Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone.
Pipe normally has thicker walls and may be threaded or welded, while tubing is thinner-walled and requires special joining techniques such as brazing, compression fitting, crimping, or for plastics, solvent welding.These joining techniques are discussed in more detail in the piping and plumbing fittings article.

It is worth to choose just those who practice for a long time and they know everything about the operation and installation of plumbing in buildings.
Plumbing originated during ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese cities as they developed public baths and needed to provide potable water and wastewater removal, for larger numbers of people.6 Standardized earthen plumbing pipes with broad flanges making use of asphalt for preventing leakages appeared in the urban settlements of the Indus Valley Civilization by 2700 B.C.7 The Romans used lead pipe inscriptions to prevent water theft. Plumbing reached its early apex in ancient Rome, which saw the introduction of expansive systems of aqueducts, tile wastewater removal, and widespread use of lead pipes..
With the Fall of Rome both water supply and sanitation stagnated?or regressed?for well over 1,000 years.
Improvement was very slow, with little effective progress made until the growth of modern densely populated cities in the 1800s.During this period, public health authorities began pressing for better waste disposal systems to be installed, to prevent or control epidemics of disease. Earlier, the waste disposal system had merely consisted of collecting waste and dumping it on the ground or into a river. Eventually the development of separate, underground water and sewage systems eliminated open sewage ditches and cesspools.Źródło: https://en.wikipedia.org/wiki/Plumbing
