We insert a small, remotely controlled cameras into the pipe and propel it along the pipeline until it reaches the blockage or the issues, whatever it may be.
The camera provides a clear image of the entirety of the pipe. It transmits the image back to our equipment and we are able to accurately diagnose problems and provide effective solutions based on what the camera sees.
This method of pipe inspection saves us from experimenting and trying multiple methods to see which one might work. We are able to find the correct solution the first time.
