Plumbing basically refers to the system of drains, pipes, valves, fittings as well as fixtures that is installed for the sake of distributing water that is potable for heating, washing and drinking purposes. It also encompasses removal of waterborne waste. At other times, ‘plumbing’ is used to refer to the skilled trade dealing with both the installation as well as maintenance of these associated facilities.
The plumbing contractor field is generally a basic as well as substantial section of each and every developed country. The word ‘plumbing’ is derived from Latin’s “plumbum” which means lead. This is because the very first and effective pipes made use of during the Roman era were lead pipes.
“Plumbing” more often than not is used to refer to both the waste and supply system of a particular single building. This distinguishes plumbing from sewage systems and water supply since these two are normally at the service of more than one building.
Systems in plumbing companies
The main categories of systems (or subsystems) of plumbing most commonly made use of in the plumbing industry are:
- Potable hot and cold tap water supply
- Plumbing venting of the drainage
- Septic systems and sewage systems with (or without) recycling of heat of hot water and graywater treatment and recovery systems.
- Surface, subsurface as well as rain water drainage system
- Piping of fuel gas
- These are systems of both cooling and heating that utilize water in transporting thermal energy. This is as it is in a district heating system, for instance in the New York City steam system.
Materials used in the plumbing industry
The ancient times’ water systems depended solely on the natural gravity for supplying water making use of channels and pipes which were made of lead, clay, wood, bamboo and even stone. Wooden logs which had been hollowed were usually wrapped in steel banding and were utilised as plumbing pipes, especially water mains. Logs were made use of in distributing water in England around 500 years ago. The cities of United States, on the other hand, started using hollowed logs during the late 1700s until the 1800s. In the contemporary times however, a typical pipe used in plumbing supply is made from steel, plastic and copper. A lot of the waste (also referred to as ‘soil’) pipes in the today plumbing industry are made out of cast iron, plastic, copper as well as steel.
The parts of plumbing system that are straight are the ones referred to as the ‘tubes’ or ‘pipes’. Pipes are typically formed through welding or casting while tubes, on the other hand, are made via extrusion. Pipes usually have thicker walls and are welded or threaded while tubes are much thinner and call for special techniques of joining such as compression fitting, brazing or crimping.
