A sewer scope inspection is a specialized service that utilizes a high-definition waterproof camera to examine the internal condition of a property’s main sewer line. This pipe carries all wastewater from the home to the municipal sewer main or a septic tank. Because these lines are buried deep underground, they remain out of sight and out of mind until a major backup occurs.
The Mechanics of the Sewer Scope Inspection
The process begins when an inspector locates a cleanout access point, usually found in the basement, crawlspace, or yard. A flexible fiber-optic cable equipped with a camera is fed through the line. As the camera travels toward the street, it transmits a live video feed to a monitor, allowing the inspector to see every inch of the pipe’s interior. This visual evidence is crucial because it reveals the exact material of the pipe, whether it is modern PVC, older cast iron, or even porous orangeburg.
Common Red Flags Underground
One of the most frequent issues discovered during an inspection is root intrusion. Trees are naturally drawn to the moisture and nutrients inside sewer pipes. Small cracks allow hair-like roots to enter, which then grow into massive blockages that catch debris and cause backups. Beyond roots, inspections often reveal “bellies” or low spots in the line. These occur when the soil shifts or settles, causing a section of the pipe to sag. Water and waste pool in these areas instead of flowing downstream, eventually leading to stubborn clogs and structural strain on the pipe joints.
Identifying Structural Failures
Older homes are particularly susceptible to pipe degradation. Cast iron pipes can suffer from heavy scaling or corrosion that narrows the passage, while clay pipes are prone to cracking or offsetting at the joints. An offset happens when two sections of pipe no longer align perfectly, creating a ledge that catches solid waste. In the worst-case scenarios, an inspection might reveal a total collapse of the line. Without a camera, a homeowner might only realize this exists when sewage starts backing up into the tubs and sinks, resulting in thousands of dollars in water damage and biohazard cleanup.
The Value of Foreknowledge
The primary benefit of a sewer scope is the power of information. Knowing the condition of the line allows a homeowner to perform preventative maintenance, such as professional hydro-jetting, before a total failure occurs. For a homebuyer, discovering a faulty sewer line during the due diligence period provides an opportunity to negotiate repairs or a price reduction with the seller. Repairing a main sewer line often involves excavation, sidewalk removal, and landscaping restoration, making it one of the most expensive fixes a property can require. Spending a small amount on an inspection today prevents a massive, unexpected bill tomorrow. It offers the ultimate peace of mind that the home is functioning properly from the inside out.
Frequently Asked Questions About Sewer Scope
How long does a typical sewer scope inspection take?
Most inspections are completed within thirty to sixty minutes, depending on the length of the line and the ease of access to a cleanout.
Is a sewer scope necessary for a brand-new home?
Yes, it is highly recommended. Construction debris, like leftover grout, heavy rocks, or even tools, can accidentally end up in the lines during the building process. Furthermore, heavy machinery driving over the yard can crush or disconnect pipes before the homeowners ever move in.
What happens if the camera cannot reach the city main?
If the camera is blocked by a massive clog or a collapsed section of pipe, the inspection is considered incomplete. This is a significant red flag that indicates immediate professional cleaning or repair is required to determine the full condition of the rest of the line.
Does a standard homeowners’ insurance policy cover sewer line repairs?
Generally, standard policies do not cover the wear and tear or gradual failure of a sewer line. Coverage is usually only provided if the homeowner has a specific “service line” endorsement or rider on their policy.
How often should a sewer scope be performed?
For older homes with mature trees on the property, an inspection every two to three years is a wise preventative measure. For newer homes, once every five to ten years is typically sufficient unless drainage issues arise.
