Work Through the Blockage — Retract and Clean the Cable
Part of project
How to Use a Main Line Cleanout to Clear a Major Sewer Clog · Step 7 of 9
In this video
Feed the cable into the drain until you feel it make contact with the blockage. The cable will begin to bind and build up torque, which you will feel. When this happens, use the auto-feed to retract the cable slightly, allowing the spinning head to work on the clog and break it up. Then, advance the cable forward again slowly. Repeat this process of advancing, feeling the torque, and retracting slightly. This patient, back-and-forth motion will allow the head to work its way through the blockage effectively.
Goal: Use the proper technique to break through a clog in the drain
- Do not try to force the cable through a blockage. Let the machine's rotation and the back-and-forth feeding motion do the work to avoid damaging the cable or pipe.
- Feeling the cable torque up is a sign that you have reached the blockage and the head is engaging it.

FAQs
What essential safety precautions should I take before attempting to clear a main line sewer clog?
Always wear heavy-duty latex gloves and protective goggles (like POWERTEC 71563) to prevent contact with raw sewage and debris. Lay down a large, heavy-duty polyethylene tarp (e.g., TARPCO SAFETY 24 ft. x 36 ft.) around the cleanout to contain any spills and make cleanup easier. Ensure the work area is well-ventilated, as sewer gases can be unpleasant and potentially harmful.
Can I use a regular hand-cranked drain snake for this project, or do I really need a motorized auger?
For a major sewer clog, especially one caused by tree roots as implied in the project, a regular hand-cranked drain snake is typically insufficient. You need a motorized drain auger (like the VEVOR 75 ft. models listed) because it provides the necessary power, torque, and cable length to break through tough obstructions deep within the main line, which hand snakes often cannot achieve.
What are common mistakes to avoid when operating the motorized drain auger for the first time?
Avoid forcing the auger cable; let the machine do the work slowly and steadily to prevent damaging your pipes or kinking the cable. Don't extend too much cable too quickly, as it can make retraction difficult and less effective. Always ensure the machine is properly grounded and that you have a firm grip on the cable as it feeds to maintain control.
Why is the estimated time for this project 6 hours, and what makes it 'intermediate' difficulty?
The 6-hour estimate accounts for the time-consuming process of locating the cleanout, slowly feeding the auger through stubborn obstructions like tree roots, and thorough post-project cleanup. Its 'intermediate' difficulty rating comes from handling powerful, specialized equipment, dealing with significant sewage, and the precise technique required to effectively clear the clog without damaging your plumbing system.
