Residential main sewer lines and drain lines can become clogged over time from buildup. Residential sewer and drain lines can be snaked with a professional drain snaking machine. The drain line snake uses a heavy-duty cable and motor to push the blockage through the pipe. Main sewer line snaking can be done through a ground level accessible cleanout, a roof vent, or by pulling the toilet and snaking through the flange. Another option to unclog drain lines is to use High Velocity Water Jets, or Hydro-Jetting. This sewer jetting process pushes water at a high velocity through your pipes. The water helps to emulsify and remove debris that has accumulated on the walls of the pipes.
