What is a Sewer Line Video Inspection?

A sewer line video inspection is a modern diagnostic method used by plumbers to examine the condition of underground sewer pipes without digging or disrupting the surrounding area. Using specialized equipment, plumbers can capture real-time footage of the interior of your sewer lines, allowing them to pinpoint problems such as blockages, cracks, or tree root intrusion.

Explanation of Sewer Line Video Inspection Technology:

This inspection method relies on a small, high-definition camera attached to a long, flexible cable. The camera is placed into the sewage system via an access point, such as a cleanout. It then moves through the pipes, sending live video to a display. This allows the plumber to see the inside of the sewer line in great detail and identify any issues.

Equipment Used:

• High-definition camera: Provides clear, detailed images of the pipe’s interior.
• Flexible cable: The cable is long enough to navigate the sewer system, flexible enough to move around bends, and strong enough to endure the sewer’s environment.
• LED lights: Bright LED lights are frequently included within the camera to highlight the inside of the pipes, guaranteeing a good image even in dimly lit underground spaces.
• Monitor and recording equipment: The footage is displayed in real-time on a monitor, allowing the plumber and homeowner to observe the inspection. The video can also be recorded for further analysis and repair planning.

When is a Sewer Line Video Inspection Needed?:

• Frequent blockages: If you’ve been experiencing frequent clogs or backups in your plumbing, a video inspection can identify whether there is an underlying issue, such as a blockage or damage.
• Slow drains: Slow drains that don’t disappear indicate a blockage or accumulation in your sewage system.
• Buying or selling a house: Examining the sewage line might provide essential details about the plumbing system on the site. For potential buyers, it ensures there are no hidden issues, while sellers can provide proof that their system is in good condition.
• Older homes: Homes with aging plumbing systems are more prone to corrosion, tree root intrusion, or other forms of deterioration, making a video inspection an excellent preventative measure.

The Inspection Process

The sewer line video inspection process is straightforward and designed to be minimally invasive while providing a thorough look at the condition of your plumbing. It begins with accessing the sewer line through an existing opening, typically called a cleanout, and then using a camera to inspect the interior of the pipes.

How the Camera is Inserted into the Sewer Line Through a Cleanout

A cleanout is an access point in your plumbing system that allows plumbers to reach the main sewer line. It’s usually located near the house or in the yard. Once the cleanout is located and opened, the plumber inserts the high-definition camera into the sewer line, which is attached to a long, flexible cable. The cable’s flexibility allows it to navigate the pipe’s twists and turns while the camera transmits live video as it moves through the sewer line.

Real-Time Footage Allows Plumbers to See the Condition of the Pipes

The plumber may see the state of the pipes in great detail by watching the real-time film that the camera delivers to a display as it passes through the sewage system. This live feed helps diagnose issues and can be recorded for future reference. Homeowners can watch along as the inspection takes place, which allows them to understand the problems better.

Common Issues Found

During the inspection, plumbers often encounter many problems that would be difficult to diagnose without this advanced technology. Common issues include:

• Blockages: The most common issues seen during a sewage line examination are blockages from dirt, oil, or foreign objects.
• Tree Root Intrusion: Nearby tree roots can grow into the sewer lines, causing significant damage. The video inspection can clearly show where roots have infiltrated the pipe and the extent of the damage.
• Pipe Deterioration: Older homes may have pipes made of materials prone to corrosion and deterioration over time. The camera can reveal areas where the pipe walls have become weak or have started to erode.
• Cracks and Leaks: Cracks in the pipes or misalignments between pipe sections can lead to leaks and other problems. The video inspection helps plumbers locate these issues so that repairs can be made precisely where needed.

Benefits of a Sewer Line Video Inspection

A sewer line video inspection offers numerous advantages for homeowners facing plumbing issues or those who want to avoid potential problems. This advanced diagnostic tool makes identifying sewer line problems more precise and saves time and money by eliminating guesswork.

Non-invasive and Cost-effective Diagnostic Tool

One of the primary benefits of a sewer line video inspection is its non-invasive nature. Unlike traditional methods, which often require extensive digging to locate and diagnose problems, this inspection uses a small camera to get a clear view of the inside of the pipes. This means there is no need to tear up lawns, driveways, or floors to assess the condition of your plumbing. Additionally, because the inspection is highly targeted, it’s a more cost-effective option, avoiding the expenses that come with unnecessary exploratory digging or trial-and-error repairs.

Avoids Unnecessary Digging and Disruption

Without a video inspection, identifying the location of sewer line issues often involves disruptive and labor-intensive digging. This process can be time-consuming and costly, mainly if the problem is located in an area that requires significant excavation, such as under a driveway or yard. With a sewer line video inspection, the issue’s exact location is identified with pinpoint accuracy, meaning that any digging is minimized, saving time and preserving the property’s landscape.

Provides an Accurate Diagnosis, Saving Money on Unnecessary Repairs

Because the video camera delivers real-time footage of the pipes inside, the plumber can accurately diagnose on the spot. Whether it’s a blockage, crack, or tree root intrusion, the plumber knows precisely the issue and its location. This precise diagnosis prevents unnecessary repairs, as you won’t be fixing something that isn’t broken. It also allows the plumber to recommend the most appropriate and cost-effective solution for your problem, reducing repair costs.

Can Be Used for Both Preventative and Reactive Maintenance

Sewer line video inspections are valuable for addressing existing problems and preventing future ones. If you’ve been experiencing slow drains, frequent blockages, or backups, the inspection can provide insight into the cause and allow for quick and effective repairs. However, it’s also a powerful tool for preventive maintenance. Conducting a video inspection before problems arise—especially in older homes or properties surrounded by large trees—can identify potential issues early, such as tree roots growing toward the pipes or areas of deterioration. Addressing these before they escalate can prevent costly emergency repairs down the road.

