A CCTV drain inspection is a non-invasive method of examining the inside of your underground drain pipes using a small, waterproof camera. The camera is fed into the drain and transmits live video footage to a monitor, allowing a licensed plumber to see exactly what is happening inside the pipe without digging.
Adelaide homes with ageing clay pipes, established trees, and reactive clay soils benefit the most from CCTV inspections because the problems are hidden underground and impossible to diagnose from the surface. With nearly a decade of experience servicing homes across the Adelaide metropolitan area, Exceed Plumbing performs CCTV drain inspections across Adelaide to diagnose blockages, locate damage, and plan targeted repairs. This guide covers how the process works, when you need one, what it costs, what the report tells you, and why it saves money compared to guesswork.
How a CCTV Drain Inspection Works
A CCTV drain inspection gives you a direct, real-time view of the inside of your drain pipes. Instead of guessing where a problem might be or digging up your yard to find it, the camera shows the exact location and nature of the issue.
I have been running CCTV inspections across Adelaide for years, and the technology has transformed how we diagnose drain problems. What used to require hours of excavation and guesswork now takes under an hour in most cases. The camera does not lie. It shows tree roots, cracks, blockages, collapsed sections, and incorrect pipe falls with pinpoint accuracy.
Here is what the process looks like from start to finish, and what you can expect when a licensed plumber arrives at your property to carry out the inspection:
Access Point Identification
The plumber locates the best access point for the camera. This is usually an inspection opening, overflow relief gully, or cleanout point in your yard. In some cases, the camera can be inserted through an internal drain, such as a floor waste or toilet connection.
Camera Insertion and Navigation
A high-resolution waterproof camera mounted on a flexible rod or motorised crawler is fed into the drain. The plumber guides it through the pipe network, recording footage as it moves. The camera has built-in LED lighting and can navigate bends, junctions, and varying pipe diameters.
Real-Time Monitoring and Recording
The live footage is displayed on a monitor that the plumber and homeowner can view together. The entire inspection is recorded for review and reporting. The camera also tracks distance from the entry point, so the exact location of any issue can be measured and mapped.
Issue Identification
As the camera moves through the pipe, the plumber identifies and documents any problems found, including tree root intrusion, cracks and fractures, joint displacement, sediment buildup, pipe collapse, incorrect fall gradient, and foreign objects. Each issue is logged with its distance from the access point, making it easy to locate for repairs.
Report and Recommendations
After the inspection, the plumber provides a detailed report including the footage, a summary of findings, and recommended next steps. This report is yours to keep and is essential for insurance claims, property settlement negotiations, and planning future maintenance.
When Do You Need a CCTV Drain Inspection?
Not every drain problem requires a CCTV inspection, but there are clear situations where it is the most effective and cost-efficient first step. If any of these apply to your property, a CCTV inspection is the right call:
Recurring Drain Blockages
If the same drain blocks repeatedly despite being cleared each time, there is a structural issue inside the pipe. Tree roots regrowing through cracked joints, a collapsed section catching debris, or a pipe with incorrect fall are all causes that a CCTV inspection identifies in minutes. Without the camera, you are paying for repeated clearing without ever fixing the underlying problem.
Before Buying a Property
A pre-purchase CCTV drain inspection reveals the condition of underground drainage before you commit to buying. Cracked pipes, root-damaged sections, and ageing clay infrastructure can cost thousands to repair. In Adelaide, many homes built before the 1980s in suburbs like Norwood, Burnside, Goodwood, and Mitcham have original clay sewer pipes that are 50 to 70 years old. A CCTV inspection before settlement gives you negotiating power or a clear picture of future costs.
Slow Drains Across Multiple Fixtures
When the toilet, shower, and sinks all drain slowly at the same time, the blockage is in the main sewer line rather than an individual drain. A CCTV drain camera pinpoints exactly where and what the blockage is, so the plumber can fix it in one targeted visit rather than guessing.
After a Major Storm or Flooding
Heavy rain can shift underground pipes, wash soil into cracks, and accelerate tree root intrusion. If your drains behave differently after a storm, a CCTV inspection checks for damage before a minor shift becomes a major collapse.
Before or After Renovations
Renovations involving bathrooms, kitchens, or laundries often connect new plumbing to existing underground drains. A CCTV inspection before the renovation confirms the existing drains can handle the additional load. An inspection after the renovation verifies that new connections have been made correctly.
Persistent Sewer Smells
If you smell sewage in your yard or inside the house despite all traps being wet and functioning, a cracked or displaced pipe may be leaking sewer gas. The camera identifies exactly where the breach is.
