What a CCTV Drain Survey Actually Shows You
Most people book a drain survey after something has already gone wrong. That is understandable, but it means the camera is usually confirming a problem rather than finding one early, when it is cheaper to fix.
What the camera is looking for
A survey runs a small waterproof camera through the pipe run and records the whole length. Three things matter on the footage: displaced joints where sections have moved apart, root ingress where a tree has found a hairline crack, and standing water that should have drained away. Any of the three explains a drain that keeps backing up after it has been cleared.
Why the second survey matters more than the first
Clearing a blockage and declaring the job done is the common shortcut. A second pass with the camera after jetting is what proves the pipe is genuinely clear rather than merely flowing again. Ask for the recording; a contractor confident in the work will hand it over without being pushed.
What it costs to be wrong
Repeated call-outs for the same blockage cost more over a year than one survey that finds the displaced joint causing them. If you have paid twice for the same drain, you are already paying for the survey - just not receiving one.
