How to Interpret Drain Camera Inspection Results
Getting a drain camera inspection is the first step toward solving drainage problems. However, understanding the footage and report can be confusing if you don’t know what to look for.
In this guide, we explain the most common findings from drain camera inspections in Greater Vancouver and what they actually mean for your system.
Common Findings and What They Mean
-
Tree Roots Intruding into the Pipe
Appearance: Stringy or branch-like growth inside the pipe.
Meaning: Roots have entered through joints or small cracks. This is extremely common in Greater Vancouver due to our many mature trees.
Severity: Moderate to High — Roots will continue growing and eventually block the pipe completely if not addressed.
-
Grease and Sludge Buildup
Appearance: Dark, sticky coating on the bottom or walls of the pipe.
Meaning: Years of kitchen waste and soap have accumulated. This is the most common cause of slow drains.
Severity: Low to Moderate — Usually fixed well with hydro jetting.
-
Bellied or Sagging Pipe
Appearance: A section of pipe that dips downward (looks like a belly).
Meaning: The pipe has settled, causing waste and debris to collect in the low spot.
Severity: High — This often leads to recurring clogs and may require pipe replacement.
-
Cracks or Separated Joints
Appearance: Visible lines or gaps in the pipe wall or at connections.
Meaning: The pipe is damaged or old. Water and roots can easily enter through these gaps.
Severity: Moderate to High — Depending on how many and how large the cracks are.
-
Collapsed or Crushed Pipe
Appearance: The pipe is flattened, broken, or completely blocked.
Meaning: The pipe has failed structurally.
Severity: Very High — Usually requires excavation and replacement.
-
Heavy Silt or Clay Buildup
Appearance: Mud or clay filling the bottom of the pipe.
Meaning: Common in properties with poor filter fabric or heavy clay soil.
Severity: Moderate — Often requires hydro jetting and possible system upgrades.
What the Colors and Image Quality Mean
- Clear, bright image — Good pipe condition
- Dark or foggy image — Heavy buildup or water in the line
- Red or flashing indicators — The camera is highlighting a problem area
