What a Sewer Camera Inspection Shows — and When You Need One

01 How it works

A high-resolution waterproof camera travels through the sewer line while a locator above ground maps its exact position and depth. The result: you see the inside of the pipe in real time, and any problem gets a precise address — not a guess.

02 What the camera catches

Typical findings in San Gabriel Valley homes:

• Root intrusion at pipe joints — the classic cause of recurring backups near mature trees
• Bellies (sags) where waste and water pool and re-clog
• Cracked, offset, or collapsed sections
• Grease and scale narrowing the line
• Construction debris or foreign objects

03 When an inspection saves real money

Before buying a home (a failed lateral is a five-figure surprise). Before repeating a third drain-cleaning call on the same line — recurring clogs usually mean a structural cause. Before approving anyone's excavation quote: precise location and depth turn a 'dig up the yard' estimate into a targeted repair. And after a big cleaning job, to verify the line is actually clear.

04 Seeing is the standard

All Systems Pros shows you the footage — not just a verdict. Customers on our public Yelp profile describe exactly that experience: the camera in the line, the roots on the screen, and options explained with clear, upfront pricing before each step. That's how a diagnosis should work.
