—usually a white or black pipe with a screw-on cap located outside your house or in the basement. 1. The "Release the Pressure" Method If your main line is full, opening the cleanout cap can cause a "geyser" of sewage. Loosen slowly: Use a pipe wrench to loosen the cap, but do not remove it immediately. Drain the backup: Let the built-up water seep out slowly into a bucket or onto the ground (if outside) before removing the cap entirely. This relieves the head pressure in your home's pipes. 2. Use a Motorized Sewer Auger (The "Snake") For a main line, a standard hand snake won't work; you need a heavy-duty motorized auger (available for rent at hardware stores). Feed the cable: Insert the business end of the cable into the cleanout toward the street (or septic tank). Power up: Turn on the motor and slowly feed the cable. When you feel resistance, you’ve hit the clog. Chew through it: Let the rotating blades work against the blockage. Avoid forcing it; let the machine's torque do the cutting. Retrieve and repeat: Once the water level drops (indicating the clog has broken), pull the cable back, clean off any debris (roots, wipes, etc.), and run it through one more time to ensure a clear path. 3. Hydro-Jetting (For Heavy Sludge or Grease) If an auger doesn't work, you likely have heavy grease buildup or scale. A hydro-jetter uses high-pressure water (up to 4,000 PSI) to "scour" the inside of the pipes.
