# CCTV drain camera (plumbing)

CCTV drain cameras, also known as sewer cameras or pipe inspection cameras, are a line of waterproof, high definition cameras that have become a widely popular technology in the plumbing profession. These cameras are advanced diagnostic tools that allow plumbers to execute plumbing inspections, called CCTV Drain Surveys with heightened accuracy.
These cameras can vary; the main difference being the size of the pipe the camera ca inspect. The total distance they can travel within the pipeline is also a common difference between models.

## Purpose

CCTV drain cameras are used to uncover any damages or obstructions within the plumbing system. They provide a non-invasive and efficient way to assess the internal condition of drainage pipes and sewer systems, ensuring that issues are accurately identified and addressed without the need for disruptive excavation or guesswork.
These advanced cameras are equipped with high-resolution imaging and flexible cables that allow them to navigate through various pipe sizes and shapes, capturing clear, real-time footage of the inside of the drainage network. As modern-day technology, they are specifically designed for surveying and assessing the working condition of water pipes and sewer lines, making them an invaluable tool for both residential and commercial applications.
In the plumbing world, CCTV drain cameras are commonly used to detect and locate potential problems, such as debris buildups, collapsed pipe sections, root infestations, and pipe offsets. By providing a clear visual of the interior of the drainage system, these cameras help professionals diagnose issues accurately and plan effective solutions. This level of precision eliminates the need for trial-and-error methods, reducing repair time and cost for property owners.
Moreover, CCTV inspections are often conducted as part of routine maintenance to prevent serious drainage problems from developing. Early identification of minor defects, such as hairline cracks or corrosion, allows plumbers to recommend proactive repairs, extending the lifespan of the drainage system. Consequently, CCTV drain cameras contribute significantly to maintaining the overall health and functionality of plumbing networks.

## Usage

The camera, attached to a long, flexible cable, is fed through an access point on the property, such as a drain cover or cleanout. It is then carefully maneuvered through the pipes until it reaches the point of damage or obstruction. As the camera moves through the plumbing system, the captured footage is transmitted directly to a monitor or screen, giving the plumber a real-time view of the affected area. This live feed allows the professional to inspect the condition of the pipework, identify issues, and determine the exact location of any problem spots, such as blockages, cracks, or root intrusions.
The camera can also be used in tandem with a plumber’s snake (also known as a drain auger). After the camera has pinpointed the position of a blocking object, such as a buildup of debris or a foreign object, the plumber’s snake can be fed into the same access point. The snake's flexible design allows it to navigate bends and tight spaces within the pipe, where it can then be used to break up or remove the blockage. This combination of tools ensures a highly efficient process, minimizing disruption and avoiding unnecessary excavation or pipe removal.
Additionally, CCTV drain cameras are often paired with hydro-jetting equipment. Once the camera has identified the extent of the obstruction, high-pressure water jets can be used to thoroughly clean the pipe interior, effectively removing any stubborn residues or buildup. This step is especially useful for clearing out grease, scale, or other accumulations that may restrict water flow.
Through the use of these modern technologies, plumbers can achieve accurate diagnoses and perform targeted repairs, reducing the need for extensive digging or structural disruptions. The combination of CCTV drain cameras, plumber’s snakes, and hydro-jetting provides an integrated solution to maintaining and repairing plumbing systems efficiently and cost-effectively.
