Did you know that over 77% of Australian households experience blocked or damaged drainsevery year, often without realising it until disaster strikes?
Underground plumbing problems don’t announce themselves until it’s too late. From sneaky tree root invasions to cracked or collapsed pipes, many issues lie hidden until major damage unfolds. Traditionally, pinpointing the source meant guesswork, digging, and often tearing up driveways or gardens, only to discover a minor fix was needed.
Thankfully, the plumbing industry has moved on from the shovel. Non-invasive diagnostics are now leading the charge, with CCTV technology paving the way for smarter, cleaner, and far more accurate inspections.
These drain cameras venture where plumbers can’t, offering a live view deep inside your pipes—without breaking ground. It’s a game-changer for detecting issues early and ensuring repairs, like relining, are precise and cost-effective.
Let’s explore how this clever technology works behind the scenes.
What is CCTV Pipe Inspection?
CCTV stands for Closed-Circuit Television. In plumbing, this refers to high-resolution cameras attached to flexible rods or robotic crawlers. These are inserted into pipes to capture live video footage of the interior condition of drains and sewer lines. The footage is viewed in real-time, allowing plumbers to inspect pipes without digging or damaging surrounding areas.
This method is used in both residential and commercial settings. It’s designed to identify common issues, such as blockages, fractures, corrosion, and joints that have shifted out of place. Because the inspection is visual and immediate, it removes the guesswork and reveals the full extent of any damage.
The video footage provides a reliable basis for making informed repair decisions, especially when planning for pipe relining. It also supports long-term plumbing care, as plumbers can record and reference the system’s condition over time.
This approach catches problems early, saving time and money in the long run. For good reason, CCTV pipe inspection is now a key part of modern plumbing diagnostics.
Why Traditional Methods Fall Short
Before camera technology became available, diagnosing pipe problems often involved a fair bit of guesswork. Plumbers relied on symptoms like slow drains or surface leaks to locate issues, which meant trial and error was common. The only way to be sure was to dig—sometimes across driveways, lawns or even through concrete slabs.
This process wasn’t just disruptive. It was expensive, time-consuming and often inaccurate. Property owners could spend thousands uncovering large sections of pipe, only to discover the issue was minor or in the wrong place. Small cracks, root intrusions or offset joints were easily missed, leading to repairs that failed to solve the real problem.
One example involved a homeowner who paid for full excavation work only to learn the cause was a single misaligned joint. Had a CCTV inspection been carried out first, trenchless relining could have fixed the issue in a day.
How CCTV Inspections Support Pipe Relining
Pipe relining isn’t guesswork. It relies on clear, detailed information, starting with a proper CCTV inspection.
1. Seeing the Inside Clearly
Using a CCTV plumbing camera, plumbers can examine the full interior of a pipe system in real-time. This inside view is essential for relining preparation, giving accurate information on the pipe’s condition before any work begins. Issues like cracks, rust, or root intrusion are identified early, so nothing is missed.
2. Planning the Relining Job
CCTV footage helps map the pipe layout, including length, diameter, and access points. This information guides how the epoxy liner will be inserted and cured. It also shows if anything is blocking the pipe, such as debris, grease, or roots, which need clearing before the relining can start.
3. Precision and Practical Repairs
Some pipes are too damaged to reline, such as those with full collapses or severe misalignment. The camera footage confirms if the pipe is suitable or if replacement is a better option. This prevents unnecessary work and allows for a practical repair plan tailored to the situation.
4. Better Long-Term Outcomes
With a clear plan, the epoxy liner can be placed precisely. That means fewer disruptions, better flow, and longer-lasting results. Using CCTV as a non-invasive drain repair tool ensures the job is done right from the start, saving time and money in the long run.
Benefits of CCTV Pipe Inspections for Homeowners and Businesses
CCTV pipe inspections offer a smart and reliable way to manage plumbing issues before they spiral out of control. This modern approach to drain diagnostics benefits both homeowners and business operators.
- No digging is required. Plumbers can assess underground pipes without disturbing driveways, lawns, or floors, which protects landscaping and reduces cleanup time.
- Faster repairs and planning: With clear footage, plumbers can diagnose problems quickly and prepare an efficient repair or relining plan without delay.
- Reduced repair costs: Avoiding exploratory digging saves labour and equipment costs and lowers the chance of unnecessary or incorrect repairs.
- Less disruption to daily life or business operations: Properties can remain functional throughout inspection, making it ideal for busy households and commercial spaces.
- Early detection of hidden issues: Problems like hairline cracks, corrosion or minor tree root intrusion are caught early, preventing costly emergencies later.
- Recorded evidence for future use: Footage can be saved to support insurance claims or to assist with future maintenance schedules.
- Peace of mind through clear visuals: Property owners can see exactly what’s happening in their pipes and make informed choices based on real evidence—not assumptions.
This modern solution adds confidence to every step of the plumbing process.
Step-by-Step Look at the CCTV Inspection Process
Understanding how a CCTV drain inspection works can help relieve the stress of plumbing problems. The process is quick and noninvasive and usually takes less than an hour for most homes.
Step 1: Drain cleaning
If the pipe is blocked or filled with debris, a quick clean using water jets may be needed. This clears the path so the camera can move freely.
Step 2: Camera insertion
A high-resolution CCTV camera is gently fed into the pipe through an existing access point, like a drain opening or inspection cap.
Step 3: Live footage begins
The camera travels through the pipe, capturing clear video of the interior. Plumbers watch the footage in real-time to assess the condition.
Step 4: Problem identification
Any issues—like cracks, roots, or misaligned joints—are logged, and the footage is marked with notes and timestamps for reference.
Step 5: Review and recommendations
The plumber explains the findings once the inspection is complete and recommends relining repairs or further cleaning.
There’s no digging, guessing, or mess—just instant clarity. As one of our licensed technicians put it, “With CCTV, we know exactly what we’re dealing with before lifting a tool.”
Common Issues Found with CCTV Inspections
CCTV drain camera inspections uncover a wide range of hidden problems that often go unnoticed until serious damage occurs. These issues are usually buried deep within the pipe system and can’t be seen without the right tools.
- Tree root intrusion: Roots from nearby trees or shrubs can grow into tiny cracks or joints in the pipes, causing blockages and breaking the pipe from the inside out.
- Cracked or burst pipes: Shifting soil, age, and pressure can cause pipes to crack, leading to leaks, water loss and eventual collapse.
- Misaligned joints: Pipe sections can shift out of place, disrupting flow and trapping waste or debris, which can lead to blocked drains.
- Build-up of scale or grease: Over time, fat, oil and mineral deposits can stick to the pipe walls, narrowing the internal space and slowing water flow.
- Collapsed or deteriorated pipe sections: Severe wear or ground movement can cause pipes to cave in, which may require trenchless pipe repair or replacement.
These problems are rarely visible until advanced—CCTV inspections help catch them early before they become emergencies.
Why CCTV is Essential Before Any Pipe Relining Job
CCTV inspections are a vital step before starting any pipe relining project. They provide a clear, inside look at the condition of the pipes, allowing plumbers to confirm exactly where relining is needed and avoid working on sections that are beyond repair or perfectly fine.
Accurate diagnostics save time, prevent unnecessary labour, and reduce the risk of costly mistakes. Every pipe system is different, so having visual confirmation ensures the repair is fully tailored to the specific problem. The footage also helps determine the best relining materials and methods for the job.
A practical benefit is the ability to mark footage with notes and timestamps. This makes it easy for clients to understand what’s being shown and where the issues are. It also helps with planning and quoting, making the process more transparent from start to finish.
