Before we dive into the specifics of drain cleaning, let's start with the basics. What exactly are drains, and how do they work?

Drains are a vital component of any home's plumbing system. They are responsible for carrying waste water and sewage away from your home and into the main sewer system. Every time you flush the toilet, take a shower, or wash dishes, the waste water and sewage is directed into the drainpipes and out of your home.

Drains work through a combination of gravity and pressure. The pipes are sloped downward so that the waste water and sewage can flow out of your home and into the sewer system. The water and waste are moved along the pipes by the power of gravity, with additional pressure added by the force of water flowing through the pipes.
