Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another.
The engineering discipline of piping design studies the efficient transport of fluid.12 Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete.
In earlier days, this was sometimes called Drafting, Technical drawing, Engineering Drawing, and Design but is today commonly performed by Designers who have learned to use automated Computer Aided Drawing / Computer Aided Design (CAD) software., Źródło: https://en.wikipedia.org/wiki/Piping
More often there are failures washing machines or dishwashers, which can prevent only a plumber.At the same time among plumbers, there is a lot of competition, so they are trying at all costs to attract and retain potential customers through various promotions.

However, many plumbers, dissatisfied with their wages go abroad in search of better-paid work and perform activities there, they do not want to do local plumbers.
A boiler is a closed vessel in which water or other fluid is heated.
The fluid does not necessarily boil.
(In North America the term "furnace" is normally used if the purpose is not actually to boil the fluid.) The heated or vaporized fluid exits the boiler for use in various processes or heating applications,12 including water heating, central heating, boiler-based power generation, cooking, and sanitation.Źródło: https://en.wikipedia.org/wiki/Boiler.
