To deliver natural gas, this Gas Piping Plan relies on pressure. The flow of gas is from higher to lower pressure. After being extracted, natural gas travels through a highway-like network of pipes in distribution systems that bring the gas into your home. Gas flows from the distribution line, also known as a mainline, into a home or other building via a service line maintained by the natural gas utility. According to this Gas Piping Plan, customers are responsible for all equipment and gas supply lines downstream of this service line. Before entering your home, the gas is routed through a pressure regulator to reduce its pressure.
