A CCTV drain inspection sends a pan-and-tilt drain camera through your sewer or stormwater line to find what a plunger, a snake or a guess never will. The operator needs a physical opening to start from, runs the camera the length of the line, takes a sonde depth reading on any section holding water, and photographs every crack, root intrusion point and ponding section along the way. You should finish with a written report and images, not just a verbal summary at the front door.
The part most people are not warned about is access. If your property has no inspection opening, the camera has to enter somewhere, and that somewhere is usually a toilet pan or a downpipe. That work is quoted separately, and it can cost more than the inspection itself.
Key takeaways
- A CCTV drain inspection needs a physical entry point. No inspection opening means removing a toilet pan or opening a downpipe, and that access work is a separate line on the quote.
- A small camera head will usually pass a toilet pan. A larger head will not, and no camera head passes a shower grate because there is a trap directly beneath it.
- The written report is the product. Photographs of each fault, annotated with entry point and approximate location, are what you use for a warranty claim, an insurance claim or a repair quote.
- Foundation cracking, pre-purchase due diligence and pre-jetting condition checks are the three reasons most inspections get booked.
- Jetting a drain without a camera is spending money to stay uninformed, particularly on the ageing vitrified clay lines under pre-1980s Brisbane suburbs.
What actually happens during a CCTV drain inspection?
The operator locates an entry point, feeds a pan-and-tilt camera head into the line, and drives it along the pipe while watching the feed. Pan-and-tilt matters here because a fixed-lens drain camera looks straight ahead only. A camera that turns can look up into a junction, sit on a crack and rotate around it, and tell you whether root hair is entering at a single hairline fracture or through a failed joint.
Where water is sitting in the pipe, the operator drops a sonde reading. That gives depth and position at surface level, which is how you work out whether the line has lost fall or whether a section has dropped. A pipe holding water is not automatically a broken pipe. Without the depth reading, you cannot tell the difference.
On a residential CCTV sewer inspection, the run is short. On a commercial site or a strata block, it can take most of the morning, because there are more branches, more inspection points, and more junctions where waste collects without ever showing up as a symptom at a fixture.
Why does the plumber need to remove my toilet to get the camera in?
Because the drain camera has to go somewhere, and the options are limited.
The clean route is a proper inspection opening. If the property has one and it is accessible, the CCTV drain inspection starts and finishes there with no disruption. Plenty of older SEQ homes either never had one installed or have had one buried under a deck, a concrete path or forty years of garden bed.
When there is no opening, the toilet pan becomes the fallback. A smaller camera head will generally negotiate the bend in a pan. A larger head will not, which is why two operators quoting the same job can give you very different access costs depending on the gear on their truck.
Shower grates get suggested constantly, and they do not work. There is a trap directly under or shortly after the grate, and the outlet itself is small, with AS/NZS 3500 setting a 40mm minimum on shower drains. A camera head is not passing either obstacle.
For a CCTV stormwater inspection, downpipes are the usual entry. Square Zincalume downpipes can often be slid apart to create an opening and reassembled afterwards. A better build has an inspection point where the downpipe meets the stormwater PVC. Where neither is available, drilling an access hole and sealing it with a rubber gasket afterwards is cheaper than a full removal and reinstatement.
One honest caveat. If you genuinely want every branch of the drainage system looked at, then removing and reinstating toilets and downpipes is not padding. It is the only way to get a camera into those runs. Scope drives the cost, and a quote covering the whole system will always sit above a quote covering the one line you are worried about.
Worth knowing before you agree to a pan removal: the short run between the toilet and the main line rarely holds the fault people are hunting for. That length blocks because of what gets flushed down it. It does not usually crack.
How much is a CCTV drain inspection, and what changes the price?
There is no single CCTV drain inspection cost, because the inspection and the access are two different jobs. What moves the number:
- Whether you have an inspection opening. Existing and accessible is the cheapest scenario by a wide margin.
- How many lines you want covered. One suspect run is a different job to a full CCTV drain survey of sewer and stormwater across the property.
- Whether access work needs reinstating. A toilet pan removed and reset with a new seal costs more than a downpipe slid apart and pushed back together.
- Whether the line is currently blocked. A blocked drain often needs clearing before the camera can see anything, which changes the sequence and the scope.
- Whether you need a formal written report. A verbal walkthrough and a documented report with annotated images are not the same deliverable.
At SEQ Blocked Drains, the drain camera inspection cost is confirmed before we start, and where the inspection leads to a pipe relining job, the inspection cost comes off the final bill. Call for a quote on your specific property rather than working from a figure you found on a forum, because the forum figure almost certainly did not include access.
What should the report include?
This is where cheap CCTV drain inspections separate themselves from useful ones.
Nobody needs a recording of the entire drain. What you need is each fault captured and identified: every infiltration point, every crack, every ponding section, photographed and annotated with the entry point used and the approximate location along the run. Those images get written up and sent through with the invoice.
That documentation carries weight well beyond the day of the inspection. A photographed and annotated fault report is what a builder’s warranty claim, an insurance assessor or a QBCC claim will actually accept. A homeowner telling an insurer the pipe looked cracked on a screen is not evidence. A dated report with images and depth readings is.
Also ask whether a static water pressure test is included. It takes about ten minutes with a reusable gauge, and many drainage specialists will run it while on site as part of the job rather than billing it separately. If a quote lists it as a distinct line item, that is a fair question to ask.
