electrical currents into the plumbing system, accelerating corrosion.
  • Oxygen: Dissolved oxygen in water can also contribute to corrosion. As water travels through pipes, it picks up oxygen, which can react with the metal and cause it to deteriorate.
  • High Water Temperatures: Extremely hot water can weaken pipes and accelerate corrosion.
  • Sediment Buildup: Sand, dirt, and other debris accumulating in pipes can create an abrasive environment, wearing down the pipe walls and making them more susceptible to corrosion.
  • Improper Installation: Faulty plumbing practices, like using the wrong type of pipe or improper soldering, can create weak points where corrosion can take hold.
  • Chemical Drain Cleaners: Harsh chemical drain cleaners can damage pipes, making them more vulnerable to corrosion.


The Effects of Corroded Pipes: Nothing But Trouble

Corroded pipes unleash a cascade of problems for your home and health. The weakened pipe walls become susceptible to leaks and bursts, leading to significant water damage. This damage can be costly to repair and creates a breeding ground for mold growth, posing a health risk.

Reduced water flow is another consequence of corrosion. Buildup within the pipes restricts the flow of water, resulting in low water pressure. This not only makes everyday tasks like showering frustrating, but also impacts appliances that rely on water pressure to function efficiently.

Perhaps the most concerning effect is the potential contamination of your drinking water. As corrosion eats away at pipes, harmful metals and minerals can leach into your water supply. For example, copper pipe corrosion can cause blue staining in fixtures and potentially elevate copper levels in your water, leading to health issues.

In the most severe cases, extensive corrosion can render your entire plumbing system unusable. Replacing a complete plumbing system is a major undertaking, both in terms of cost and disruption to your home.


Signs of Pipe Corrosion

While corrosion often happens underground or behind walls, there are some signs of pipe corrosion that can alert you to a potential problem:

  • Discolored Water: Rusty or brown water can indicate corrosion of metal pipes. Blue staining suggests copper pipe corrosion.
  • Low Water Pressure: A noticeable decrease in water pressure throughout your home can be a sign of restricted flow due to corrosion buildup within the pipes.
  • Leaks and Drips: Visible leaks around pipes or fixtures are a clear indication of a problem. Even small, persistent drips can waste water and signal a potential for a larger burst in the future.
  • Unusual Noises: Gurgling, banging, or knocking sounds coming from your pipes can be caused by water rushing through narrowed passages due to corrosion.
  • Reduced Hot Water Capacity: If it takes longer than usual for hot water to reach your faucets, it could be due to restricted flow caused by corrosion in the hot water lines.
  • Cracked or Blistering Paint: If the paint near pipes is cracking or blistering, it could be due to moisture buildup caused by a leak behind the wall.


Preventing Pipe Corrosion: Knowledge is Power

Fortunately, there are steps you can take for preventing pipe corrosion and to protect your plumbing system:

  • Know Your Pipes: Understanding the type of pipes used in your home (copper, galvanized steel, PVC, etc.) is the first step. Different pipe materials have varying susceptibilities to corrosion.
  • Water Treatment: If you have hard water, consider installing a water softener to reduce mineral buildup and lessen the corrosive effects.
  • Maintain Water pH: In some cases, a pH adjustment system can be installed to neutralize acidic water and prevent corrosion.
  • Pipe Linings: Protective coatings applied to the inside of pipes can create a barrier against corrosion.
  • Regular Maintenance: Schedule regular inspections of your plumbing system by a qualified plumber. They can identify potential corrosion issues early on and recommend preventative measures.
  • Use Natural Drain Cleaning Methods: Avoid harsh chemical drain cleaners that can damage pipes. Opt for natural drain cleaning methods or call a professional pipe cleaner for stubborn clogs.
  • Minimize Hot Water Temperature: Reducing the temperature of your water heater can help to extend the lifespan of your pipes.
  • Proper Grounding: Ensure that all electrical appliances are properly grounded to prevent stray currents from damaging your plumbing system.


Taking Action: Time is of the Essence

If you suspect pipe corrosion in your home, don’t wait to take action. Here’s what to do:

  • Turn Off the Water Supply: The first step is to isolate the problem by turning off the main water supply valve to your home.
  • Call a Licensed Sewer and Drain Professional: A qualified technician can diagnose the extent of the corrosion and recommend the best course of action. This might involve repairing leaks, replacing corroded pipe sections, or relining existing pipes.
  • Consider Re-piping: In severe cases, complete replacement of the plumbing system might be necessary. A plumber can advise you on the most cost-effective and long-term solution for your situation.


Out of Sight, But Never Out of Mind

Pipe corrosion is a serious threat to your plumbing system, but it’s not inevitable. By understanding the causes and taking preventative measures, you can significantly reduce the risk of corrosion and protect your investment. Schedule regular inspections, maintain your water quality, and address any signs of trouble promptly. With proper care, your plumbing system can function reliably and safely for years to come.
