What a Sewer Camera Inspection Actually Shows You

A sewer camera inspection results report shows you the inside of your sewer line in real time, a recorded look at the actual pipe under your yard, not a guess or a sales pitch.

Acclaimed Drain And Plumbing Solutions, LLC offers sewer camera inspections across Tucson and Southern Arizona, showing you what’s happening underground before anyone picks up a shovel.

Visualizing these subterranean conditions provides the necessary clarity to determine if a comprehensive sewer scope inspection is required to address deeper structural concerns.

Real-Time Video and What the Technician Sees

A flexible camera travels through your sewer line while it records.

Here is what the feed captures:

• Pipe material and age clues, like clay, cast iron, or PVC
• Blockage and buildup blocking flow
• Cracks, leaks, and damaged joints

Common Sewer Camera Inspection Findings and What They Mean

Most sewer camera inspection findings fall into a few clear groups. Knowing the group helps you understand the repair recommendation you get.

Blockages, Grease Buildup, and Foreign Objects

Blockages and obstructions are the most common finding. Grease buildup narrows the pipe over time. Foreign objects like wipes, toys, or roots catch debris and cause slow drainage.

Many of these clear with drain clearing or hydro jetting.

Tree-Root Intrusion and Structural Damage

Tree-root intrusion is different. Roots enter through small cracks, grow, and cause recurring drain problems, and can crack the pipe outright.

Structural damage includes:

• Cracks and leaks in the pipe wall
• Damaged joints where sections meet
• Pipe separation between two sections

These findings often point to repair or replacement. Some cases suit trenchless sewer liner work.

How to Read a Sewer Scope Report Line by Line

A sewer scope report is usually two to five pages but dense. Most confusion comes from not knowing which parts are raw evidence and which are the technician’s interpretation. Read it in this order.

1. Header and access notes

The top should state the date, property address, access point used (cleanout, roof vent, or pulled toilet), and direction of travel. Direction matters: most reports run from the house toward the municipal main, so a finding at 12 feet is near the foundation and one at 60 feet is out under the yard or street.

2. Pipe material, diameter, and length

The inspector should identify the pipe material, clay tile, cast iron, galvanized steel, orangeburg, concrete, ABS, or PVC, and the nominal diameter, typically 3-inch, 4-inch, or 6-inch for a residential lateral. Material matters: a hairline crack in modern PVC usually means something different than a crack in 60-year-old cast iron, which tends to widen as the pipe graphitizes.

3. Distance markers and timestamps

Every finding should carry a distance from the access point, usually in feet, and a timestamp matching the video. The distance tells a repair crew where to dig or send a liner, and the timestamp lets you pull up the exact footage.

4. Photos and video clips

A credible report includes still photos or short clips of each defect, not just a written note. Look for a clear image of the defect and, where possible, a wider shot showing its position relative to a joint or fitting. If the report says “cracked pipe” but shows no image, ask for the clip.

5. Severity rating and defect codes

Many inspectors use a rating scale, and some use NASSCO PACP defect codes, “CR” for crack, “RT” for roots, “OB” for obstruction, each mapping to a defined defect type and severity band. You don’t need to memorize the codes, but you do need to know whether the rating is the inspector’s own scale or a standardized one.

6. Technician notes and recommendations

The notes section is where interpretation lives. Read it critically. A good note ties a recommendation to a specific finding at a specific distance, for example, “root intrusion at 34 feet, moderate, recommend cabling and re-inspection in 12 months.” A weak note jumps from a finding to a big-ticket recommendation without explaining the link.

A quick annotated example

A typical entry on a well-written report reads something like this:

Distance 28.4 ft, Cast iron, 4-inch, RT (roots), moderate. Roots visible at a joint, occupying roughly 30 percent of the pipe opening. Flow not blocked. Recommend cabling the line and re-inspecting in 12 months.

Read that entry in pieces. The distance (28.4 ft) tells a crew where to work. The material and diameter (cast iron, 4-inch) tell you what repair methods are possible. The code (RT) and severity (moderate) tell you how urgent it is. The description (30 percent of the opening, flow not blocked) explains why it is moderate rather than urgent.

What to do if the report is vague

If the report uses phrases like “some deterioration” or “possible issue” without a distance, a photo, or a severity rating, ask for a written clarification before you approve any work. You are entitled to a report you can actually use.

Judging Severity: Which Findings Need Immediate Repair

Not every finding is an emergency, and not every “urgent” label on a report is created equal. The most useful way to sort findings is to ask three questions about each one: **How bad is the defect itself? Knowing the signs of sewer line damage helps you interpret severe findings and decide when repair is urgent.

The three-question severity test

1. Defect severity. How much structural or flow capacity is gone?

2. Location. A defect under a driveway, sidewalk, or mature tree costs far more to reach than the same defect in open lawn.

3. Consequence of failure. A collapsed 4-inch lateral under a slab can back raw sewage into a basement.

A practical severity guide

How pipe material changes the call

Material matters more than most homeowners expect. Cast iron cracks widen over time as the wall graphitizes and thins, so a minor-looking crack may be a replacement candidate within a few years. Clay tile is brittle and joint movement is common; a small offset often worsens as soil shifts. Orangeburg can deform and collapse with little warning, so any deformation is urgent. PVC and ABS are more forgiving; a crack there is usually a localized impact or settlement issue.

How location changes the call

A defect under a mature tree, a driveway, or a slab is expensive to reach, so the threshold for repairing it early is lower. A defect in open lawn with no symptoms can often be monitored. A defect within 10 feet of the foundation deserves a closer look because a failure there can affect the structure, not just the drain.

The ambiguous middle: monitor vs. repair

Most real reports land in the middle, commonly a moderate finding with no current symptoms. The right move is usually a defined monitoring plan: clear the line if needed, re-inspect in 12 to 24 months, and watch for slow drains, gurgling, or sewage odor. Put the plan in writing so you know what would trigger a repair.

When to get a second opinion

Get a second inspection if the recommendation is a full replacement, if the report lacks photos or distance markers, or if the severity label does not match the description.

Sewer Camera Inspection Limitations and False Positives

Sewer camera inspection limitations are real, and honest technicians admit them. The camera shows the inside of the pipe, not the soil around it.

Common limits include:

• Heavy grease buildup can hide defects behind it
• The camera cannot measure structural weakness in the surrounding soil
• A pipe defect deep in standing water may be missed

This is why a good report pairs visual inspection with a camera locator and clear notes. If a diagnosis seems thin, ask for the footage.

What to Do After a Sewer Scope Inspection

What to do after a sewer scope inspection depends on what the report found. Here is the order we recommend:

1. Read the whole report, including severity notes
2. Watch the footage and match it to the photos
3. Ask questions about any finding you do not understand
4. Get the repair options in writing
5. Decide between clearing, repair, or lining

Minor blockage findings often mean a good cleaning and a maintenance plan. Structural findings mean planning a repair. See what trenchless sewer lining cost covers and how camera findings drive repair decisions.

Verify the Diagnosis Before You Approve Any Repair

Before you approve a big repair, verify the diagnosis. This protects you from paying for work you do not need.

Ask these questions:

• Can I see the inspection footage and inspection photos?
• Where exactly is the problem location on the report?
• Does the repair recommendation match the severity?

A trustworthy company shows you the evidence. If someone pushes a full replacement without sharing the video, slow down. Inspection findings should always back up the price.
