Professional Drain Inspections in Seattle, WA, and Surrounding Areas

Fast answers. Clear diagnostics. No guesswork.

If you’re noticing foul odors, recurring backups, or slow-moving sinks and showers, a professional drain inspection is the quickest way to understand what’s happening inside your pipes — before a small issue becomes a costly repair.

At Bob Oates Plumbing, Sewer & Rooter, our licensed technicians use high-resolution drain cameras to pinpoint the exact cause of your plumbing symptoms. With over 30 years of experience serving the Greater Seattle area, we deliver accurate diagnostics, upfront guidance, and long-lasting solutions you can trust.

Why Drain Inspections Matter

Plumbing issues often start small and out of sight. A drain inspection:

• Reveals hidden clogs, cracks, corrosion, and root intrusion

• Confirms whether simple cleaning will resolve the problem

• Helps prevent future backups or water damage

• Gives you clear footage and recommendations — no guesswork

Before we clean or repair any line, we inspect it first. That’s how we ensure the right fix the first time, every time.

How Our Drain Inspection Process Works

1. Locate the Problem

Using a waterproof, high-definition camera, our technicians inspect your drains from the nearest cleanout or P-trap. This allows us to see:

• Grease buildup or scale

• Tree roots invading the line

• Misaligned joints or bellies

• Cracked, corroded, or collapsed sections

We can also pinpoint the depth and exact location of any issue using locator tools.

2. Clean the Line (If Needed)

If we find a blockage or buildup, we’ll clear the line using either:

• Professional snaking — effective for most household clogs

• Hydro jetting — high-pressure water jetting that cleans and restores the pipe's full diameter

Every cleaning is followed by a second camera inspection to verify that the line is fully clear.

3. Recommend Repairs (When Necessary)

If camera footage reveals cracks or structural damage, our team may recommend a trenchless repair solution such as CIPP lining.

This no-dig method installs a new epoxy-coated liner inside the existing pipe, creating a smooth, durable interior surface with minimal disruption to your home.

Our technicians arrive in fully equipped Bob Oates service vehicles to handle sewer, drain, and plumbing issues.

When to Schedule a Drain Inspection

A quick camera check can save you time and money if you notice:
