How CCTV Drain Inspections Find Tree Roots and Broken Pipes
A blocked drain is easy to notice. What is actually causing it is not. You can clear a slow sink or a gurgling toilet a dozen times and still have no idea whether the real problem is a wad of wet wipes or a tree root that has worked its way through a joint two metres underground. That is where a CCTV drain inspection comes in. Instead of guessing, our Newcastle plumbers feed a waterproof camera straight into your pipes and watch the problem on screen in real time.
Here is what that inspection actually shows us, and how it tells the difference between a root intrusion and a broken pipe before we ever pick up a shovel.
What a CCTV Drain Inspection Actually Shows You
We feed a specialised, water resistant camera into your drain line and push it as far as it needs to go, often 60 metres or more from the access point. A radio transmitter (called a sonde) sits just behind the camera head, so we can pinpoint the exact depth and location of whatever we find from above ground, without digging test holes to look for it.

The footage is recorded as we go, so you are not taking our word for it. You get to see exactly what is happening inside your own pipes, whether that is a clean, clear line or a section that needs attention.
How Tree Roots Get Into Your Pipes
Tree roots do not punch through solid pipe. They find their way in through a weakness that is already there. On camera, root intrusion shows up unmistakably: a mass of roots filling part or all of the pipe, often at the exact spot where a joint or crack lets water seep out.
1. A Hairline Crack From Ground Movement
Common in older earthenware or PVC lines, a fine crack from shifting ground is enough for roots to find the moisture and nutrients inside a drain line. A fine root that finds a way in thickens over time and spreads.
2. A Joint That Has Shifted Out of Alignment
Pipe joints move slightly over time as the ground around them settles. Once a joint is even fractionally out of alignment, it opens a path roots can exploit.
3. A Gap Left by a Poorly Sealed Repair or Connection
Not every root problem starts with age. A connection that was never sealed properly can let roots in almost immediately.

Root intrusion is also the most common reason a drain keeps blocking up even after we clear it. If you have had the same section of drain jetted more than once in a short space of time, roots regrowing through the same weak point are usually why.
What a Broken or Collapsed Pipe Looks Like on Camera
Not every problem is roots. The camera also picks up structural damage that would otherwise stay hidden. These issues look different to root intrusion on screen: instead of a tangle of roots filling the pipe, you see a visible gap, an offset joint, or the pipe itself sagging or crushed out of shape.
1. Cracked or Fractured Sections
Common in old earthenware, copper or PVC pipe, a cracked section lets water and soil move in and out of the line, weakening it further over time.
2. Separated or Shifted Joints
A joint that has pulled apart or moved out of line creates a gap where waste catches and water escapes into the surrounding ground.
3. Sagged Sections That Pool Water
Ground movement can leave a low point in the pipe where water and waste pool instead of draining away, rather than a single visible break.
4. Fully Collapsed Pipe
Usually the end result of long-term ground movement or age, a collapsed length of pipe blocks the line completely and cannot simply be jetted clear.
Knowing which one you are dealing with matters, because a collapsed pipe cannot simply be jetted clear the way a blockage can. It needs to be repaired.
Worried About a Slow or Recurring Drain?
Slow drainage, gurgling sounds, and unpleasant odours can be early signs of a developing blockage. An inspection can help identify the problem before it causes an overflow or property damage.
Why Guessing Costs You More Than Inspecting
Without a camera, the usual approach to a recurring blocked drain is to clear it and hope it does not come back. When it does come back, next time you might reach for a bigger snake, or start talking about digging up the yard on a hunch.
A CCTV inspection skips the guesswork. We can tell you, with the video to back it up, whether you are dealing with:
- A one-off blockage that a good clean will fix
- Root intrusion that will keep returning until the entry point is repaired
- A structural problem that needs excavation and repair, not just clearing
That means any digging we do is targeted to the exact spot the footage shows, rather than an educated guess at where the problem might be.
What Happens After the Inspection
Once we know what we are dealing with, the next step depends on what the camera found:
- Blockage only: we clear it with high pressure water jetting, which strips grease, roots and built-up sludge from the pipe walls rather than just punching a hole through the middle.
- Root intrusion at a joint or crack: we jet the roots out, then repair the specific joint or section they are getting in through, so they cannot simply regrow back into the same spot. If the leak has affected other fixtures, our leak detection team can trace it further before any repair begins.
- Broken or collapsed pipe: our pipe repair team excavates and repairs or replaces the damaged section, keeping the dig as small and targeted as the footage allows.
Where it makes sense, we run the camera through again after the repair to confirm the line is clear and running properly, so you are not left wondering if it actually worked.
Signs You Might Need a CCTV Drain Inspection
- The same drain has blocked more than once in the last few months
- Water drains slowly even straight after clearing
- Gurgling sounds from drains that are not currently blocked
- Damp or unusually green, lush patches in the yard above where pipes run
- You are buying an older Newcastle home and want to know what condition the drains are actually in before you sign
Signs tree roots may be affecting a drain
Common indicators include:
- Blockages that repeatedly return after clearing
- Several household fixtures draining slowly at once
- Gurgling sounds from toilets or floor wastes
- Unpleasant smells around outdoor drains
- Wastewater rising through a shower or floor drain
- A blockage that becomes worse after periods of rain
Removing the roots may restore flow temporarily, but the damaged section of pipe may still need repair to prevent regrowth.
Frequently Asked Questions
Can tree roots really get through a solid pipe?
Not through solid, intact pipe. They get in through an existing crack, a shifted joint or a poorly sealed connection, then thicken once they are inside. The pipe has to already have a weak point.
Will jetting alone fix a drain with root intrusion?
Jetting clears the roots that are currently blocking the line, but if the entry point (the crack or joint) is not repaired, roots will typically find their way back in. A camera inspection tells us whether a repair is needed alongside the clear.
How far can the camera actually see into my drains?
Our CCTV equipment can travel 60 metres or more into a line, which covers the vast majority of residential and commercial drain runs in one pass.
Do I need to dig up my yard to find the problem?
No. The camera and sonde locator let us pinpoint the exact depth and position of a problem from above ground, so any digging that is needed is targeted to that spot rather than a guess.
