Plumbing is the system of pipes, fixtures, and appliances that are used for heating, cooling, and draining water and other fluids. It is a vital part of our daily lives, and its importance cannot be overstated.
Plumbing involves several key components, including water treatment, pipe materials, fitting types, valves, and appliances. The process of plumbing can range from simple fixtures like toilets and sinks to complex systems like sewage treatment plants and oil refineries.
Regulations regarding plumbing vary by country, state, or region. In the United States, for example, the Environmental Protection Agency (EPA) sets standards for lead-free soldering in water supply systems.
