Buying a home is one of the biggest investments you will ever make. You check the roof, furnace, electrical system, and foundation. But there is one major system that most standard home inspections don’t fully inspect—your underground sewer line.
In this guide, we’ll break down hydro jetting vs chemical drain cleaners, explain why hydro jetting is the better long-term solution, and help Idaho homeowners understand when it’s the right choice for their plumbing system.
At The Rooter Guys Plumbing, we regularly help homeowners and homebuyers discover hidden sewer line problems before they become disasters.
For about the cost of dinner for two, a professional sewer scope inspection can reveal major problems that could otherwise cost $5,000 to $15,000 to repair.
The Nightmare Under the Surface
Imagine finding your dream home.
- The inspection report looks great.
- The kitchen is remodeled.
- The roof is new.
- Everything seems perfect.
Then, one week after moving in, sewage backs up into your basement.
Unfortunately, this situation happens more often than most homeowners realize. The problem is usually hidden underground inside the sewer lateral—the pipe that connects your home’s plumbing to the city sewer system or septic tank.
Many homes in North Idaho still have older clay or cast-iron sewer pipes that can crack, shift, or collapse over time.
Without a sewer line inspection, these problems remain invisible until something goes seriously wrong.
What Is a Sewer Camera Inspection?
A sewer camera inspection uses specialized plumbing equipment to inspect the inside of your sewer line without digging up your yard.
A plumber inserts a high-definition, waterproof camera, attached to a flexible cable, into your drain system. The camera travels through the sewer pipe and sends real-time video back to a monitor.
This allows plumbers to inspect the entire sewer line from the house to the city connection or septic tank.
Think of it like a medical endoscopy—but for your plumbing system.
Instead of guessing where a problem might be, a sewer scope inspection lets us see exactly what is happening inside the pipe.
Why Home Buyers Should Always Get a Sewer Scope Inspection
Many home buyers assume the standard home inspection covers everything, but sewer lines are often excluded from a typical inspection report.
That means a home could pass inspection while still hiding major sewer problems underground.
A sewer camera inspection for home buyers can identify:
- Cracked or collapsed pipes
- Tree root intrusion
- Pipe offsets or shifting
- Severe buildup or blockages
- Sewer pipes “bellies” that collect waste
Spending $150 to $300 on a sewer scope inspection could save you thousands on unexpected repairs.
In some cases, buyers even use the inspection results to negotiate repairs or price reductions before closing on the home.
3 Signs You May Need a Sewer Line Inspection
Even if you’re not buying a home, there are several warning signs that your sewer line may need a professional camera inspection.
1. The “Phantom Gurgle.”
If you hear bubbling sounds from the toilet when someone runs the shower or washing machine, that can indicate air trapped in the sewer line due to a blockage or restriction.
2. Soggy Patches in Your Yard
If one area of your lawn stays unusually green, wet, or soft, it may indicate a leaking underground sewer pipe.
This is especially common in older sewer lines where roots or pipe cracks allow wastewater to escape.
3. Recurring Drain Clogs
If you call a plumber every six months for the same clogged drain, you likely don’t have a simple clog.
You probably have a larger structural sewer problem that needs to be identified with a camera inspection.
The Three Biggest Sewer Line Problems We Find
During sewer camera inspections, three issues recur in older homes throughout North Idaho and Eastern Washington.
Root Intrusion
Tree roots are constantly searching for water sources underground.
Even the smallest crack in a sewer pipe can allow roots to enter. Once inside, they expand until the pipe is completely blocked.
Root intrusion is one of the most common causes of sewer line backups.
Pipe Offsets
In areas with shifting soil, sections of sewer pipe can move out of alignment.
When one pipe section slips slightly lower than another, it creates a small lip inside the pipe. This lip accumulates debris, toilet paper, and waste over time, eventually leading to repeated blockages.
Sewer Pipe Bellies
A sewer pipe “belly” is a low spot where the pipe has sagged.
Instead of flowing smoothly to the main sewer connection, water pools in this low section. Waste settles there, slowly building up until it creates a permanent blockage.
A sewer camera inspection is the only reliable way to detect this problem.
How Much Does a Sewer Camera Inspection Cost?
One of the biggest surprises for homeowners is how affordable a sewer inspection actually is.
Most sewer camera inspections cost between:
- $150 – $300 for a standard inspection but the rooter guys offer it free with sewer line removal
Compared to the potential cost of replacing a sewer line—which can range from $5,000 to $15,000 or more—this is one of the smartest preventative investments a homeowner can make.
The Bottom Line: Knowledge is Power
A sewer line is one of the most important systems in your home, but it’s also one of the most overlooked. A professional sewer camera inspection gives homeowners something incredibly valuable:
Certainty.
Whether you’re buying a home, dealing with recurring plumbing issues, or simply want peace of mind, a sewer scope inspection can reveal hidden problems before they turn into expensive emergencies. If you want to protect your investment and avoid costly surprises, scheduling a sewer line inspection is a simple step that could save you thousands.
