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.
A pipe is typically formed via casting or welding, whereas a tube is made through extrusion.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.Źródło: https://en.wikipedia.org/wiki/Plumbing#Materials
The implementation of specific services hydraulic ordered also by owners of residential houses, where you need to install new sanitary or check the efficiency of their operations.
The homes can also occur failure of hydraulic such as rupture of the seal or hose from the washing machine and the lower belt in a washing machine.
Plumbing equipment includes devices often hidden behind walls or in utility spaces which are not seen by the general public.
It includes water meters, pumps, expansion tanks, backflow preventers, water filters, UV sterilization lights, water softeners, water heaters, heat exchangers, gauges, and control systems. Specialized plumbing tools include pipe wrenches, flaring pliers, pipe vise, pipe bending machine, pipe cutter, dies and joining tools such as soldering torches and crimp tools.
For example, plumbers use video cameras for inspections of hidden leaks or problems, they use hydro jets, and high pressure hydraulic pumps connected to steel cables for trench-less sewer line replacement.Źródło: https://en.wikipedia.org/wiki/Plumbing#Equipment_and_tools.
