How Does a CCTV Drain Inspection Camera Work?

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

There are a number of CCTV drain inspection cameras that are available. The biggest difference between each model is the size and width of the pipes they are able to inspect and the total distance they can travel (which is based on the cable’s length).

Every drain camera is capable of taking photos and recording 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 which is designed to travel deep underground into stormwater pipes and sewers. The plumber 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 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.

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.

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.

Step 5 – The Report: After a drain inspection, many plumbers follow up with a handwritten report. The owner of the property is provided with this report which outlines everything found from the camera and any recommendations needed to repair the issue.
