Learn more about Sewer Camera Inspections
Technology has made it easier and more efficient to identify the reason behind plumbing issues while helping the professional determine the best solution.
When plumbing problems stubbornly persist, such as recurring clogs, slow drains, or mysterious backups, the solution often lies deeper than a surface-level fix. Hidden issues inside sewer lines and drain pipes are common, and diagnosing them without tearing into walls or digging up yards used to be guesswork. Today, sewer camera inspections have changed the game.
Also known as drain line inspections or video pipe inspections, sewer camera inspections allow plumbers to see the inside of pipes and sewer lines in real time. This technology provides the clarity needed to pinpoint problems quickly and accurately — saving time, money, and stress for homeowners and property managers alike.
In this guide, we’ll explain what sewer camera inspections are, how they work, why they matter, common problems they detect, when they’re recommended, and how to prepare for one.
What Is a Sewer Camera Inspection?
A sewer camera inspection is a diagnostic service in which a professional plumber uses a small, waterproof video camera attached to a flexible cable to inspect sewer lines and drain pipes. As the camera travels through the pipe, it transmits live footage to a monitor so the plumber can see blockages, damage, and other abnormalities.
Unlike traditional methods that rely on speculation or disruptive excavation, sewer camera inspections allow technicians to visually inspect the interior of pipes without digging or demolition. It’s a precise, non-invasive way to identify what’s happening beneath your home or business.
Why Sewer Camera Inspections Matter
Many plumbing problems can appear similar on the surface — slow drains, backups, or odors. But the underlying causes can vary widely. Without seeing inside the pipe itself, fixes may miss the real issue entirely.
Here’s why sewer camera inspections are so valuable:
• Accurate Diagnosis – Visual inspection eliminates guesswork.
• Time and Money Savings – Problems are identified quickly, reducing unnecessary labor.
• Targeted Repairs – Knowing the exact issue allows for precise solutions instead of broad fixes.
• Prevents Repeat Issues – Fixing only symptoms often leads to recurring service calls.
• Protects Property – No unnecessary digging or demolition when the issue can be located precisely.
For both residential and commercial properties, sewer camera inspections provide transparency and confidence, allowing plumbers to recommend the best solution based on what they actually see.
How Sewer Camera Inspections Work
The inspection process is straightforward and efficient:
1. Locate an Access Point
Technicians begin by finding a suitable entry point into the sewer or drain line. This is often a cleanout, floor drain, or another service port.
2. Insert the Camera
A waterproof camera mounted on a long, flexible cable is carefully fed into the pipe. The technician controls the camera’s movement and watches a live video feed.
3. Inspect the Pipe Interior
High-resolution video allows the technician to observe blockages, cracks, root intrusion, joint separations, corrosion, bellies (sags), and other issues. Some systems also measure distance, so the exact location of the issue can be mapped.
4. Diagnose and Recommend
After inspection, the plumber reviews what was found, explains the problem in clear terms, and recommends appropriate fixes. Many professionals also record footage for future reference or homeowner review.
Common Problems Detected by Sewer Camera Inspections
Sewer camera inspections are used to uncover many types of issues that are otherwise hidden from view. Common findings include:
Blockages and Clogs
Accumulated debris like grease, hair, soap scum, and foreign objects can collect inside pipes, slowing water flow. Recurring clogs often indicate deeper buildup in sewer lines.
Tree Root Intrusion
Tree roots naturally seek moisture and can penetrate small cracks or joints in sewer pipes. Once inside, roots grow and trap debris, leading to clogs and potential pipe damage.
Cracked or Broken Pipes
Age, shifting soil, freezing conditions, or external pressure can cause pipes to crack or break. Camera inspection clearly shows where and how severe the damage is.
Pipe Corrosion or Deterioration
Older plumbing materials can corrode over time, roughening interior surfaces and trapping debris. Camera inspections reveal early signs before full failure occurs.
Bellies and Sagging Pipes
Sections of pipe that have sunk or lost proper slope create low points where water and debris collect. These areas often become hotspots for recurring clogs.
Offset Joints and Misalignment
Improper installation or shifting soil can cause pipe joints to move out of alignment, restricting flow and creating points of buildup.
When to Schedule a Sewer Camera Inspection
A sewer camera inspection may be recommended in several situations, including:
Persistent or Recurring Clogs
If you've cleared a clog multiple times only to have the problem return, it’s a strong sign that the source is deep within the sewer line.
Multiple Slow Drains
When more than one drain slows down at the same time, the issue is often farther down the main line.
Backups After Heavy Rain
Water entering sewer lines during storms can reveal cracks or overwhelmed systems that need inspection.
Foul Odors
Persistent sewer smells in the yard, basement, or near drains often originate from sewer line issues.
Before Purchasing a Property
Home buyers frequently request sewer camera inspections as part of pre-purchase evaluations to avoid costly surprises later.
Prior to Major Landscaping or Construction
If you're planning major work near sewer lines, an inspection can prevent accidental damage and ensure lines are in good condition.
Residential vs. Commercial Inspections
Sewer camera inspections serve both residential and commercial properties, but commercial systems may require additional considerations. Commercial sewer lines tend to be larger, handle heavier usage, and often involve more complex routing. Inspections in commercial settings may incorporate more advanced equipment and follow additional safety protocols.
For homeowners, a typical inspection focuses on main sewer lines, branch lines from multiple fixtures, and identifying common blockages. Regardless of property type, the goal is the same: locate issues accurately and recommend appropriate solutions.
Benefits Beyond Problem Diagnosis
Sewer camera inspections not only help solve current problems, but they also:
• Provide Documentation – Recorded footage can document plumbing condition over time, useful for maintenance planning or sale disclosures.
• Guide Preventive Maintenance – Inspections help target areas that might fail in the future, allowing proactive fixes.
• Reduce Emergency Repairs – Early detection keeps small issues from turning into major failures that require urgent intervention.
• Save Money Long-Term – Accurate diagnosis prevents unnecessary excavation and reduces guesswork.
In short, sewer camera inspections are an investment in the health and longevity of your plumbing system.
Preparing for a Sewer Camera Inspection
Preparing for a sewer camera inspection is simple and helps ensure a smooth process:
Clear Access Points
Make sure cleanouts or exterior access points are accessible. Remove obstacles like landscaping, debris, or outdoor furniture.
Explain Recent Problems
Let your plumber know when the issue started, what symptoms you’ve seen, and any patterns you’ve noticed. This helps focus the inspection.
Secure Pets and Kids
Keep pets and children away from work areas for safety and efficiency.
Plan for Follow-Up
After the inspection, your plumber will recommend the best path forward. Be ready to discuss options, costs, and timing for any necessary repairs.
What Happens After the Inspection
Once the sewer camera inspection is complete and problems are identified, a licensed plumber will explain what was found and recommend solutions. Repairs might include:
• Hydro jetting to clear deep blockages
• Pipe repair or replacement
• Root removal and preventive barriers
• Bellied pipe correction or rerouting
• Structural rehabilitation with pipe lining
Professional plumbers can match solutions to the severity and type of issue, ensuring that repairs are effective and long-lasting.
Protect Your Plumbing with Regular Inspections
Sewer camera inspections shouldn’t be reserved only for emergencies. Many property owners choose regular inspections as part of routine plumbing maintenance. Especially in older homes, high-usage buildings, or properties with mature landscaping near sewer lines, periodic inspections help catch trouble early.
A proactive approach keeps plumbing flowing smoothly, prevents backups, and minimizes unexpected repair costs.