One more thing to confirm before booking: the equipment. Inspections do get abandoned mid-job when budget gear fails, and a refund does not give you back the morning you took off work. Equipment quality is part of what you are paying for on any drainage camera inspection.
Should you run a CCTV pipe inspection before jetting, or after?
Both, on most jobs, and drainage specialists genuinely disagree about the sequence.
The case for camera first is condition assessment. Old vitrified clay and concrete lines that are already cracked or corroded can be pushed past their limit by high-pressure water. Sending 4000 PSI into a compromised pipe risks turning a repairable fracture into a collapse. A camera first also tells you whether the line needs jetting at all, and it protects both parties, because nobody is arguing afterwards about whether the jetter caused the damage.
There is a second argument for going in first. No symptoms at the fixtures does not mean no partial blockage. Junctions catch grease, waste and foreign objects while the drain still runs. Jet first and camera afterwards, and you have cleared the evidence: the line looks clean, and the reason it blocked stays unknown.
The counter-argument is practical. In a fully blocked line, you cannot see anything but muck. Some operators let the line drain, camera in to position the jetting nozzle accurately, clear it, then camera again to inspect the joints and inspection openings properly.
Both positions are right about different moments in the job. Before is for condition assessment. After is for verification of the clear and for finding root intrusion at the joints. A blocked line usually justifies both, and a recurring blockage always does.
What actually turns up in SEQ drains?
Roots are the headline, and species matters. Fine root hair entering a hairline crack at a clay pipe junction behaves differently to a mature fig or camphor laurel root mass that has split a joint open. The first is a relining candidate. The second usually needs robotic cutting before anything else happens.
Then there is the construction damage nobody knew about. Electrical conduit driven straight through a stormwater line during a build. A star picket left through a sewer since construction, causing intermittent blockages for a decade while every clear worked temporarily. Manufacturer date stamps on the offending material can often be read off the camera footage, which is how you date the works and identify who was on site.
Across pre-1980s Brisbane suburbs the common pattern is earthenware or vitrified clay with rubber-ring or mortar joints that have moved. Across Logan and Ipswich, reactive soils add ground movement to the same equation. Neither is a defect you find by clearing the blockage and hoping.
Why foundation cracking sends people to a drainage specialist
More CCTV drain inspections get booked off the back of a building inspector’s or structural engineer’s advice than most homeowners expect.
Water escaping a hairline crack does not stay in the pipe trench. It soaks into the clay sitting around the pipe. Reactive soil takes that water on and swells with it, then dries back out over summer and pulls away, and where that happens under one part of a footing rather than evenly across the whole slab, the structure above starts following the movement. Homeowners tend to notice it as cracking above a door frame. Some watch it open and close with the seasons for a couple of years before anyone thinks to look underground for a cause.
None of it shows up at a fixture. The drain runs fine the entire time it is leaking, so there is nothing to diagnose from the surface. A camera is the only way in.
Strata and commercial: jetting on a schedule without a camera
Preventative jetting is common in strata and matters more as a building ages. Where it goes wrong is when jetting is scheduled annually, and CCTV is refused before or after.
The pattern looks like this. Two hours of jetting is carried out. The report back says a large amount of debris was removed. More jetting gets booked on the same basis. Nobody has looked at the pipe, so the debris stays unexplained. Grease off a ground-floor tenancy behaves nothing like root hair at a single failed joint, and neither looks like a dropped section of line sitting full of waste, which will keep generating debris no matter how often it gets jetted. Meanwhile, a stain appears around the inspection point.
Repeat jetting without a CCTV pipeline inspection buys a clear line for a few months and no information at all. One camera run tells a body corporate whether they are managing a maintenance issue or funding an annual workaround for a defect that needs repair.
FAQs
A single line on a residential property usually takes under an hour once access is sorted. A full property survey covering sewer and stormwater, or a strata block with multiple branches, can take several hours. Access work is the variable, not the camera run.
Someone has to let us into the yard, and into the bathroom if a pan is coming up. Past that, no. Though if the problem comes and goes, being there helps. Describing what the drain does at 11 pm on a wet night is worth more to the operator than what it does at 9 am on a dry one.
No. The head is small, flexible, and puts nothing against the pipe wall on its way through. Jetting is the part of drainage work that breaks pipes, and old clay is what it breaks. Look first, jet second, on anything pre-1980s.
Yes, for the pipe side of it. The camera finds the crack or the open joint letting water out, and the sonde puts a depth and a position on it so the spot can be marked at the surface. How much water has gone into the ground already, and over how long, is a question for whoever is assessing the slab.
Terminology mostly, though a survey generally implies the full drainage system and a formal written report rather than one suspect line. Confirm the scope in writing before the job, because that is where quotes diverge.
It is worth doing on any pre-1980s property, particularly one with mature trees near the sewer line. Building and pest inspections do not cover the drainage system below ground, and a failed sewer line is not a cheap discovery to make after settlement.
Yes. A CCTV stormwater inspection runs through downpipes, pits and stormwater lines, and it is the relevant inspection where a pit overflows in a summer downpour or water pools against a footing after rain.
Book a CCTV drain inspection
Most of these jobs start the same way: a drain that blocks again a few months after the last clear. The rest come from engineers chasing slab movement, or from buyers wanting the line looked at before settlement on an older place with big trees over it. SEQ Blocked Drains runs pan-and-tilt CCTV across Brisbane, Ipswich, Logan and the Gold Coast. Cost is confirmed before we start, and the annotated images come through with the report.
