Most homebuyers and homeowners don’t think about their sewer lines. Buried underground, it remains unnoticed until something goes wrong. A clogged or broken sewer line doesn’t usually show up during a quick walkthrough. You need a sewer scope inspection to know if the system is in good condition.

Especially when buying a new home, sewer inspection should not be ignored. In this blog, we’ll explain how a sewer scope inspection works and whether it makes sense for your home purchase.

Let’s Understand Sewer Scope Inspection First

A sewer scope inspection is a specialized inspection in which a small, waterproof camera is inserted into the home’s main sewer line. The camera travels through the pipe and sends live video back to the inspector, helping to see:

Condition of the sewer pipe
Blockages or buildups
Cracks, breaks, or collapses
Root intrusion
Bellies or low spots
Old or failing pipe materials

In short, it lets us see what’s going on underground. It is not included in a standard home inspection.

Why a Standard Home Inspection Doesn’t Include Sewer Scope

Many homebuyers ask this question. During a regular home inspection, home inspectors run water in sinks and tubs, flush toilets, or check for leaks inside the home. What they can’t see is the condition of the underground sewer line.

Water flowing during the inspection doesn’t mean the sewer line is healthy. A pipe can partially collapse, have roots growing inside, or be on the verge of failure and still drain normally for the time being.

What Happens During a Sewer Scope Inspection

The process of sewer scope inspection is simple. Here is what happens during an inspection:

The inspector locates an accessible sewer cleanout
A camera is fed into the sewer line
The camera travels toward the main sewer connection
The inspector watches the pipe condition in real time
Findings are recorded and documented

There’s no digging, no damage, and no mess in this whole process. It usually takes 20 to 40 minutes, depending on the length of the line and what’s found.

Common Problems Found in Sewer Scope Inspection

The inspection of the sewer line helps reveal what’s going on beneath the surface. Here are some common problems that often lead to system malfunctions.

Tree Root Intrusion

Tree roots are one of the most common sewer problems. Roots naturally seek moisture, and tiny pipe cracks are an open invitation for them. Roots can:

Slower the drainage
Cause recurring clogs
Eventually, break the pipe

Roots are especially common in older homes and properties with mature trees.

Cracked, Broken, or Collapsed Pipes

Being buried underground, sewer pipes are exposed to:

Soil movement
Heavy loads
Freezing and thawing
Aging materials

Cracks can start small and worsen over time. A collapsed sewer line is a major repair that often requires excavation.

Bellies (Low Spots)

A belly is a section of the pipe that has sunk and now holds standing water. This can lead to:

Frequent clogs
Waste buildup
Increased risk of backups

Bellies usually don’t resolve on their own and can worsen over time.

Old or Outdated Pipe Materials

Some older sewer pipes were made from materials that don’t age well, such as:

Clay
Cast iron
Orangeburg (fiber pipe)

These materials are more prone to cracking, corrosion, and collapse. A sewer scope inspection helps identify the pipe’s material and overall condition.

Improper Repairs or Connections

Sometimes inspectors find:

Poorly done past repairs
Misaligned pipe joints
Foreign object inside the line

These issues often go unnoticed, leading to leakage below the surface. It can cause backup and hygiene issues at your property.

Is a Home-Buying Sewer Inspection Necessary

It is not always required, but, as with a regular home inspection, you should consider getting one. It helps visualize the property’s hidden system. Knowing the condition of the sewer line, you can make better purchase decisions. Here are a few situations when sewer scope inspection is recommended:

The home is older
The home has large or mature trees
The home has a history of sewer backups
The home has been vacant for a long time
You have noticed a bad odor or slow drains
You want to avoid surprise repairs after closing

A home-buying sewer inspection gives buyers information before they commit.

Sewer Scope Inspection to See Clearly

A sewer scope inspection is among the most important parts of the home-buying process. It helps uncover problems that standard inspections miss and gives buyers a clearer picture of what they’re really purchasing.

If you are buying a new home or haven’t checked your sewer line for years, book an inspection from The Brickkicker at the earliest possible time. Schedule your inspection and make sure the hidden system isn’t in store for a costly surprise.
