One of the most common plumbing problems you will run in to is blockage in the drain or sewer line. Until recently, there was no sure way of determining the cause of the problem except an expensive excavation of the pipes. Now with the advances in technology, the problem can be found a lot easier, with a simple inspection of the sewer line using a camera. If you're experiencing backing up toilet water, water back up into your tub or shower when you flush, or water coming up from your faucets, it's probably time for a video inspection to determine the blockage.
