What Can a CCTV Drain Survey Actually Show?

What can a CCTV drain survey actually reveal about your drainage system?

A CCTV drain survey offers a live view inside your drainage system, helping you spot blockages, structural damage, and early signs of wear before they escalate. By sending a drain inspection camera through underground pipework, professionals can assess internal conditions quickly and with minimal disruption. This method is widely used by responsive teams like 24hrs Drainage Ltd, who serve homes and businesses across the South East.

How CCTV Drain Surveys Work and What They Look For

How It Works

These surveys use a waterproof camera on a flexible rod. The setup is fed into a drain through an inspection chamber and moved through the pipework, sending real-time footage to a technician for review.

The Technology Behind It

The typical equipment includes:

  • A flexible rod to guide the camera through bends

  • A camera with integrated lighting for clear visuals

  • A monitor displaying live footage

  • Reporting software to capture and mark issues

At 24hrs Drainage Ltd’s CCTV survey service, engineers pair this technology with jetting and descaling to maintain and repair systems efficiently. The internal pipe view it provides is crucial for diagnosing underground pipe defects without digging.

Pro Tip: Always request the recorded survey footage—it gives you evidence if repairs or insurance claims are needed later.

The Survey Process

Once inserted, the camera sends footage as it moves through the pipes. Technicians monitor the feed, noting any damage or obstructions. The recorded footage is reviewed and turned into a detailed report.

This process enables a visual pipe survey that clearly identifies issues like root ingress, fatbergs, or displaced joints. 

What Issues Can a Drain Camera Actually Show?

Visible Problems Cameras Commonly Catch

Drain cameras pick up many internal issues that are otherwise hidden:

Structural Faults

  • Cracked pipe walls

  • Sections that have collapsed

  • Joints that have shifted

  • Internal corrosion or scale buildup

Intrusions and Obstructions

  • Roots breaking through the pipe

  • Grease or fat causing blockages

  • Sediment buildup slowing flow

  • Entry holes left by pests

These common drain issues may not become obvious until serious disruption occurs. Many customers rely on 24hrs Drainage Ltd for blocked drain investigations to catch problems early and avoid repeat visits. A clear sewer scope finding from a camera pipe check brings clarity and peace of mind for property owners.

High quality footage provides clear insight, helping customers act quickly and make well informed decisions.

Because not everything is visible, drainage experts often uses tools like sonar and drain pressure testing to verify concerns and deliver a full diagnosis. Their specialist interpretation helps ensure a more reliable inspection.

Pro Tip: Use a drain camera before buying a home—it can reveal costly hidden defects not seen during standard surveys.

When Is a Drain Camera Not Enough?

Complementary Methods

If footage alone is not enough, other tools add clarity:

  • Dye testing helps locate leaks and trace flows

  • Sonar profiling gives insight into depth and pipe condition

  • Pressure testing finds leaks through pressure loss detection

When to Combine Methods

  • When foul smells are present but no damage is seen

  • If damp areas appear near drains

  • When problems continue despite a clear camera report

24hrs Drainage Ltd often recommends combining methods to ensure every possible issue is checked. These advanced pipe diagnostics are especially useful for hidden leak tracking and non visual diagnostics.
