What a drain camera is
A drain camera is a small lens with lights, fitted to the end of a long, flexible rod. It is fed into the pipe through an inspection opening, a toilet outlet or a cut-in access point. A screen shows the picture as it moves along. Many systems can also record video and stills.
CCTV stands for closed-circuit television. In plumbing it simply means a camera inside the pipe.
What it can show
- Roots entering at joints
- Cracks, broken sections and collapsed pipe
- Offset joints, where two lengths no longer line up
- A belly, which is a low spot where water and waste sit
- Build-up of fat, scale or debris
- Where the pipe changes material, or where another pipe joins
Some systems can also find the depth and position of the camera head above ground, which helps when a repair needs digging.
When it is useful in the Mountains
Older cottages with clay pipes and big trees nearby are the clearest case. A camera can tell the difference between a one-off blockage and a pipe that is failing.
- A drain keeps blocking in the same place
- You are buying an older house and want to know about the sewer
- You are planning to build over or near a sewer line
- You want to check a repair before the trench is closed
- You need a record for an insurance claim
A recorded inspection can also help when a council or Sydney Water asks where a fault lies.
When you may not need one
A slow kitchen sink or a toilet blocked by paper rarely needs a camera. The plumber can clear it, check it flows, and move on. Ask whether it's needed for your job, and ask what it would tell you that you do not already know.
Not every plumber carries camera gear, and not every job allows access. Ask when you call whether the visit includes a camera, or whether it would be arranged separately.
What to expect on the day
The plumber needs a way into the pipe. That may be an inspection opening, a removed toilet or a cleaning eye. In older homes, there may not be one, and creating one is a separate step.
The pipe is usually cleared first so the lens can see. The camera then travels the line while the plumber watches the screen. You can ask to see it, and to be told in plain words what each finding means.
Ask for the video or stills and a short written note on what was found. Keep it with your house records.
What it costs
The price depends on the length of pipe, the access and whether the line needs clearing first. Ask for a quote before work starts. Ask whether a report and a recording are included.
Questions to ask
- Will you give me the recording and a written summary?
- Does the price include clearing the pipe first?
- If you find a problem, what are the repair choices?
- Is the whole line viewable, or only part of it?

Can a camera find a blockage?
Yes. It can show what the blockage is made of and where it sits, which helps the plumber choose the right fix.
Will an inspection damage my pipes?
The camera is made to move through pipes gently. Old or fragile pipe can still be hurt by any tool, so tell the plumber what you know about it.
Is a camera inspection worth it before buying a house?
For an older home with big trees, it can be. It shows the pipe condition before you sign.
Can I watch the inspection?
You can ask. Most plumbers are happy to show you the screen and explain what you are seeing.
