Got a sewer problem and have no idea what it is or where to dig? A relatively low-cost sewer video inspection just might help.
In years past, dig points were educated guesswork. Now, with sewer video cameras and locating equipment, it is a simple matter of calling for a sewer video inspection and locating the block.
Pipeline video inspection is a form of telepresence used to visually inspect the interiors of pipelines. A common application is to determine the condition of small diameter sewer lines and household connection pipes.
It is a process where you call in a plumbing company to run a video line through your waste pipes.
The video might extend down your branch lines (the pipes that lead from bathtubs and faucets to the house’s sewer line) or down the house’s sewer line (the larger pipe that leads from the house to the municipal sewer line on the street). At the end of the line is a camera that lets you see the line in close-up and real-time detail.
Roots from trees and vegetation may work into the joins between segments and can be forceful enough to break open a larger opening in terra cotta or corroded cast iron or PVC pipe. Eventually a root ball will form that will impede the flow and this may be cleaned out by a cutter mechanism and subsequently can be dug up, cut out and repaired.
With modern video equipment the interior of the pipe may be inspected – this is a form of non-destructive testing. A small diameter collector pipe will typically have a cleanout access at the far end and will be several hundred feet long, terminating at a manhole.
