Plumbing is any such system that carries liquids for various purposes. The two most common and widely used plumbing systems are the private line and public line plumbing. Private line plumbing utilizes individual pipes, fixtures, valves, and other apparats to carry liquids. Public line plumbing, on the other hand, is utilized by large commercial enterprises as well as residential homes and is widely used throughout the world.


There are basically two different kinds of plumbing; potable and non-potable. Potable plumbing, as the name suggests, carries water from one place to another. The most common plumbing in the United States is private line plumbing. This kind of plumbing comprises of fixtures such as faucets, bath tubs, sinks, toilets, showers, laundry facilities, drains, traps, and pipes. On the other hand, non-potable plumbing refers to systems that transport liquids or contain materials that are not fit to be flushed from the plumbing.


In the United Kingdom, a distinction is made between three kinds of plumbing systems namely domestic plumbing, community plumbing, and water-supply. The main difference in these systems is the type of supply used. Domestic plumbing refers to individual household plumbing which delivers water directly to the taps. Community plumbing provides water for the entire community or town and is generally managed by a local governing body. Water-supply is the supply line used by local plumbers.


One of the most commonly installed systems in the United Kingdom is the hot water system Heidelberg. CSPS is made out of high-density polyethylene (HDPE), low-density polyethylene (LDPE), or standard polyethylene (SAP). These pipes pass through two layers of insulation namely the outer layer of insulation, which is made from polystyrene, and the inner core made of polycarbonate. This makes it possible for potable water supply to withstand any temperature ranging from -12 degrees Celsius to +50 degrees Celsius. One of the most common types of CSPS pipes is the galvanized steel pipe.
