I never fully understood how a simple flush of a few litres of water sends all my poop and toilet paper to the sewers. If the main drain is in the basement 10 feet below the surface, does that mean the sewer lies further below the surface? I would love to see a video on what actually happens when you flush the toilet. TIA.

It just flushes into a pipe into the sewer. It’s not particularly complicated, aside from the P-trap (U-bend) on the pipe that keeps the sewer odors from entering your home.
Water from the toilet tank enters the toilet bowl and pushes downward on the waste and stagnant toilet water. This is then pushed through the P-trap and into the main drain line, where it empties into the sewer. The following (clean) water from the toilet tank settles into the toilet bowl and the P-trap, keeping the smell away and being ready to receive your next excretion.
