What is Pipe Corrosion?

Pipe corrosion occurs when metal pipes deteriorate due to chemical reactions between the pipe material and the environment. Over time, this degradation weakens the pipes, causing leaks, blockages, and even complete pipe failure.

Corrosion is especially problematic in commercial buildings, where plumbing systems often handle higher water volumes and pressure, making them more susceptible to wear and tear.

Common Causes of Pipe Corrosion

Several factors contribute to the corrosion of pipes in commercial buildings:

  1. Water Quality
  2. Hard water, high mineral content, or water with high acidity (low pH) can accelerate corrosion.
  3. Chlorine and other chemicals in treated water can react with pipe materials, causing them to break down over time.
  4. Pipe Material
  5. Older pipes made of galvanized steel or cast iron are more prone to corrosion than modern materials like copper or PEX.
  6. Oxygen in Water
  7. Dissolved oxygen reacts with metal pipes, creating rust and weakening the pipe walls.
  8. High Water Pressure
  9. Excessive water pressure puts stress on pipes and can exacerbate corrosion.
  10. Improper Installation
  11. Incorrect pipe fittings, joints, or installation techniques can create weak points where corrosion is more likely to occur.
  12. Electrochemical Reactions
  13. When dissimilar metals are used in plumbing without proper insulation, galvanic corrosion occurs, leading to rapid pipe degradation.

Risks of Pipe Corrosion for Commercial Buildings

Failing to address pipe corrosion can have serious consequences for commercial properties:

  1. Water Leaks and Damage
    Corroded pipes are more likely to burst or leak, causing water damage to walls, ceilings, and floors.
  2. Increased Maintenance Costs
    Frequent repairs or pipe replacements due to corrosion can be expensive and disruptive.
  3. Health Risks
    Corroded pipes can introduce harmful metals, such as lead or copper, into the water supply, posing health risks to employees and customers.
  4. Reduced Operational Efficiency
    Plumbing issues caused by corrosion can disrupt business operations, affecting productivity and customer experience.
  5. Code Violations
    Corroded plumbing systems may fail to meet local building codes, leading to fines or required upgrades.

How to Prevent Pipe Corrosion

Preventing pipe corrosion requires proactive maintenance and smart plumbing solutions. Here’s what you can do:

  • Conduct Regular Plumbing Inspections

Routine inspections can identify early signs of corrosion and address issues before they escalate.

  • Install Water Treatment Systems

Water softeners and filtration systems can reduce minerals and chemicals that cause corrosion.

  • Replace Old Pipes

Upgrading outdated galvanized or cast-iron pipes to corrosion-resistant materials like copper, PVC, or PEX can prevent future problems.

  • Monitor Water Pressure

Installing pressure regulators can help maintain safe water pressure and reduce pipe stress.

  • Use Proper Materials and Insulation

Avoid mixing dissimilar metals in the plumbing system, or use dielectric unions to prevent galvanic corrosion.

  • Implement Cathodic Protection

For large commercial systems, cathodic protection methods can help reduce electrochemical corrosion in metal pipes.

Top Causes for Plumbing Failures in Restaurants and Retail Spaces

December 26, 2024
In restaurants and commercial spaces, plumbing systems are subject to heavy use and unique demands. From the constant flow of water in kitchens to the high-traffic use of restrooms, these systems face challenges that can lead to unexpected failures if not properly managed. Plumbing issues in commercial spaces can disrupt operations, damage property, and lead to costly repairs. Understanding the top causes of plumbing failures can help business owners take preventive measures to maintain their systems and minimize downtime. In this blog, we’ll explore the most common causes of plumbing problems in restaurants and commercial spaces and how to avoid them. 1. Grease Buildup in Drains Why It Happens: Restaurants generate significant amounts of grease and oil during food preparation. When these substances are poured down drains, they solidify over time, leading to clogs and blockages in the plumbing system. Consequences: Blocked drains can cause backups, slow drainage, and foul odors, disrupting kitchen operations. Prevention: Install grease traps and ensure they are cleaned regularly. Train staff to properly dispose of grease and oil in designated containers rather than pouring it down the sink. 2. High Water Usage and Strain on Fixtures Why It Happens: Restaurants and commercial spaces often have high water usage due to frequent handwashing, dishwashing, restroom use, and cleaning. Over time, this puts significant strain on fixtures and plumbing systems. Consequences: Fixtures can wear out faster, leading to leaks, reduced water pressure, or failure. Prevention: Use durable, commercial-grade fixtures designed for high-volume usage. Perform regular maintenance checks to identify and repair worn-out parts. 3. Clogged Toilets and Restroom Drains Why It Happens: In commercial restrooms, improper disposal of items like paper towels, feminine hygiene products, and wipes can lead to clogs in toilets and drains. Consequences: Restroom plumbing failures can result in unpleasant backups and disrupt business operations. Prevention: Post clear signage about what not to flush. Install heavy-duty toilets designed for commercial use. Schedule routine drain cleaning to prevent buildup. 4.
