A sewer video inspection is one of the best ways to protect yourself when buying a home because it shows you exactly what’s going on inside the sewer line. The camera reveals problems like cracks, blockages, or tree roots before you sign the papers, so you don’t get stuck with expensive repairs later. What makes it so valuable is that there’s no guessing. You see the condition of the pipes with your own eyes. That means less worry, more leverage if repairs are needed, and the confidence that you’re making a smart purchase.

What Is a Sewer Video Inspection?

A sewer video inspection is a process where a professional plumber uses a specialized waterproof camera connected to a long, flexible cable to explore the inside of sewer pipes. The live video feed is displayed on a monitor, allowing both the plumber and homeowner to see the actual condition of the line.

This inspection can reveal:

• Clogs or buildup from grease, soap, or debris.
• Cracks and breaks in older pipes.
• Tree root intrusion is one of the most common causes of sewer blockages.
• Corrosion in metal pipes weakens the system over time.
• Collapsed sections of pipe that restrict flow.

Unlike traditional methods that required excavation, a sewer camera inspection is non-invasive. No digging is needed just to “see” what’s happening underground. Instead, the camera is inserted through a cleanout or access point and travels through the line, recording and transmitting clear visuals.

Why Sewer Inspections Matter When Buying a Home

When people think about home inspections, they usually imagine structural checks, electrical testing, or looking for mold. Yet, the sewer system is often overlooked, even though it’s one of the most critical parts of a property.

If you buy a home without checking the sewer line, you risk inheriting someone else’s problems. A sewer replacement can cost thousands—sometimes more than $10,000, depending on the extent of damage and the location.

A sewer inspection before purchase helps you:

• Avoid unexpected costs after moving in.
• Negotiate with the seller if problems are found.
• Plan for maintenance instead of being surprised by emergencies.
• Understand the system’s lifespan—older homes often have clay or cast iron pipes that may be nearing the end of their usefulness.

Common Sewer Problems Found in Home Purchases

Here are some of the issues that sewer cameras often reveal:

1. Tree Root Intrusion

Tree roots naturally seek out water sources, and small cracks in sewer pipes provide an entry point. Once inside, roots grow and expand, causing clogs, backups, and even pipe collapse.

2. Cracks and Breaks in Pipes

Pipes can crack due to shifting soil, ground settling, or pressure from above. These cracks can leak sewage into the yard or foundation area, leading to unpleasant odors and health hazards.

3. Pipe Corrosion

Homes built with cast iron or galvanized pipes may experience corrosion. Over time, corrosion reduces the pipe’s thickness, increasing the risk of leaks and breaks.

4. Bellied Pipes

A belly occurs when part of a sewer pipe sags downward, creating a low spot where waste and water collect. This standing water leads to repeated clogs and accelerated pipe deterioration.

5. Collapsed or Misaligned Pipes

In severe cases, pipes may shift or collapse entirely. Without a camera inspection, this would only become obvious after frequent sewage backups.

Benefits of a Sewer Video Inspection Before Closing

Getting a sewer inspection before buying a house offers major benefits:

• Full Transparency: You’ll see the exact condition of the sewer line on camera, so there’s no relying on guesswork.
• Stronger Negotiating Power: If issues are found, you can request repairs, replacements, or price reductions from the seller.
• Peace of Mind: Knowing your sewer system is healthy means one less thing to worry about during your home purchase.
• Preventing Surprises: Instead of moving in and facing immediate plumbing problems, you’ll know exactly what to expect.
• Cost Savings: Spending a few hundred dollars on an inspection can save you from thousands in repairs.

How Sewer Inspections Work Step by Step

1. Access Point Location – The plumber finds a cleanout or other entry point into the sewer line.
2. Camera Insertion – A high-definition waterproof camera attached to a cable is fed into the pipe.
3. Live Video Monitoring – The plumber views the footage in real time on a monitor, identifying blockages, cracks, or root intrusion.
4. Recording & Documentation – Many inspections include video recordings or images so you can review the results yourself.
5. Professional Assessment – The plumber provides a detailed explanation of any problems and recommends solutions.

How Sewer Video Inspections Can Save You Money

Imagine buying a home and discovering two months later that the main sewer line is collapsed. The repair could cost anywhere from $5,000 to $20,000, depending on the severity and whether trenchless replacement is possible.

By investing in a sewer video inspection before purchase, you:

• Identify problems before signing the contract.
• Use the findings as leverage to negotiate lower repair costs or a lower asking price.
• Budget properly if you decide to move forward, knowing future repairs are likely.

Older Homes vs. Newer Homes: Why Inspections Are Crucial

• Older Homes: Properties built before the 1980s may have clay, cast iron, or Orangeburg (a type of tar paper) pipes. These materials are prone to deterioration and collapse. Sewer video inspections are essential here.
• Newer Homes: Even modern PVC systems can experience poor installation, shifting soil, or construction damage. Inspections catch these problems early.

No matter the home’s age, skipping a sewer inspection means taking on unnecessary risk.

When Should You Schedule a Sewer Video Inspection?

• Before closing on any home purchase.
• If the home is more than 20–30 years old.
• If the property has large trees nearby (possible root intrusion).
• If you notice slow drains, gurgling toilets, or foul odors during your walkthrough.
• If the seller cannot provide recent inspection reports.

Final Thoughts

A sewer video inspection is one of the smartest, most cost-effective steps you can take before buying a home. It provides clear evidence of the sewer system’s condition, protects you from hidden repair bills, and gives you the confidence to move forward with your purchase. Whether you’re buying an older home with clay pipes or a newer build, this inspection ensures you won’t be left with unpleasant surprises after moving in.

When you’re making one of life’s biggest investments, don’t leave the condition of your sewer system up to chance. A quick, professional camera inspection today could save you from years of headaches and thousands of dollars tomorrow.
