Plumbing through History
Plumbing is known to have started with the Indu Valley Civilizations by 2700 B.C; they developed a system of standardized earthware plumbing pipes with broad flanges making use of asphalt to prevent leakages.
Over the centuries innovations and improvement in plumbing were very slow, not much progress was made from the time of the Roman system of Aqueducts to the lead pipes of the 19th century. Worth noting that the development of separate underground water and sewage systems eliminated open sewage ditches and cesspools.
During the past century was when plumbing evolved; before water systems relied on gravity for the supply of water, using pipes or channels, nowadays water systems are a network of high pressure pumps supplying water to all the house of a city or village.
Another thing that evolved with time was the materials used to make the pipes, ancient civilizations used to make them with clay, lead or stone. With the arrival of the high pressure pumps these pipes were replaced by pipes made out of copper, brass or plastic.
With all these new inventions and developments a new career emerged, the plumbing career. The plumber is a work man who installs and repairs piping, fixtures, appliances, and appurtenances in connection with the water supply, drainage systems, etc., both in and out of buildings.
Nowadays to become a professional plumber you will need certain qualifications and courses according to the area you live in. Today there are many colleges and private institutions that offer Professional Plumbing Courses.
What you need to pay attention is if the plumbing course cover all the legal requirements needed to work as plumber in your area, especially in the US where laws can vary from one state to another.
