CCTV Drain Survey – Advantages and Disadvantages



In the realm of modern plumbing diagnostics, CCTV drain surveys have emerged as a powerful tool, offering a detailed and efficient way to inspect the hidden intricacies of drainage systems. In this blog post, we’ll delve into what a CCTV drain survey entails, exploring its advantages and addressing a couple of potential drawbacks.

What is a CCTV Drain Survey?

A CCTV drain survey involves the use of specialized cameras to inspect the interior of drainage pipes and sewer lines. These high-tech cameras are attached to flexible cables, allowing them to navigate through the twists and turns of the plumbing system. The real-time footage captured by the cameras is then analyzed to identify issues such as blockages, leaks, or structural damage.

Advantages of CCTV Drain Survey

Precision and Accuracy:

  • One key benefit of CCTV drain surveys lies in their knack for delivering precise and accurate diagnostics. Equipped with high-resolution cameras, these surveys can capture detailed images, enabling plumbers, especially those specializing in Drain Unblocking Whangarei, to identify issues with pinpoint accuracy.

Time and Cost Efficiency:

  • CCTV drain surveys save both time and money compared to traditional methods of pipe inspection. They eliminate the need for extensive excavation to locate and diagnose problems, reducing labor costs and minimizing disruption to the property.

Preventive Maintenance:

  • Conducting regular CCTV drain surveys can help detect potential issues before they escalate into major problems. Identifying and addressing minor concerns early on can prevent costly repairs and extensive damage to the drainage system.

Non-Invasive Inspection:

  • Unlike traditional methods that often require digging up large areas to access pipes, CCTV drain surveys are non-invasive. This minimizes disruption to landscapes, driveways, and other structures on the property.

Comprehensive Documentation:

  • The recorded footage from CCTV drain surveys serves as comprehensive documentation of the current state of the drainage system. This documentation can be valuable for insurance claims, property assessments, and future maintenance planning.

Increased Safety:

  • CCTV drain surveys contribute to increased safety for both plumbers and property owners. By providing a clear view of potential hazards within the drainage system, such as structural damage or blockages, preventive measures can be taken to avoid accidents during maintenance or repairs.

Disadvantages of CCTV Drain Survey

Equipment Cost:

  • The initial investment in CCTV drain survey equipment can be relatively high. Smaller plumbing businesses may find it challenging to afford the advanced cameras and related technology, potentially limiting access to this diagnostic method.

Limited to Visual Inspection:

  • While CCTV drain surveys offer a detailed visual inspection, they do not provide information on the composition or chemical makeup of blockages or deposits within the pipes. In some cases, additional tests or methods may be needed for a more comprehensive analysis.


CCTV drain surveys have revolutionized the way plumbing issues are diagnosed and addressed. The advantages, including precision, efficiency, and preventive maintenance, outweigh the disadvantages, making CCTV drain surveys a valuable tool in maintaining the health of drainage systems. Despite some limitations, the technology continues to play a crucial role in ensuring the longevity and functionality of plumbing infrastructures.
