CCTV Drain Inspection: When Do You Need One?
A CCTV drain inspection is the only way to see exactly what is happening inside your pipes. Here are the six situations where it is worth every dollar — and what to expect when the camera goes in.
A CCTV drain inspection uses a waterproof camera on a flexible rod to inspect the inside of your pipes in real time. You need one if you have recurring blockages, own a home with original pipes from before 2000, are buying or selling a property, have large trees near your sewer line, are planning construction, or hear gurgling sounds from your drains. The inspection costs $200-350 and pays for itself by preventing expensive emergency repairs.
- • Recurring blockages = time for a CCTV inspection to find the root cause.
- • Homes built before 2000 with original clay or cast-iron pipes need a baseline check.
- • Pre-purchase inspections are standard practice — do not buy a property with hidden pipe problems.
- • Large trees within 3 metres of your sewer line mean annual inspections are smart.
- • Construction or landscaping near drains? Inspect before you dig.
- • Early warning signs (slow drains, gurgling) are the best time to inspect — before a complete blockage.
6 reasons to book a CCTV drain inspection
Across Mosman, Manly, Dee Why, and Brookvale, we recommend CCTV inspections for these six situations:
You have recurring blockages in the same location
If your drains keep blocking despite clearing, there is an underlying issue — tree roots, a pipe crack, a collapsed section, or a protruding pipe joint. CCTV reveals exactly what is causing the recurrence.
Your home is 20+ years old with original pipes
Clay and cast-iron pipes installed before 2000 have a limited lifespan. Over decades, joints loosen, pipes crack from ground movement, and internal corrosion narrows the pipe diameter. A baseline CCTV inspection tells you the condition of your pipes before a problem occurs.
You are buying or selling a property
A pre-purchase CCTV drain inspection is becoming standard practice on the Northern Beaches. It reveals whether the sewer and stormwater pipes are in good condition, or whether you are inheriting a $5,000-15,000 pipe repair. Sellers can use a clean inspection as a selling point.
Large trees are near your sewer line
If you have mature trees within 3 metres of your sewer line, root intrusion is a matter of when, not if. An annual or bi-annual CCTV inspection catches root growth early, before it causes a complete blockage.
You are planning landscaping or construction
Building a deck, patio, extension, or pool over or near existing drains? A CCTV inspection before construction starts prevents accidental damage and confirms the pipes can handle any changes in load or flow.
Slow drainage or gurgling sounds
The early warning signs of a partial blockage — slow drains, gurgling noises, or unpleasant odours — are exactly when a CCTV inspection is most valuable. Catching the problem early means a simpler, cheaper fix.
What happens during a CCTV inspection
- Access. The plumber finds a cleanout access point — usually a capped pipe in your yard, garage, or where the toilet connects to the floor.
- Camera feed. A waterproof camera on a flexible push rod is fed into the pipe. The feed appears on a monitor in real time.
- Inspection. The camera travels the full length of the pipe, recording the interior condition. The rod measures the distance to any defects.
- Report. You receive a video recording and a written report noting pipe condition, defects (cracks, roots, blockages, collapsed sections), and their locations.
When to call a plumber
You do not need a blockage to justify a CCTV inspection. In fact, the best time to inspect is before a problem occurs. But if you have any of the following, book one now:
Drains that block every 6-12 months in the same location.
A toilet that gurgles when the shower is running or vice versa.
A home built before 1990 where the pipes have never been inspected.
You are considering pipe relining and need to confirm the pipe is suitable.
Unpleasant smells from drains that persist after cleaning.
You want peace of mind before spending money on bathroom renovations or landscaping.
Book a CCTV drain inspection and we will send a plumber with a high-resolution camera to inspect your drains. You will see the footage yourself and get a written report with our findings.
Northern Beaches considerations
CCTV inspections are especially valuable on the Northern Beaches because of our combination of mature trees, ageing infrastructure, and reactive clay soils. Suburbs like Mosman, Balgowlah, and Seaforth have many original clay pipes from the 1950s-70s that are now approaching the end of their useful life. A CCTV inspection is the only way to know their true condition.
In coastal areas like Manly and Dee Why, sandy soils can cause pipes to shift or sag over time, creating low points where sediment accumulates. These sags are invisible from the surface and only detectable with a camera.
If you are buying a property on the Northern Beaches, a pre-purchase CCTV inspection is one of the best investments you can make. A $300 inspection could save you $8,000-15,000 in pipe repairs that the vendor never disclosed. Contact our team to book.
Frequently asked questions
Does a CCTV drain inspection damage my pipes?
No. The camera head is smaller than the pipe diameter — typically 20-50 mm — and mounted on a flexible push rod. It cannot damage sound pipes. In severely collapsed or blocked pipes, the plumber will stop the camera and clear the obstruction first before proceeding with the inspection.
How long does a CCTV drain inspection take?
A standard residential inspection takes 30-60 minutes for an average sewer line of 10-20 metres. The plumber feeds the camera through a cleanout access point or through a removed toilet. You watch the footage in real-time on a monitor.
Will I get a copy of the CCTV footage?
Yes. We provide a full video recording and a written report with marked locations of any defects. This is useful for insurance claims, pre-purchase disclosures, or planning repairs.
How much does a CCTV drain inspection cost on the Northern Beaches?
A standard CCTV drain inspection costs $200-350 depending on access and pipe length. This is a fraction of the cost of an emergency blockage repair and gives you a complete picture of your pipe health.
