Remove P-Trap and Clear Blockage — Open the Cleanout Cap

How to Use a Main Line Cleanout to Clear a Major Sewer Clog · Step 3 of 9
In this video
Wearing protective gloves, slowly loosen the slip nuts on both ends of the P-trap by turning them counter-clockwise. These can typically be loosened by hand. As the seals break, water will begin to drain into the bucket. Carefully lower and remove the P-trap section. A large volume of water will likely gush out. Once drained, inspect the removed pipe for the clog and clear it out. The clog is often a buildup of grease and food particles.
Goal: Disassemble the P-trap to access and remove the clog
- The water draining from the sink will be dirty and may gush out quickly. Loosen the final connection slowly to control the flow.

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.
