A CCTV drain inspection is one of the most useful tools in modern plumbing. Instead of guessing what’s wrong with your drains or digging up your yard to find out, a small camera goes inside the pipe and shows exactly what’s happening. Here’s when you need one and what to expect.

How Does It Work?

A CCTV drain inspection involves inserting a small, waterproof camera attached to a flexible cable into your drain or sewer pipe. The camera sends real-time video to a monitor, allowing the plumber to see the condition of the pipe from the inside.

The camera can identify:

• Blockages — What’s causing the blockage and exactly where it is
• Tree root intrusion — Roots growing through pipe joints or cracks
• Cracks and fractures — Damaged sections that could lead to leaks
• Pipe collapse — Sections where the pipe has failed completely
• Joint displacement — Pipes that have shifted or separated
• Corrosion and buildup — Scale, rust, and sediment narrowing the pipe
• Cross-connections — Incorrect plumbing connections

When Should You Get a CCTV Drain Inspection?

Recurring Blockages

If the same drain blocks repeatedly, there’s an underlying cause that a plunger or drain snake won’t fix permanently. A camera inspection reveals the root cause — whether it’s tree roots, a collapsed pipe, or a design fault.

Before Buying a Property

A pre-purchase drain inspection can save you from inheriting expensive sewer problems. Older Melbourne homes are particularly prone to cracked clay pipes, root intrusion, and deteriorated drainage. It’s a small investment that can reveal thousands in hidden problems.

Slow Drains Throughout the House

When multiple drains are slow, the problem is likely in the main sewer line rather than individual fixtures. A camera inspection quickly identifies the location and cause.

After a Sewer Backup

If sewage has backed up into your home, you need to know why. A CCTV inspection after clearing the blockage reveals whether the cause is likely to happen again and what permanent fix is needed.

Sewer Smell

Persistent sewer odours inside or outside your home can indicate cracked pipes, failed joints, or other drainage defects that a camera inspection will find.

Renovations or Extensions

Before building over or near your sewer line, a camera inspection confirms the pipe’s location, depth, and condition. This prevents accidental damage during construction and ensures you’re not building over a pipe that’s about to fail.

Older Homes

If your Melbourne home is over 30 years old and the drains have never been inspected, it’s worth checking their condition. Clay and cast iron pipes deteriorate with age, and knowing their state helps you plan for maintenance or replacement.

What Happens During the Inspection?

1. Access point — The plumber accesses the drain through an inspection opening, drain grate, or cleanout point
2. Camera insertion — The camera is fed into the pipe and pushed through the system
3. Live viewing — The plumber watches the video feed in real time, noting any problems and their location
4. Distance tracking — The equipment tracks how far the camera has travelled, so problems can be precisely located
5. Recording — The inspection is recorded so you can see the footage and keep it for your records
6. Report — You receive a summary of findings with recommendations

The whole process usually takes 30-60 minutes depending on the size of the system.

What Can’t a CCTV Inspection Do?

It’s important to know the limitations:

• It can’t inspect pipes that are completely blocked until the blockage is cleared first
• Very small diameter pipes (under 40mm) may not accommodate the camera
• It shows the pipe condition but can’t predict exactly when a pipe will fail
• It can’t inspect pressurised water supply pipes (only gravity drainage)

Benefits of Regular Drain Inspections

Even if you’re not experiencing problems, periodic CCTV inspections can:

• Detect developing issues before they become emergencies
• Track tree root growth so you can manage it proactively
• Provide evidence for insurance claims if problems occur
• Give peace of mind about the condition of your drainage