Quick Reference: Do You Need a CCTV Inspection?
| Situation | CCTV Inspection Recommended? | Why |
| Same drain blocks repeatedly | Yes | Identifies structural cause |
| Buying a property | Yes | Reveals hidden pipe condition |
| Multiple drains slow at once | Yes | Locates main line blockage |
| After major storm or flooding | Yes | Checks for pipe movement or damage |
| Before or after renovation | Yes | Confirms drain capacity and connections |
| Persistent sewer smell | Yes | Locates cracked or displaced pipe |
| One-off minor blockage (hair, food) | Usually not | Surface blockage, clear with basic methods |
What a CCTV Drain Inspection Can Find
The camera reveals problems that are completely invisible from the surface. Here are the most common issues identified during CCTV drain inspections across Adelaide properties:
Tree Root Intrusion
Roots enter through cracked joints and grow inside the pipe, trapping waste and causing recurring blockages. Adelaide’s tree-lined suburbs like Prospect, Colonel Light Gardens, and Stirling are heavily affected. The camera shows exactly where roots have entered and how severe the growth is. For more on this issue, see our guide on tree roots in drain pipes.
Cracked, Fractured, or Broken Pipes
Ground movement from Adelaide’s reactive clay soils cracks pipes over time. The camera shows the type, location, and severity of each crack, helping the plumber determine whether the pipe can be relined or needs replacing.
Joint Displacement
Clay pipes were installed in short sections joined with cement mortar. Over 40 to 70 years, ground movement displaces these joints, creating gaps that let roots in and allow waste to escape into the surrounding soil. The camera measures the degree of displacement at each joint.
Pipe Collapse
In severe cases, ageing clay or earthenware pipes collapse entirely, blocking the drain completely. The camera shows the extent of the collapse and helps plan the excavation and replacement with modern PVC.
Incorrect Fall Gradient
If a pipe is installed without adequate fall (slope), water and waste do not flow properly, and sediment accumulates. This is a common issue in older Adelaide properties and in some newer developments where installation standards were not met. The camera confirms whether the fall is adequate or needs correction.
Sediment and Scale Buildup
Adelaide’s moderately hard water causes mineral scale to accumulate inside pipes over time. Combined with grease and soap residue, this narrows the internal diameter and restricts flow. The camera shows the extent of buildup and whether hydrojetting will restore full flow or whether the pipe needs further attention.

How Much Does a CCTV Drain Inspection Cost in Adelaide?
Cost is one of the most common questions homeowners ask, and the answer depends on the scope of the inspection and the complexity of the drain network:
Typical Adelaide Price Range
A standard residential CCTV drain inspection in Adelaide typically costs between $200 and $500. This includes the camera inspection, real-time viewing with the homeowner, and a written report with footage. More complex inspections involving longer pipe runs, multiple access points, or difficult-to-reach sections may cost more.
What Affects the Price
Several factors influence the final cost of a CCTV drain inspection, and understanding these helps you know what to expect when you receive a quote:
| Factor | Impact on Cost |
| Length of pipe to inspect | Longer runs take more time |
| Number of access points | Multiple entry points add complexity |
| Pipe condition (heavy blockage may need pre-clearing) | Hydrojetting before camera adds cost |
| Report detail level (basic vs comprehensive with footage) | Detailed reports with mapped footage cost more |
| Emergency vs scheduled | After-hours callouts attract higher rates |
Why It Saves Money
A CCTV inspection costs a fraction of the alternative. Without the camera, a plumber would need to excavate sections of pipe to find the problem, costing potentially thousands in digging, pipe replacement, and landscaping restoration. The camera eliminates guesswork and allows targeted repairs at the exact point of failure. It also prevents paying for repeated drain clearing when the real issue is structural.
At Exceed Plumbing, we provide upfront pricing for CCTV inspections before any work begins. No surprises.
CCTV Inspection vs Traditional Drain Diagnosis
Before CCTV technology became standard, plumbers diagnosed drain problems by feel, sound, and educated guesswork. Here is how the two approaches compare for Adelaide homeowners:
| Factor | CCTV Inspection | Traditional Methods |
| Accuracy | Pinpoints the exact location and cause | Approximate, based on experience |
| Excavation required | No (unless repair is needed) | Often, yes, to locate the problem |
| Time to diagnose | 30 to 60 minutes | Hours to days |
| Cost of diagnosis | $200 to $500 | Higher (includes excavation costs) |
| Visual evidence for the homeowner | Yes (footage and report) | No |
| Useful for insurance claims | Yes (documented evidence) | Limited |
| Useful for property purchases | Yes (pre-purchase report) | Not practical |
| Disruption to property | Minimal | Significant (digging, landscaping damage) |
The comparison is clear. CCTV inspection is faster, cheaper, less disruptive, and provides documented evidence. For Adelaide homes with ageing underground infrastructure, it is the standard approach.
What Happens After a CCTV Drain Inspection?
