A camera inspection can be a little high in price, however, consider the older days before camera's, we would just give an estimate to replace all of the drain pipes because a diagnosis was an educate guess, no one really new how bad the problem is, just by looking at the end of the sewer cable to see what it pulled back, roots? sand? misc. dibris?, now with a camera there is a tool which can save a customer big money and a plumber lots of time!
