What We Look For During a Sewer Scope Inspection

A sewer line can look perfectly fine from the surface while major problems develop underground. That’s why a professional sewer scope inspection is one of the most valuable inspections a homebuyer, homeowner, Realtor, or investor can order.

At The Sewer Inspection Company, we conduct a comprehensive video inspection of the sewer line to identify both current defects and potential future concerns. Our goal is to provide clear video evidence and professional observations so you understand exactly what condition the sewer system is in before making important decisions.

Why Sewer Scope Inspections Matter

Most sewer lines are buried underground and cannot be evaluated during a normal property walkthrough. Even if toilets flush and sinks drain properly, hidden defects may still exist inside the sewer system.

Over the years, I have inspected homes throughout Plano, Dallas, Frisco, Allen, McKinney, Richardson, and North Dallas where everything appeared normal inside the home, yet the sewer camera revealed significant defects underground.

A sewer scope inspection provides visual evidence of the pipe’s condition so buyers can make informed decisions before closing.

What We Look For During a Sewer Scope Inspection

1. Blockages and Clogs

Debris, grease buildup, wipes, paper products, toys, construction materials, and foreign objects can restrict water flow and eventually cause backups.

During the inspection we evaluate whether the sewer line has existing blockages or conditions that may contribute to future clogs.

2. Root Intrusion

Tree roots are one of the most common sewer defects found throughout North Dallas and Collin County.

Roots enter through joints, cracks, and pipe separations seeking moisture. Once inside the pipe, they continue growing and can eventually restrict or completely block wastewater flow.

We document:

  • Minor root intrusion
  • Moderate root intrusion
  • Heavy root masses
  • Complete root blockages

3. Bellied Sewer Lines

A sewer belly occurs when a section of pipe settles lower than intended.

This low area collects water and waste instead of allowing proper drainage.

Standing water can increase the likelihood of recurring drain problems and may contribute to future sewer failures.

4. Standing Water

Standing water often indicates settlement, poor slope, or a bellied sewer line.

Although some standing water conditions may remain serviceable for years, others may indicate larger structural concerns that require monitoring or repair.

5. Broken Sewer Pipes

Cracked, fractured, collapsed, or separated sewer pipes can allow wastewater leakage, soil intrusion, and root growth.

We carefully inspect for structural defects that may impact the long-term performance of the sewer system.

6. Offset Pipe Joints

Offset joints occur when two pipe sections no longer align correctly.

This condition is commonly caused by soil movement, settlement, foundation movement, or aging infrastructure.

Offsets can create flow restrictions and increase the likelihood of future blockages.

7. Cast Iron Pipe Deterioration

Many older homes throughout Dallas and Plano still utilize cast iron drain systems.

Over time cast iron pipes may develop:

  • Scaling
  • Corrosion
  • Channel Rot
  • Wall Loss
  • Structural Deterioration

Our inspections help determine the current condition of aging cast iron systems.

8. Pipe Separations

Pipe separations occur when sections of pipe pull apart or disconnect.

These openings can allow root intrusion, soil intrusion, and wastewater leakage into surrounding soils.

9. Construction Debris

New construction and remodeled homes are not immune to sewer problems.

We frequently discover:

  • Grout
  • Mortar
  • Concrete
  • Drywall debris
  • Building materials
  • Plastic construction waste

inside sewer systems.

10. Improper Repairs

Not all previous repairs are completed correctly.

We inspect for:

  • Poor pipe connections
  • Incorrect fittings
  • Improper transitions
  • Incomplete repairs
  • Questionable workmanship
