Plumbing is the system or network of pipes, tanks, fittings, and other fixtures required to build water supply, heating and sanitation systems in a building. Heating, cooling, gas fitting, water removal, and supply of potable water are some of the important parts of this profession. This profession follows the basic laws of pressure, gravity, water level, etc. It is hard for a common man to understand the complexities and the mystery of plumbing. This is why we need plumbers every time we face a plumbing-related problem.
