When buying a home, it is easy to focus on what you can see, such as the roof, foundation, electrical system, HVAC, plumbing fixtures, and interior condition. But one of the most important parts of the home’s plumbing system is buried underground: the main sewer line. A sewer scope inspection helps homebuyers get a clearer look at this hidden system before closing.
Key Takeaways
A sewer scope inspection helps evaluate the accessible underground sewer line before buying a home.
Common issues include root intrusion, cracks, offsets, bellies, corrosion, debris buildup, and standing water.
Identifying sewer line concerns before closing may help buyers avoid unexpected repair costs after purchase.
What Is a Sewer Scope Inspection?
A sewer scope inspection provides a closer look inside the accessible main sewer line using a specialized video camera. The camera is inserted through an accessible cleanout or other approved access point and advanced through the line to evaluate visible conditions inside the pipe. This allows the inspector to observe the general condition of the line, identify the pipe material where visible, and look for conditions that may restrict drainage or lead to future problems. We define a “sewer scope” as a video inspection of the lateral sewer line from the home toward the city connection, HOA tap, or septic tank, with the purpose of identifying visible defects and pipe materials.
Why Sewer Lines Matter During a Home Purchase
This inspection is especially valuable because the sewer line is commonly the homeowner’s responsibility to maintain and repair. Even though part of the line may run under the yard, driveway, walkway, landscaping, or other exterior areas, issues within that buried pipe can still become the property owner’s responsibility after purchase. A problem that is not discovered before closing can quickly become an expensive and disruptive repair.
What Can a Sewer Scope Inspection Find?
A sewer camera inspection can help identify conditions such as root intrusion, debris buildup, standing water, damaged pipe sections, cracks, offsets, separated joints, crushed piping, corrosion, and bellies in the line. A “belly” occurs when a low section of pipe allows water and waste to settle instead of flowing properly. Over time, this can contribute to repeated clogs or slow drainage. Some common concerns found in sewer lines, include root infiltration, offsets, cracks, breaks, corrosion, sagging, and flow restrictions depending on the pipe material.
Are Older Homes More Likely to Have Sewer Line Problems?
Older homes can be more likely to have sewer line concerns, especially if the property has clay, cast iron, concrete, or other aging pipe materials. Clay pipe may be more vulnerable to root entry or joint separation. Cast iron can corrode and restrict flow as it ages. Concrete piping can deteriorate or leak at joints. Newer homes are not automatically free of problems either. Improper installation, poor pipe bedding, settlement, or damage during backfilling can create issues even in newer plastic piping.
What a Sewer Scope Inspection Does Not Do
A sewer scope inspection does not repair the line, clear blockages, or guarantee future performance. It is a visual inspection of the accessible portions of the underground pipe at the time of inspection. However, the information it provides can be extremely useful. If defects are observed, a licensed plumbing contractor can further evaluate the concern, provide repair options, clean the line if needed, or locate the affected section for correction.
Is a Sewer Scope Inspection Worth It?
For homebuyers, a sewer scope can provide added confidence before moving forward with a purchase. Sewer line repairs can be costly, especially when excavation, driveway removal, landscaping disturbance, or pipe replacement is needed. Finding out about a major sewer line concern after closing can be frustrating and expensive. Having the line evaluated before purchase gives buyers a better understanding of the property and may help them make more informed decisions.
A sewer scope is a smart add-on for older homes, homes with mature trees, properties with known drainage concerns, homes with additions or exterior improvements, and any property where the buyer wants a more complete picture of the plumbing system. While the sewer line may be hidden underground, it plays a major role in the proper function of the home. A sewer camera inspection helps bring that hidden system into view.
