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:
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.

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:
How Sewer Inspections Work Step by Step
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?
You should schedule a sewer video inspection before closing on any home purchase, especially if the property is more than 20 to 30 years old or surrounded by large trees that could cause root intrusion. It’s also important to get the inspection if you notice slow drains, gurgling toilets, or unpleasant odors during your walkthrough, as these can indicate hidden sewer issues. If the seller cannot provide a recent inspection report, it’s best to arrange your own. Doing this early ensures you know the true condition of the sewer system and can avoid expensive repairs after buying the home.