What the Plumber Looks For During the Inspection

During a sewer line video inspection, the plumber carefully reviews the footage captured by the high-definition camera as it travels through the sewer pipes. The goal is to assess the system’s overall condition and identify any issues that may be causing problems or could lead to future complications. Here are the key things plumbers look for during the inspection:

Signs of Damage or Deterioration

Sewer line wear and tear is frequently seen in older homes or buildings with deteriorating pipes. Therefore, plumbers check the line for these indications. Over time, materials like cast iron, clay, or even PVC can break down due to environmental factors or usage. The video footage allows the plumber to identify areas where the pipes start to deteriorate, develop weak spots, or show visible signs of damage. This early detection of deterioration can prevent more severe problems, such as pipe bursts or significant blockages.

Misalignments, Collapsed Sections, or Cracks in the Pipe

One of the most critical aspects of the video inspection is spotting structural issues in the sewer line. The plumber checks for misalignments when different pipe sections shift out of place due to ground movement or settling. Additionally, the camera helps identify collapsed sections where the pipe may have caved in or become severely damaged. Cracks in the pipe walls are also a common problem, especially in older systems. These cracks can lead to leaks, causing environmental damage or contamination if not repaired promptly.

Obstructions Like Tree Roots, Grease, or Debris Build-Up

Plumbers also search for impediments that can prevent wastewater from passing through the sewer system. Tree roots are a common offender because they can grow inside pipes in search of moisture and nutrition. These roots can seriously clog pipes and potentially harm them as they grow. Another frequent problem is grease build-up, frequently brought on by incorrectly pouring fats, oils, and grease down the drain. Debris, such as wipes, paper towels, and other foreign objects, can accumulate, creating blockages that disrupt the sewer system. Identifying these obstructions early allows for targeted cleaning and repair, preventing backups and costly damage.

Indications of Pipe Sagging or Corrosion

Pipe sagging, also known as a “belly,” occurs when a section of the pipe dips due to ground movement or improper installation. This creates a low spot where wastewater can collect, leading to slow drains and frequent clogs. Plumbers inspect the sewer line for signs of sagging, often requiring pipe re-leveling or replacement to prevent ongoing issues. Corrosion is another problem usually seen in older metal pipes. Internal pipe corrosion, brought on over time by exposure to chemicals and water, may cause leaks or collapses. Early corrosion detection enables proactive replacement or repair.

What Happens After the Inspection?

Once the sewer line video inspection is complete, the plumber will review the results with you. This includes reviewing the footage, identifying issues, and discussing possible solutions. Here’s what to expect after the inspection:

Receiving a Detailed Report and Video Footage

• A summary of findings: A clear breakdown of any issues detected, such as blockages, cracks, or pipe misalignments.
• Video footage: The recorded video from the inspection is often included so that you can review the sewer line’s condition yourself. Some plumbers may provide this digitally or on a physical storage device.
• Visual documentation: Screenshots or images from the video highlighting problem areas.

Recommendations for Repairs or Maintenance if Problems are Found

• Cleaning or clearing blockages: If the issue is caused by debris or tree roots, the plumber may recommend a thorough cleaning using hydrojetting or another method to clear the obstruction.
• Repairs for cracks or misalignments: Cracked or misaligned pipes may need to be repaired to prevent leaks or further damage.
• Preventative maintenance: Sometimes, the plumber may suggest regular inspections or treatments, such as tree root inhibitors, to avoid future issues.

Discussing the Next Steps for Repair

Once the plumber has reviewed the report with you, the next step is to decide on the appropriate repair method. Some standard options include:

Repair Method	Description	When It’s Used
Trenchless Repair	This method uses minimal digging and involves inserting a liner into the damaged pipe to seal cracks and leaks.	Used for minor cracks or leaks without significant blockages.
Pipe Replacement	In severe damage, replacing certain pipe parts completely could be necessary. Depending on the situation, this could entail trenchless techniques or digging.	It is required for collapsed sections or severely deteriorated pipes.
Cleaning (Hydro-Jetting)	A high-pressure water jet clears blockages in the sewer line caused by grease, debris, or tree roots.	It is ideal for blockages or routine maintenance.

Timelines and Costs Associated with Various Repair Options

Depending on the severity of the problem, the plumber will give you an estimate of how long repairs will take and the associated costs. Here’s a general breakdown of what to expect:

Repair Option	Estimated Timeframe	Cost Range
Trenchless Repair	1-2 days	$3,000 – $6,000
Pipe Replacement	3-5 days (may vary based on scope)	$5,000 – $15,000 (location-dependent)
Cleaning (Hydro-Jetting)	A few hours	$500 – $1,000

Preparing for a Sewer Line Video Inspection

How Homeowners Can Prepare (Clearing Access to Cleanouts)

The first step in preparing for a sewer line video inspection is to ensure the plumber has easy access to the sewer cleanout. A cleanout is typically located outside near the home or sometimes in the basement. To prepare:

• Clear any obstructions: Move any plants, outdoor furniture, or other objects that might block access to the cleanout.
• Locate the cleanout: If you need help finding where it is, review the property documents or ask the plumber to help you upon arrival.
• Keep pets away: If you have pets, ensure they are secured to avoid distractions or disruptions during the inspection.

Timing: How Long the Inspection Typically Takes

The length and quality of the pipes determine how long a sewer line video inspection takes. However, on average, the process takes 30 minutes to an hour. In cases where the system is complex, or the plumber needs to investigate multiple sections, it may take a little longer. The plumber will carefully guide the camera through the pipes to examine all potential problem areas thoroughly.
