In the world of underground plumbing and utility infrastructure, what lies beneath can often be a mystery—until it’s too late. Leaks, blockages, cracks, and collapsed pipes are just the tip of the iceberg when it comes to what can go wrong underground. That’s where video pipe inspection becomes a vital tool. It’s a non-invasive, highly accurate method to visually inspect the interiors of pipelines, sewer systems, storm drains, and other underground conduits in real time.
At On The Mark Locators, we use cutting-edge camera systems to identify, diagnose, and report hidden issues inside pipes—without digging. This advanced technique provides fast diagnostics, saves time and money, and helps prevent catastrophic failures in both residential and commercial systems.
In this blog, we’ll explore the most common problems uncovered by video pipe inspections, from intrusive roots to major structural cracks, and how identifying these issues early can save thousands in repairs and downtime.
1. Tree Root Intrusion: Nature’s Silent Pipe Wrecker
Tree roots are one of the most frequent and damaging problems found during a video pipe inspection. Seeking moisture, roots naturally grow toward tiny leaks or condensation around sewer pipes, especially older clay, concrete, or cast iron lines. Once inside, they can expand rapidly and cause major blockages or even collapse sections of pipe.
How video inspection helps:
- Live footage shows exactly where the roots have entered.
- It reveals the extent of the invasion.
- It helps determine whether hydro jetting or pipe replacement is necessary.
Consequences if untreated:
- Backed-up sewage into the home or building.
- Complete pipe failure.
- Costly excavation and replacement.
Pro tip from On The Mark Locators:
Annual or bi-annual inspections for properties with mature trees can help you catch root intrusions early, long before they become expensive plumbing disasters.
2. Cracked or Fractured Pipes: Hidden Structural Damage
Cracks in underground pipes can occur due to soil movement, temperature fluctuations, ground settling, or corrosion. These small cracks often start as minor issues but can quickly grow into major leaks or even cause complete pipe failure.
Warning signs:
- Wet patches in your yard or driveway.
- Foul odors.
- A sudden drop in water pressure.
What video pipe inspection reveals:
- Size, location, and depth of the crack.
- Whether the pipe is at risk of collapsing.
- If the damage is localized or affecting an entire section.
Why it matters:
Cracked pipes can lead to contaminated water, soil erosion, or damage to nearby foundations and landscaping.
At On The Mark Locators, we provide detailed inspection footage and reporting so plumbing professionals can make informed repair decisions based on real, visual evidence.
3. Pipe Corrosion and Deterioration: Aging Infrastructure Under Stress
Many older buildings and municipal systems still rely on metal piping—such as cast iron or galvanized steel—which corrodes over time. Corrosion weakens the pipe structure, restricts flow, and can cause rust-colored water or leaks.
What video pipe inspections show:
- Scaling or pitting on the interior walls.
- Thinning or discolored sections of pipe.
- Areas prone to future failure.
Key insights:
Video footage helps determine if pipe relining or replacement is needed and whether the corrosion is chemical (from harsh waste materials) or natural (from age and oxidation).
4. Blockages and Buildups: From Grease to Foreign Objects
Grease, debris, hygiene products, and even construction waste can accumulate over time and create blockages. These slow down flow and cause backups, flooding, or pipe bursts. A video pipe inspection can locate the blockage and identify its material—making it easier to choose the right removal method.
Common culprits:
- Fats, oils, and grease (FOG)
- Food particles and paper towels
- Toys, jewelry, or other flushed items
- Construction debris
What the camera detects:
- Type and composition of the blockage.
- Its exact location and severity.
- Whether it’s a one-time event or a recurring problem.
At On The Mark Locators, we often work with contractors and homeowners to troubleshoot mystery blockages that have stumped traditional snaking methods. A camera tells the whole story—saving hours of guesswork.
5. Misaligned or Collapsed Pipes: When Gravity Stops Working
Ground shifting, poor installation, or heavy traffic overhead can lead to pipe misalignment or full-on collapse. When this happens, wastewater can’t flow properly and starts backing up.
Signs of this issue:
- Frequent backups with no clear cause.
- Gurgling drains.
- Persistent wet spots in soil or lawn.
How video inspection helps:
- It identifies bellies (sags in the line), offsets, and full collapses.
- Shows how much of the pipe is misaligned.
- Determines if trenchless repair methods like pipe bursting or lining are viable.
Why it’s serious:
Misaligned pipes can also cause wastewater to leak into the surrounding soil—posing serious environmental and health hazards. Video inspections help mitigate legal liability and environmental risk.
6. Poor Pipe Installation or Defective Materials: Built-In Problems
Sometimes, the biggest issues start at day one. Pipes that were improperly installed—wrong slope, incorrect joints, or use of substandard materials—can cause chronic drainage problems or premature failure.
What we see in the field:
- PVC pipes joined without proper fittings.
- Inadequate slope for drainage.
- Inconsistent pipe diameters.
- Materials that degrade too quickly (especially in older builds).
Benefits of inspection here:
- Identifies areas that violate building codes.
- Helps construction teams avoid repeating mistakes.
- Saves money by correcting errors before final buildout.
Whether it’s a commercial complex or a single-family home, On The Mark Locators has saved property owners thousands by uncovering these problems early—before drywall, driveways, or landscaping go in.
Conclusion
Whether you’re dealing with root intrusion, cracked pipes, corrosion, or unknown blockages, a video pipe inspection is one of the smartest investments you can make in your plumbing or sewer system. It’s fast, non-invasive, and gives you a detailed understanding of what’s really going on underground.
