What method can be used to televise a sewer line through flooded low spots?

Using a high velocity cleaner to push water clear of dips in the sewer line is an effective method for televising a sewer line in areas that are flooded. This approach allows for the clearance of standing water, which can obstruct visibility during the inspection process. By utilizing a high velocity cleaner, the water can be displaced, creating a clearer pathway for the camera to travel through, enabling effective inspection of the sewer line condition.

This method is advantageous because it avoids the need for more invasive alternatives such as removing pipes completely or installing additional pumps, both of which can be time-consuming and costly. Additionally, while sonar technology might provide some data on the system's condition, it would not yield the same level of detail as a direct visual inspection made possible by eliminating the water. Therefore, pushing the water out of the way ensures not only that the inspection can take place but also that it produces accurate and reliable information about the condition of the sewer line.
