How Does a Drain Camera Inspection Work?

A drain camera inspection takes the guesswork out of diagnosing pipe problems — instead of assuming what’s wrong based on symptoms, you actually see the cause.

The process

A waterproof camera mounted on a flexible cable is fed into the drain or sewer line through an existing access point, such as a cleanout or the toilet outlet. As the camera moves through the pipe, it streams a live video feed that shows the interior condition in real time.

What it reveals

• The exact location and cause of a blockage — root intrusion, grease build-up, a foreign object, or a structural issue
• Cracked, collapsed, or misaligned pipe sections
• Root intrusion at pipe joints, a common issue in older properties with mature trees nearby
• The general condition of ageing pipework, useful before buying a property or planning a renovation

Why this matters for repairs

Without a camera, diagnosing a recurring blockage usually means educated guesswork — and sometimes unnecessary digging in the wrong spot. A camera inspection pinpoints the exact location and nature of the problem, so any excavation or repair work is targeted rather than exploratory. This generally makes the repair faster and less disruptive.

When it’s worth doing

Recurring blockages that keep coming back after clearing, unexplained slow drainage, before purchasing a property with an older sewer line, or simply confirming a previous repair actually worked before backfilling any excavation. It’s a diagnostic step that often saves money by avoiding guesswork-based repairs.
