Step 2: Secure the Hose, and Turn on the Machine

Insert the hose as far as it will go. Secure the hose.

Use a specialized camera (Image 2) to ensure the clog is removed, the line is clear and that there are no breaks on the lines. Run the sewer camera down the entire length of the drain line all the way to the septic tank.
