Ever wonder what's going on inside your pipes? Sewer camera inspections provide a clear view of underground pipes in real time, helping to detect problems such as blockages, cracks, or root damage, without the need to damage our plumbing system. 

In the text article, we will start with the aspect of sewer camera inspection and fully understand the purpose, benefits, and process of using it. Let's read on.

What Is a Sewer Camera Inspection?

A sewer camera inspection is a diagnostic procedure that uses a waterproof, high-resolution camera to inspect the interior condition of sewer lines and other underground pipes. The camera is attached to a flexible rod or cable and inserted into a cleanout access point. 

As the camera is guided through the pipe, it transmits live video to a monitor above ground. This lets the operator see exactly what's happening inside the sewer line in real time. Some advanced systems even include a built-in 512 Hz locator that helps pinpoint the exact location and depth of the issue underground.

Why Sewer Camera Inspections Are Needed

Sewer camera inspections eliminate the guesswork and show the precise condition of the pipe. This is valuable for a range of scenarios:

1. Recurring drain clogs

If toilets, sinks, or tubs keep backing up despite clearing efforts, the problem may lie deeper in the sewer line. A camera inspection can reveal if there’s a blockage, broken pipe, or buildup causing the issue.

2. Suspected tree root intrusion

Roots can grow into sewer lines through tiny cracks or joints and cause severe damage. A camera can visually confirm root infiltration and guide targeted removal.

3. Sewer odor issues

Bad smells inside or outside the home can be due to a cracked pipe, a broken trap, or poor drainage. The camera can help locate the source of the odor.

4. Before home purchase

Many buyers request a sewer inspection as part of their due diligence. Replacing a main sewer line can cost thousands of dollars, and a camera inspection helps avoid nasty surprises after closing.

5. Post-repair verification

After sewer work is done, an inspection can confirm that the problem was fully resolved and that the pipe is in good condition.

How Does the Sewer Inspection Work？

The process of a sewer camera inspection is relatively straightforward, but it does require some technical skill to interpret the findings accurately.

1. Preparation and access: First, you—or the technician—will locate the nearest accessible cleanout, which is a capped pipe connected to your sewer line, and remove the cover. If there’s no cleanout available, access may be gained through a drain or a vent stack.

2. Camera insertion: Next, a camera mounted at the tip of a long, flexible cable is inserted into the sewer line. Depending on the equipment, you’ll feed the cable slowly through the pipe, either by hand or with a motorized reel.

3. Real-time monitoring: As the camera moves through your sewer line, it sends live video footage to a monitor. You can watch for signs of damage, blockages, or buildup. Some systems also let you record the footage for future reference or for sharing with a contractor.

4. Locating the problem: If the camera detects an issue—such as a crack, sag, or obstruction—you can use a locator tool above ground to find the exact position and depth of the problem area. This helps ensure that any excavation or repair is precise and minimally invasive.

5. Review and recommendations: Once the inspection is complete, you can review the findings, go over the recorded footage (if applicable), and decide on the next steps—whether it’s scheduling a repair or simply keeping the video for peace of mind.

Common Problems Revealed by Sewer Cameras

A wide range of issues can be identified during a sewer camera inspection, including:

• Tree root intrusion: Roots are one of the most common causes of sewer line failure, particularly in older clay or concrete pipes.
  

• Pipe breaks or cracks: Crushed sections or fractures in the pipe can lead to leaks, soil erosion, or sewage backups.

• Offset joints: Pipe sections that have shifted out of alignment, often due to ground movement or age.

• Bellies or sags: Low spots where water and waste can collect, leading to frequent clogs.

• Blockages: Foreign objects, grease buildup, or debris can partially or fully block flow.

• Corrosion or deterioration: In cast iron or steel pipes, corrosion can cause rough surfaces and narrowing of the interior diameter.

When Should You Get a Sewer Camera Inspection?

Consider a sewer inspection when you are faced with one of these situations yourself.

1. Before Buying a Home

Sellers aren’t always aware of hidden issues—or may not disclose them. A sewer inspection gives you insight into the true condition of the property’s plumbing system.

2. Recurring Drainage Issues

If you regularly deal with clogs or slow drains, there may be an underlying structural issue. A camera inspection can uncover the root cause (literally).

3. Foul Odors

Unexplained sewage smells inside or around your home might indicate a break or clog in the sewer line.

4. Older Homes (Built Before 1980s)

Older homes often have clay, cast iron, or Orangeburg pipes, which are more prone to damage and deterioration.

5. Before Major Plumbing Repairs

Before excavating or replacing a pipe, a camera inspection can confirm where and what the problem is—saving time and money.

What Factors Should be Considered When Buying a Sewer Camera?

When you need to buy or rent a sewer camera, you should consider whether it includes the following features:

• Waterproof Camera – Often HD or 1080p, with built-in LED lights for clear footage even in total darkness.

• Flexible Cable – Lengths range from 50 to 200 feet or more, capable of maneuvering through turns and slopes.

• Monitor – Handheld or tablet-style screens display real-time footage; prioritize models with recording and logging capabilities.  

• Locator (optional but highly valuable) – Enables precise determination of the camera’s exact depth and location underground, enhancing repair accuracy.  

DIY-friendly kits are available for homeowners, while professionals may use more advanced systems with recording and reporting software.

How Much Does a Sewer Camera Inspection Cost?

The cost of a professional sewer camera inspection typically ranges from $100 to $500, depending on your location and the complexity of the system. Some plumbers include the service as part of a larger diagnostic visit, while others charge separately.

If you're a DIY homeowner, you can buy a sewer inspection camera for $100 to $2,000, depending on the features you need. For occasional use, a mid-range model with HD resolution, a long cable, and a locator function can be a great investment.
