Drains hide a lot. Pipes run underground, behind walls, and beneath floors, carrying water and waste away from homes and businesses. When something goes wrong, the signs are usually surface-level—slow drainage, foul smells, or toilets that keep blocking. Guessing at the cause can waste time and money.
CCTV drain inspections remove the guesswork. A small, high-resolution camera is sent into the pipe, recording everything it passes. The footage tells plumbers exactly what’s happening inside, from the smallest obstruction to a collapsed section of pipe. For property owners, it means clarity. No more wondering why blockages keep returning or what’s really causing the problem.
At Graham & Sons Plumbing, we’ve seen how powerful CCTV inspections are for both homeowners and businesses across Sydney. They save money, prevent repeated repairs, and give peace of mind by showing issues no one can see from the outside.
A CCTV drain inspection uses a purpose-built camera that feeds live footage back to the plumber. The camera is attached to a flexible rod, making it possible to push through bends, junctions, and long pipe runs.
The process looks straightforward on the surface, but the detail it captures makes it invaluable. The camera records:
For many property owners, this is the first time they get a clear view of their plumbing system. Instead of relying on guesswork or repeated plunging, the inspection shows what’s really blocking the way.
CCTV footage often reveals hidden blockages that homeowners struggle to clear themselves, similar to the situations we describe in our guide on how to unblock a toilet using different methods. Standard tools may work temporarily, but only a camera shows why a problem keeps returning.
The footage can be surprising. Problems that seemed simple often turn out to be far more complicated. Here are the most common findings:
Tree roots are naturally drawn to water and can break through tiny cracks in pipes. Once inside, they spread quickly, causing repeated blockages and structural damage. An inspection makes the intrusion visible in seconds.
Research in Australia shows that over 95% of pipe blockages handled by water utilities are caused by tree root intrusion. This highlights just how common the issue is in both residential and commercial settings.
One of the most common results is tree roots breaking into stormwater pipes, which often explains why a property experiences frequent flooding or drainage issues during heavy rain.
Pipes can shift due to ground movement, traffic above, or poor installation. Cracks then form, and entire sections may collapse. From the surface, this usually shows as a recurring blockage or leak. On camera, the collapsed area is obvious, giving the plumber the exact location for repair.
Grease build-up is a major issue in kitchens, especially in commercial settings. Over time, layers of fat harden and narrow the pipe. Objects like wipes, toys, or sanitary items also show up during inspections. In many homes, a stubborn blockage turns out to be something flushed that shouldn’t have been.
CCTV cameras also reveal when blocked toilets are caused by foreign items lodged deep in the line, far beyond the reach of a plunger or auger.
Pipes installed incorrectly or at the wrong angle can cause water to pool or flow back in the wrong direction. These problems often remain invisible without a camera inspection.
It’s common for inspections to trace repeated toilet problems back to deeper pipe issues. Many people assume the toilet is at fault, but the footage shows otherwise. A CCTV inspection can identify whether the problem sits within the fixture itself or further down the system. In some cases, what looks like a minor clog is actually a symptom of ageing infrastructure.
Many property owners see a camera inspection as an added cost. In practice, it often reduces spending and prevents recurring problems, particularly for those needing professional help with Blocked Drains in Sydney. The value comes from precision.
Key benefits at a glance:
| Benefit | Why It Matters | Example |
| Accurate diagnosis | No guesswork or unnecessary digging | Locating a cracked joint without pulling up half a driveway |
| Cost savings | Detects issues before they escalate | Identifying minor tree root intrusion before it crushes the pipe |
| Targeted repairs | Plumber knows exactly where to act | Marking the point of a blockage for efficient excavation |
| Peace of mind | Clear evidence of the problem | Homeowner sees the footage themselves and understands the repair plan |
An inspection can also influence decisions about fixtures. In some cases, the footage confirms that repeated blockages stem from pipe deterioration, making replacement of old systems more practical. It helps people decide whether it’s time to replace an ageing toilet or continue with repairs.
Not every slow-drain call for a camera, but there are clear signs that suggest it’s the right choice.
Situations that justify an inspection:
Homeowners often underestimate how serious hidden issues can be. In one Australian plumbing discussion forum, a user shared how they found a rock and then a large root ball deep in the sewer line. They had tried multiple surface fixes, but the problem persisted until a camera inspection exposed the real cause.
Some homeowners only realise the value after spending money on temporary fixes that don’t last. If plungers, chemicals, and basic tools keep failing, it’s a sign the issue runs deeper. That’s the stage where calling a professional plumber for persistent drain issues makes sense.
A client in the Inner West contacted us after dealing with a toilet that blocked almost weekly. Standard clearing methods worked for a short time, but the problem kept returning. The CCTV camera revealed a toy lodged in the line about three metres from the toilet. Traditional tools never reached it. Once removed, the household had no further blockages.
Once we removed the toy, the household had no further blockages. The owners told us how relieved they were to finally see the footage for themselves, as it confirmed the cause beyond doubt. From our side, it was a textbook example of how quickly an inspection can separate guesswork from fact.
Situations like this highlight the practical value of an inspection. It pinpoints the real cause rather than treating symptoms.
CCTV inspections are typically priced as part of a professional plumbing service. While costs vary, the average in Sydney ranges from $250 to $550, depending on pipe length and accessibility. Many customers view it as money well spent compared to ongoing call-outs for repeat blockages.
An inspection may also prevent costly structural work. Identifying a collapsed section early allows for a small, targeted excavation rather than a large-scale dig. In commercial properties, catching grease build-up in its early stages avoids closures due to blocked drains.
Seeing is believing. A plumber’s explanation carries weight, but video proof gives confidence. Footage shows the exact problem, whether it’s tree roots, a cracked joint, or a foreign object.
It also clarifies responsibility. For example, if a blockage is in a shared line between properties, footage provides evidence for council or neighbour discussions. In other cases, it can help landlords decide whether repairs fall under tenant misuse or general wear.
CCTV drain inspections give clarity that no other method can match. They expose the real cause of recurring blockages, highlight structural damage, and support accurate, targeted repairs. For Sydney property owners, it often means the difference between repeated plumbing bills and a single effective solution.
If you’ve experienced repeated blockages, unusual drain noises, or unexplained odours, booking a CCTV inspection may save time, money, and stress. Graham & Sons Plumbing carries out thorough inspections across Sydney, providing clear reports and reliable repair options.