The inspection is the diagnosis. What comes next depends on what the camera finds, and a good plumber will walk you through the options based on the footage and report:
If the Drains Are Clear
If the inspection shows clean pipes with no cracks, roots, or structural issues, the plumber will confirm the drains are in good condition. This result is especially valuable for pre-purchase inspections, giving you confidence in the property.
If Blockages Are Found
Depending on the type and severity, the plumber may recommend hydrojet drain cleaning to clear the blockage. Hydrojetting uses high-pressure water to remove tree roots, grease, scale, and debris without damaging the pipe.
If Cracks or Joint Displacement Are Found
For pipes with structural damage that are otherwise intact, pipe relining creates a seamless new pipe inside the old one. This seals cracks, closes joint gaps, and prevents root re-entry. No excavation required. A quality line carries a warranty of 35 to 50 years.
If the Pipe Has Collapsed
A collapsed section requires pipe replacement. The CCTV footage shows the exact location and length of the collapse, allowing the plumber to plan a targeted excavation rather than digging up the entire pipe run.
In South Australia, all plumbing work must be performed by a licensed plumber under the Plumbers, Gas Fitters and Electricians Act 1995. A certificate of compliance (eCoC) must be issued within seven days, as outlined by the SA Office of the Technical Regulator.
Recently, the team and I attended a drainage callout for an Adelaide homeowner who needed their drain problem diagnosed and resolved quickly. Seth Coultas shared this feedback: “Very quick to come and fix our drainage problem. Friendly and clear communication about the cost before undertaking the work.” At Exceed Plumbing, upfront communication and fast diagnosis are how we approach every job.

Why CCTV Drain Inspections Matter More in Adelaide
Adelaide’s specific conditions make CCTV drain inspections more valuable here than in many other Australian cities, and understanding why helps you make informed decisions about your drainage maintenance:
Ageing Clay Pipes in Older Suburbs
Most Adelaide homes built before the 1980s have clay or earthenware sewer pipes with mortar joints every 300mm to 600mm. After 40 to 70 years, these joints crack, shift, and crumble. Suburbs like Magill, Blackwood, Modbury, and West Lakes are particularly affected. A CCTV inspection is the only way to see the condition of these pipes without digging them up.
Reactive Clay Soils Cause Ground Movement
Adelaide’s reactive clay soils expand when wet and contract when dry, causing constant ground movement that shifts and stresses underground pipes. This movement is the primary reason pipes crack, joints displace, and falls occur over time. Properties in the Adelaide Hills and eastern suburbs experience the most severe ground movement.
Established Tree Canopies
Adelaide’s mature trees are a defining feature of the city, but their root systems actively seek out moisture in underground pipes. A single CCTV inspection reveals whether roots have entered your drains, how severe the intrusion is, and which joints are compromised. This allows targeted treatment rather than blanket clearing.
SA Water Network Junction Issues
When a blockage sits at the junction between your private drainage and the SA Water sewer main, responsibility can be unclear. A CCTV inspection from your side documents whether the issue is on your property or in the SA Water network. SA Water advises homeowners to contact a licensed plumber to determine whether the blockage is private or public infrastructure.

Frequently Asked Questions
What is a CCTV drain inspection?
A CCTV drain inspection uses a small waterproof camera inserted into your drain pipes to capture live video footage of the interior. It identifies blockages, tree root intrusion, cracks, joint displacement, and pipe collapse without any excavation. The inspection typically takes 30 to 60 minutes for a standard residential property.
How much does a CCTV drain inspection cost in Adelaide?
A standard residential CCTV drain inspection in Adelaide typically costs between $200 and $500. The price depends on the length of pipe, number of access points, and whether pre-clearing is needed. Exceed Plumbing provides upfront pricing before any work begins.
Do I need a CCTV drain inspection before buying a house?
A pre-purchase CCTV inspection is strongly recommended, especially for Adelaide homes built before the 1980s that are likely to have ageing clay pipes. The inspection reveals hidden problems that a standard building inspection will not cover, giving you negotiating power or a clear picture of future repair costs.
What problems can a CCTV drain inspection find?
The most common issues found are tree root intrusion, cracked or fractured pipes, displaced joints, pipe collapse, incorrect fall gradient, and sediment or scale buildup. All of these are invisible from the surface and can only be diagnosed accurately with a camera.
How often should I get a CCTV drain inspection?
For homes with older clay pipes, established trees nearby, or a history of recurring blockages, a CCTV inspection every two to three years is recommended. For newer homes with PVC pipes and no history of drain issues, an inspection every five years or before major renovations is sufficient.
What happens after a CCTV drain inspection?
The plumber provides a detailed report with footage, findings, and recommendations. Depending on the results, next steps may include hydrojet cleaning to clear blockages, pipe relining to seal cracks and prevent root re-entry, or pipe replacement for collapsed sections. The report is also useful for insurance claims and property negotiations.
