1. Plumbing originated during ancient civilizations, as they developed public baths and needed to provide potable water and wastewater removal for larger numbers of people.
2. The Mesopotamians introduced the world to clay sewer pipes around 4000 BCE, with the earliest examples found in the Temple of Bel at Nippur and at Eshnunna,[7] utilised to remove wastewater from sites, and capture rainwater, in wells.
3. Copper piping appeared in Egypt by 2400 BCE, with the Pyramid of Sahure and adjoining temple complex at Abusir, found to be connected by a copper waste pipe.
4. The word "plumber" dates from the Roman Empire.[13] The Latin word for lead is plumbum. Roman roofs used lead in conduits and drain pipes[14] and some were also covered with lead. Lead was also used for piping and for making baths
5.The use of lead for potable water declined sharply after World War II because of increased awareness of the dangers of lead poisoning. At this time, copper piping was introduced as a better and safer alternative to lead pipes.
6. Copper pipe not only doesn't rust but it also is naturally anti bacterial
