Sewer Inspection: Everything You Need to Know | Complete Guide by Octopusscan

A sewer inspection is one of the most effective ways to identify hidden drain and pipeline problems before they become costly repairs. Using a professional sewer inspection camera, plumbers, contractors, and property owners can visually inspect underground pipes without excavation.

In this complete guide, Octopusscan explains what sewer inspections are, how they work, when they are needed, and why modern sewer camera inspections are essential for residential and commercial properties.

What Is a Sewer Inspection?

A sewer inspection is a non-invasive process that uses a high-resolution sewer camera to examine the interior condition of sewer and drain lines. The camera is inserted into the pipe through a cleanout or access point and transmits real-time video to a monitor.

This inspection method allows professionals to diagnose problems accurately without digging or guesswork.

How Does a Sewer Inspection Work?

A typical sewer inspection follows these steps:

1. The camera is inserted into the sewer line

2. Live video footage reveals the internal pipe condition

3. Issues are identified and documented

4. A repair or maintenance plan is created based on findings

Many professional systems include 512Hz transmitters, allowing operators to locate the exact position and depth of problems underground.

Why Sewer Inspections Are Important

Sewer problems often develop slowly and remain hidden until major damage occurs. Regular sewer inspections help:

• Detect issues early

• Prevent emergency repairs

• Reduce excavation costs

• Extend the lifespan of sewer systems

• Provide clear documentation for property owners

Common Problems Found During Sewer Inspections

1. Blockages and Clogs

Grease, debris, sediment, and foreign objects commonly restrict pipe flow.

Sewer cameras can identify:

• Blockage location

• Severity

• Type of obstruction

2. Tree Root Intrusion

Roots enter pipes through cracks or joints and are a leading cause of recurring sewer backups.

Inspection benefits:

• Identifies root entry points

• Helps plan targeted root removal

3. Cracked, Broken, or Collapsed Pipes

Aging pipes, soil movement, and heavy loads can cause structural failure.

What cameras reveal:

• Hairline cracks

• Pipe deformation

• Partial or full collapse

4. Corrosion and Pipe Deterioration

Cast iron, clay, and concrete pipes degrade over time.

Inspection reveals:

• Rust buildup

• Surface erosion

• Material wear

5. Misaligned or Offset Joints

Improper installation or ground movement can shift pipe joints.

Why this matters:

• Restricts flow

• Increases clog risk

6. Pipe Bellies and Sagging Sections

Low spots in pipes allow water to collect, leading to recurring blockages.

Inspection advantage:

• Confirms slope problems

• Identifies exact sag locations

When Should You Get a Sewer Inspection?

Sewer inspections are recommended when:

• Purchasing a home or commercial property

• Experiencing frequent drain backups

• Noticing slow drainage or foul odors

• Maintaining older sewer systems

• After major plumbing repairs or renovations

Who Uses Sewer Inspection Cameras?

Sewer camera inspections are widely used by:

• Professional plumbers

• Drain cleaning companies

• Property inspectors

• Facility managers

• Municipal maintenance teams

Sewer Inspection for Home Buyers

A sewer inspection before buying a property can uncover hidden issues that standard home inspections often miss. Identifying problems early can help buyers negotiate repairs or avoid unexpected costs.
