CCTV Drain Inspection Cameras: How They Work & The Benefits

Drain inspection cameras (also known as sewer cameras or pipe inspection cameras) have changed the plumbing industry forever, helping plumbers know everything happening inside pipes and drains that are underground without having to inspect them physically. This helps determine the cause of the blocked drain so they can recommend an affordable and accurate solution.

How do drain inspection cameras work?

CCTV Drain Inspection cameras work by sending a camera down the drain or pipe and transmitting footage back to a monitor on the surface. This footage can be used to identify the precise location of any blockages and other issues that may need attention, such as cracks, leaks, or corroded pipes.

Different types of CCTV Drain Inspection Cameras

Several CCTV drain inspection cameras are available. The most significant difference between each model is the size and width of the pipes they can inspect and the total distance they can travel (based on the cable’s length).

Every drain camera can take photos and record videos inside of the pipes. Then this information is displayed on a monitor where the plumber can watch and observe inside the pipe in real-time.

These advanced cameras are quite small and get attached to a flexible cable that is designed to travel deep underground into stormwater pipes and sewers. Our plumbers can see every part of the lines and pipes, including the corners, due to the improved manoeuvrability of the cable. This is the standard and most basic method for sewer-line camera inspections.

The benefits of CCTV Drain Inspection Cameras

CCTV Drain Inspection Cameras offer many benefits for plumbers, including:

  • Improved accuracy and efficiency when diagnosing pipe blockages
  • Reduced need for excavation and manual inspection
  • Increased safety for workers, as there is no longer a need to enter into potentially hazardous areas
  • Lower overall costs, as plumbers can now diagnose and fix problems without having to send someone down the drain or pipe.

The step by step process for a CCTV drain inspection for your home

Step 1 – The Entry Point

After arriving at your property, the operator of the CCTV drain inspection camera will determine which entry point of your home would provide the easiest and most effective access to the problematic pipe or drain. Then they will find the entry point by using stormwater or sewer plans that are provided by the homeowner, or by physically examining the property.

Step 2 – The Insertion

Next, the operator will put the camera in the opening of the drain or pipe and feed it slowly as the camera records and displays on a screen. Since the operator will be able to see in real-time, they are able to use the camera to fully view the pipe as it travels down the line. The inspection of the pipe will take place as the camera is slowly fed down the line. Any obstructions, cracks, or leaks in the pipe will be captured on video and photographed for further review. Once the inspection is complete, the operator will then recover the camera back

Step 3 – The Examination

By carefully analysing the recorded footage through the monitor, the operator is able to identify all of the problems within the pipeline. They can also determine the source of the blocked drain, then diagnose any faults in the pipes and see if any previous attempts at fixing the blocked drain have worked. With this knowledge, plumbers can provide solutions that are both effective and affordable.

Step 4 – The Recommendation

After analysing the video, the CCTV drain camera operator can recommend a targeted and affordable solution that will fix the root of the problem. By using drain cameras, it simply removes any guessing out of blocked drains, which in return lets the plumber offer a calculated solution. This also saves the homeowner from any potential further damage that may be caused if the initial problem is not fixed.

Step 5 – The Report

After a drain inspection, many plumbers follow up with a handwritten report. The owner of the property is provided with a detailed report which outlines everything found from the camera and any recommendations needed to repair the issue.  Drainage camera reports are a great way of providing the customer with peace of mind and can act as proof that the job was completed to a high standard.
