The first step in finding out if your sewer pipes can be fixed, either repaired or replaced, with the trenchless method, the causative situation underlying the problem needs to be known. When a sewer line starts having problems, there often will be indicative signs, although sometimes these will not be noticed or will be overlooked. These signs can often visibly show what the problem is with the sewer line, although not always. Because of developments in camera technology, video can be taken of the interiors of sewer and other lines instead of visual checks, which require pits to be dug along a sewer line.
If you are sure that your sewer lines are in a specific location because you have had a technician use a sonde in the past, then it will be easy to determine if the problem is located in a position that can be reached between the two pits required for trenchless sewer repair methods. Many homeowners do not know exactly where their lines are located at and must rely on luck when having an excavation done to uncover broken sewer pipes.
The second step is knowing where those sewer lines are located at and where, if any, joints are located at. Not knowing where a sewer line is located at often seems to push homeowners toward choosing trenchless methods because many assume it is always a straight line. This is often true, but if there are bends in the line, another pit must be dug at each joint so that one section of pipe can be joined to the other pipe that needs to be inserted at a different, but now correct, angle. A camera inspection will show any bends or joints that must be worked around. One or two are to be expected and do not normally preclude trenchless repairs. It is the location of those joints that is important to know.
If the sewer lines is found on a camera inspection to only be clogged by household waste, be it from the bathroom or the kitchen, or by organic matter such as tree roots, another trenchless method can be sufficient to remedy the problem. Hydrojetting can clear out tree roots, even thicker ones, and remove greasy clogs full of hair and other debris. Sediment from breaks in the line is also removed with hydrojetting.
After hydrojetting is completed, drains are completely free of any blockages, and drains inside the house or business will flow freely again. This is an excellent time to have a sewer pipe lined before there are additional problems. Doing so reduces digging required to complete both tasks, and eliminates the time tree roots have to regrow back into the cracks. Liners repel tree roots, so after a pipe is lined, tree roots are no longer an issue.
After a camera inspection has been completed, the reason for existing problems with a sewer line will most likely be discovered. Some issues can be repaired without excavation. Other issues, unfortunately, cannot. Completely collapsed lines need to be excavated in their entirety and are not candidates for trenchless work. If trenchless repair work can be done, it is often the least-expensive, -time-consuming, -interruptive, and -destructive, while being the more direct, exact, and targeted option.
