What Causes Water Line Damage in Commercial Buildings?

Hurley Plumbing • July 3, 2025

Water line problems can be one of the most disruptive and costly issues a business owner faces. In a commercial building, even a small leak or break can lead to water damage, business interruptions, and expensive repairs if not addressed quickly. Understanding what causes water line damage in the first place is the first step toward preventing major headaches later.


Commercial water lines are under constant use, supplying water to restrooms, kitchens, sprinkler systems, and more. This high demand, combined with the unique stresses of larger buildings, makes them more susceptible to certain types of damage. Knowing the common causes of water line problems can help you spot early warning signs and call in professionals before a small issue becomes a big one.




The Most Common Causes of Damage

One of the leading causes of commercial water line damage is simply aging pipes. Over time, materials like steel and copper corrode, especially when exposed to minerals and chemicals in the water. This gradual wear and tear can weaken pipes until they eventually crack or burst. Another common factor is ground movement. Buildings settle and soil shifts, which can put stress on buried pipes, leading to breaks or leaks.


External forces are another issue. Heavy machinery on construction sites, nearby digging, or even traffic vibrations can damage water lines beneath parking lots or sidewalks. Temperature changes also play a role. During cold winters, water inside the pipes can freeze and expand, creating cracks. When temperatures warm up, those cracks can turn into leaks. Poor installation practices or low-quality materials can also lead to premature failure, even in newer buildings.


How to Tell if Your Water Line is Damaged


Spotting a damaged water line early can save you from costly repairs and extensive water damage. Some warning signs are obvious, while others are more subtle and easy to overlook. Paying attention to changes in your building’s plumbing and water supply can help you catch problems before they escalate.


Look out for these signs of water line trouble:


  • Unexplained wet spots in walls, ceilings, or floors

  • Puddles forming around the exterior of your building

  • Unusually high water bills without increased usage

  • Drop in water pressure throughout the building

  • Discolored or rusty-looking water from faucets

  • Sounds of running water when no fixtures are in use

If you notice any of these signs, it’s time to have your water line inspected by a professional plumber right away.


What to Do if You Suspect Damage


If you think your commercial water line might be damaged, the best thing you can do is act quickly. Ignoring the issue can lead to bigger problems like mold, structural damage, and even health hazards for employees and customers. Shut off the water supply to minimize any immediate damage and avoid using affected fixtures until the problem is assessed.
