what is the analysis of drainage system?

Answer 1

An analysis of any system, lets you know how viable the system is. If there are obstructions in the pipes, or undersized mains, for example. Usually a camera is required to assess the whole system, and the inspector will make you a VCR tape of the filming of the interior of your drainage system. It will show any breaks, roots, or cave-ins. It is a useful tool, in order for you to make an informed decision, about future work.
