A sewer line is a general term for any pipe transporting wastewater, whereas a main line (or main sewer line) is the specific central pipe that collects all of your home's wastewater and connects it to the municipal sewer system or septic tank.
Are the sewer line and the main line the same thing? Not exactly. The main line is the largest pipe in your home's drainage system, while the sewer line refers to any pipe that transports wastewater to the sewer system.

Replacing a sewer line is a major job that usually takes between one and five days, depending on the depth of the pipe, the length of the run, and how easily contractors can access the work area. In dense places like New York City, underground utility lines often make the job slower, sometimes requiring hand…
To clear a main sewer line clog, use an industrial-strength chemical main line opener (like Green Gobbler Main Line Opener or Instant Power Main Line Cleaner), or physically clear the blockage using a motorized drain auger (sewer snake). For severe blockages or tree roots, an auger is the most effective solution.

The "135-degree rule" in plumbing states that the total (aggregate) horizontal change in direction for a drainage pipe—specifically trap arms—cannot exceed 135 degrees between the P-trap and the vent. Exceeding 135 degrees (such as using three 45-degree bends or a 90 and two 45s) requires a cleanout because sharp turns hinder flow and cause clogs.
Over time, repeated use of chemical cleaners can weaken pipe walls, warp plastic piping, and corrode older metal lines. This gradual damage often leads to leaks, cracked pipes, and sudden plumbing failures that require emergency repairs. Another problem is that drain cleaners do not solve the real cause of most clogs.

Instead, they suggest preventing buildup through daily habits, using natural enzyme or enzymatic cleaners for maintenance, and letting professional cleaners clear severe blockages.
Baking soda and vinegar do not effectively unclog drains. Instead of clearing debris, mixing them chemically neutralizes both ingredients into salt water. The fizzing reaction is visually satisfying but largely escapes upwards, offering zero power to dissolve grease, hair, or stubborn sludge.
