5 Reasons for CCTV Camera Inspection before Relining a Pipe


Sewer and pipelines require routine checks to make sure that they are functional and in good condition. Structural damage in any part of a pipe can cause the whole plumbing system to be ineffective. Blockage, deterioration, calcification and breakage is always a risk that, even though unavoidable, can be monitored and put under control in its earlier stages. In many cases, inspections using CCTV cameras are commissioned in order to thoroughly inspect sewer lines. Being one of the most efficient means of pipe inspection, plumbers use this method in pipe relining. Here are the top 5 reasons why they do that:

1. An efficient way to check the pipeline condition.

With this technological advancement, pipe and sewer inspection has never been easier. CCTV cameras record footages that are accurate and detailed. You see exactly what is going on inside the sewer pipes and all you have to do is insert a camera-ridden stick inside the entry point of the pipe you want to inspect. There are options, however on what type of camera you would like to use.

  • Pipe Inspection Gauge (PIG) Camera

This camera is attached to a cleaning gauge. Along with LEDs, it records actual footage and sends the feed to the operator interface through cables. With is swivelling head, PIG inspects sewers and lines without interrupting product flow.

  • Crawler Camera

Crawlers are drone cameras which enable plumbers or inspectors to stay inside the mobile control station while operating them through the sewage pipe.

  • Push Camera

Push cameras are very fragile devices which can be used for comprehensive monitoring of main lines and lateral pipes. This camera type can fit through pipes with the diameter of 6 inches.

2. An accurate basis for pipe maintenance decision.

Structural pipe damage can render the pipeline useless when if the problem remains untended for a long time. By using CCTV camera inspections, you check the of the pipe with multiple perspectives and a clean visual. By knowing the problems, a plumber can then decide the best course of action to do.

3. Flexible technology for a thorough inspection.

With its rotating and swivelling head, a CCTV camera can be manipulated to direct the footage to different corners of the pipe leaving no stone unturned. Most crawler drones can carry up to three cameras for maximum perspective while some cameras can tilt 90 to 360 degrees to allow the inspector to see the whole interior of a pipe. Some also feature additional scanning options to fully optimise the photos taken from inside the pipe.

4. Cost-effective means.

This non-destructive technique is highly used by plumbing companies and other individuals because it does not cause damage to property and does not require things to be removed or lawns be demolished.

5. Safe.

No matter how many precautionary measures you take or how serious you implement them, sewage and passageways are still potentially hazardous. With small pipes, entry is not even an option while in bigger and more industrialised ones, toxic fumes and chemical excretes can be a probable presence of unsuspicious pipes and these will cause health problems to plumbers who are tasked to fix them.
