Do I Need a Video Inspection for My Seattle Sewer Line Repair?

When something goes wrong with your sewer line, the last thing you want is guesswork. Sewer problems happen underground, out of sight — and without the right tools, it’s nearly impossible to know what’s actually causing the issue.

That’s where a professional sewer camera inspection comes in.

At Bob Oates Plumbing, Sewer & Rooter, we use high-resolution camera technology to take the uncertainty out of sewer repair. In a matter of minutes, we can see exactly what’s happening inside your pipes and recommend the right solution — whether that’s a simple cleaning or a full repair.

For Seattle homeowners, who are responsible for repairing the entire side sewer line up to where it joins the city’s main line — this step isn’t just helpful. It’s essential.

Do You Need a Sewer Camera Inspection?

In most cases, the answer is yes — especially if you’re noticing warning signs.

You should schedule a sewer inspection if you’re experiencing:

• Recurring clogs or slow drains

• Gurgling sounds from toilets or fixtures

• Sewer odors inside or outside your home

• Wet spots or unusually green patches in your yard

• A recent sewer backup or overflow

• An older home (typically 20+ years old)

Even if the issue seems minor, these symptoms often point to deeper problems in the line — like tree root intrusion, pipe damage, or buildup that won’t resolve on its own.

A video camera inspection allows us to diagnose the problem at the source, instead of treating symptoms repeatedly.

How Often Should You Inspect Your Sewer Line?

For most homes in the Seattle area, we recommend:

• A baseline inspection around the 20-year mark

• Follow-up inspections every 2–3 years

• More frequent checks if:

  • You have large trees near your sewer line

  • Your home has older clay or cast iron pipes

  • Previous issues like roots or cracks have been found

Regular inspections are one of the most effective ways to prevent major sewer failures and avoid unexpected repair costs.

They’re also highly recommended when buying a home, especially in older Seattle neighborhoods where sewer lines may already be compromised.

What a Sewer Camera Inspection Actually Shows

A sewer camera inspection is a simple, non-invasive process. We insert a waterproof, high-definition camera into your sewer line — typically through an existing cleanout — and guide it all the way to the city connection.

The live video feed gives us a clear, real-time view of your entire side sewer.

This allows us to identify issues such as:

• Tree root invasion

• Grease, debris, or scale buildup

• Cracks, corrosion, or fractures

• Sewer bellies (low spots where water collects)

• Offset or misaligned pipe joints

• Collapsed or severely damaged sections

Using advanced locator equipment, we can also pinpoint the exact location and depth of any problem areas. That means no unnecessary digging — and no surprises.

After the inspection, we walk you through what we found and provide clear, straightforward recommendations.

Why Sewer Inspections Matter in Seattle

Seattle’s environment creates unique challenges for underground sewer lines.

Heavy Rain and Shifting Soil

Frequent rainfall saturates the ground, which can cause soil movement. Over time, this can shift pipes out of alignment, create cracks, or even lead to partial collapses.

Tree Root Intrusion

Seattle’s mature trees have extensive root systems that naturally seek moisture. (We’ve written an entire post on how to tackle roots in pipes.) Sewer lines are a prime target, and even small cracks can quickly turn into major root invasions.

Full Side Sewer Responsibility

Unlike many cities, Seattle homeowners are responsible for the entire side sewer — even beyond the property line and under sidewalks or streets. That makes proper diagnosis especially important before any repair work begins.

A camera inspection helps ensure you’re making informed decisions, not expensive guesses. And Bob Oates is a registered side sewer contractor with over three decades of experience serving the local community.

From Inspection to Repair: What Happens Next

One of the biggest advantages of a sewer camera inspection is that it sets the stage for the right repair approach.

Depending on what we find, solutions may include:

• Drain cleaning or hydro jetting to remove buildup and restore flow

• Spot repairs for isolated damage

• Trenchless sewer repair, such as pipe lining or pipe bursting

• Full sewer line replacement in cases of severe structural failure

In many cases, trenchless methods are affordable, no-dig solutions that allow us to repair or replace your sewer line without tearing up your yard, driveway, or landscaping.

That’s why every trenchless project starts with a thorough inspection — it ensures the solution is both effective and efficient.
