Sewer Scope Inspections: Why Proper Training and Experience Matter
What Home Buyers and Sellers Should Know Before Scheduling a Sewer Scope

When purchasing a home, there are many things to consider beyond the visible condition of the property. One area that can easily be overlooked is the underground sewer line.
A sewer scope inspection can be an extremely valuable service, helping identify potential problems that may otherwise go unnoticed during a traditional home inspection. However, as with any inspection service, the quality of the inspection depends heavily on the training, experience, equipment, and safety practices of the person performing it.
As someone who has spent years in the inspection industry and has experience working around other inspectors, I believe this is an area where home buyers and sellers should take a little extra time to understand what they are purchasing.
A sewer scope inspection involves more than simply inserting a camera into a sewer line and recording what appears on the screen.
The inspector needs to understand how to properly operate the equipment, recognize different types of piping, identify potential defects, interpret what the camera is showing, and determine when additional evaluation by a qualified plumbing professional may be necessary.
Some of the conditions that may be encountered include:
Recognizing these conditions takes more than familiarity with a camera. It requires an understanding of the sewer system itself and the ability to interpret the information correctly.
The camera is a tool. Knowing how to use that tool properly is what makes the inspection valuable.
One concern I have with the sewer scope industry is the availability of online training programs and relatively short courses that may give someone the impression they can quickly learn everything necessary to perform this service.
I understand that training programs are designed to introduce inspectors to equipment, procedures, and inspection techniques. They can be a valuable starting point.
However, in my opinion, completing an online course or attending a short training class should not automatically be considered sufficient preparation for independently performing sewer scope inspections.
I have seen training opportunities advertised that involve approximately eight hours of live instruction. While a live class can certainly provide useful information, I believe this is a service that deserves a more comprehensive approach to education and practical experience.
There is a difference between learning how to operate a camera and developing the knowledge necessary to perform a reliable sewer scope inspection.
Inspectors should take the time to understand the systems they are evaluating, learn how to recognize common defects, become familiar with the limitations of their equipment, and gain practical experience before offering this service to clients.
In my opinion, proper training should be viewed as an ongoing process, not simply a certificate obtained after completing a short course.
Another concern is the importance of proper personal protective equipment, commonly referred to as PPE.
Sewer systems can expose inspectors to biological contaminants, wastewater, and other potentially hazardous materials.
Depending on the conditions encountered, appropriate protective equipment may include:
The specific PPE required will depend on the conditions, the equipment, and the potential exposure involved.
Inspectors should also understand how to handle, transport, and clean their equipment without unnecessarily exposing themselves, their clients, or their vehicles to contamination.
This is not something that should be taken lightly.
A sewer scope inspection is not simply another service that can be performed without considering the potential hazards involved.
Protecting the inspector and preventing the spread of contamination should be an essential part of every sewer scope inspection.
Sewer scope inspections have become increasingly popular, and many home inspectors now offer this service as an additional option during a home inspection.
There is nothing wrong with inspectors expanding their services. In fact, offering additional services can provide tremendous value to clients when those services are performed properly.
However, I believe inspectors should be careful not to offer sewer scopes simply because they represent an opportunity to generate additional revenue.
The important question is not whether an inspector offers sewer scopes.
The important question is whether the inspector has the necessary training, experience, equipment, and knowledge to perform the service competently.
Before scheduling a sewer scope inspection, I encourage home buyers and sellers to ask a few questions:
Ask about the inspector's training and whether it includes practical instruction and experience with sewer inspection equipment.
Experience matters. Ask whether the inspector has performed this service regularly and understands the types of conditions commonly encountered.
A professional sewer scope inspection should involve appropriate equipment for the conditions being evaluated.
The inspector should be able to explain how they protect themselves, handle contaminated equipment, and maintain appropriate sanitation procedures.
Ask whether the inspector can explain the findings, provide documentation, and identify when further evaluation by a qualified plumbing professional is recommended.
These questions can help you make a more informed decision when choosing someone to perform this important service.
One of the primary reasons I believe sewer scope inspections are so important is the potential financial impact of an underground sewer line problem.
Unlike many components of a home, the sewer line is generally not visible during a standard home inspection.
A defect may exist underground without producing obvious symptoms inside the home.
Depending on the location, depth, accessibility, and extent of the damage, repairing or replacing a sewer line can become a significant expense.
For a home buyer, discovering a sewer line problem after closing can create an unexpected financial burden.
For a seller, identifying a problem before listing or completing a transaction may provide an opportunity to address the issue, obtain estimates, or disclose the condition appropriately.
For property owners who are not buying or selling, a sewer scope may also provide useful information about the condition of an existing sewer line.
However, it is important to understand that a sewer scope is a visual inspection of the portions of the sewer line that can be accessed and evaluated with the equipment.
It does not guarantee that every defect will be identified or that the sewer line will remain problem-free.
The quality of the inspection, the accessibility of the piping, and the limitations of the equipment all matter.
Based on my experience in the inspection industry and my observations of the services being offered, I believe sewer scope inspections deserve more attention when it comes to training, safety, and professional responsibility.
I am not suggesting that every inspector offering sewer scopes is improperly trained or that every short training program is without value.
There are qualified professionals who perform this service properly and provide excellent information to their clients.
My concern is that the availability of equipment and the opportunity to generate additional income can sometimes make a service appear easier to offer than it actually is.
A sewer scope inspection is an important part of evaluating a property, and the person performing it should understand the responsibility involved.
Home buyers and sellers are relying on the inspector to provide information that may influence a significant financial decision.
That responsibility should not be taken lightly.
At The Inspection Co, we believe that inspection services should be approached with the proper knowledge, preparation, and professional responsibility.
Our goal is to help clients understand the condition of the property they are buying, selling, or maintaining.
When considering a sewer scope inspection, I encourage everyone to look beyond the price and ask about the qualifications of the person performing the service.
A properly performed sewer scope can provide valuable information and help identify potential concerns before they become unexpected problems.
But the value of that inspection depends on the person behind the camera.
Do your research. Ask questions. Make sure the person performing your sewer scope understands the importance of proper training, safety, and accurately communicating their findings.
When it comes to your home and your investment, choosing the right professional matters.
