The plumbing system of your house performs two very separate functions. The first function is to bring water into the house for drinking, cooking, washing, and for providing a waste-water base for the toilet. For those on a public water supply system, this is generally accomplished using a combination of pipes, pumps, and gravity. Many homes still rely on wells with either electric pumps or plain-old “man-power” to draw the water from the well. The second function is to remove the waste water from the house. This almost always relies on gravity (and swirly motions in the toilet bowl.) Learn about your plumbing in the posts below.
