You can rent a heavy-duty 50-100 foot drain auger (snake) from a hardware store. Feed it into the cleanout until you hit resistance. Crank it through the clog. Run a garden hose to flush debris. Warning: This is physical, messy work. If the snake gets stuck or tangles in roots, you risk breaking the pipe.
This single pipe carries everything you flush or pour out of your house to either the municipal sewer system or your septic tank. It is the aorta of your wastewater system. When that artery gets blocked, every single fixture in the house above that blockage is compromised. Unlike the vertical drops inside your walls, the main drain runs horizontally (with a slight slope) under your concrete slab or basement floor and out to your yard. Its horizontal nature makes it prone to specific types of clogs. main drainage pipe clogged
Find your main line cleanout—a capped pipe sticking out of your yard or basement floor. Remove the cap. If water shoots out, the line is blocked past the cleanout. If nothing happens, the block is between the house and the cleanout. You can rent a heavy-duty 50-100 foot drain
If you ignore these whispers, the shouting will begin: raw sewage bubbling up through your downstairs tub, an inch of grey water on the garage floor, or the dreaded "gurgle-gush" from every drain in the house when you run the washing machine. Run a garden hose to flush debris
Pouring bacon grease, cooking oil, or gravy down the kitchen sink is a slow-motion crime. Hot grease is liquid, but as it travels down the cool iron or PVC pipe, it solidifies. Over years, this creates a hard, soapy, concrete-like layer inside the pipe. Eventually, the pipe’s 4-inch diameter shrinks to 1 inch, and a single grain of rice can trigger a total blockage.
