Plumbing - what materials are we using?
Water systems in ancient times used gravity to move water. They used pipes or channels usually made of clay, lead, bamboo or stone. Today, water-supply systems use a network of high-pressure pumps, and pipes are now made of copper, brass, plastic, or other nontoxic material. Drain and vent lines are made of plastic, steel, cast-iron, and lead. Lead is not used in pipes today because it can be poisonous.
The 'straight' sections of plumbing systems are of pipe or tube. A pipe is usually made by casting or welding, where a tube is made through extrusion. Pipe usually has thicker walls and may be threaded or welded, where tubes have thinner walls, and needs special joining techniques such as 'brazing', 'compression fitting', 'crimping', or for plastics, 'solvent welding'.
As well as the straight pipe or tubing, many fittings are required in plumbing systems, such as valves, elbows, tees, and unions.
Plumbing fixtures are designed for the people who use the water. Some examples of fixtures include water closets (also known as toilets), urinals, bidets, showers, bathtubs, utility and kitchen sinks, drinking fountains, ice makers, humidifiers, air washers, fountains, and eye wash stations.
How to take care of the plumbing?
Any equipment or installation is exposed to some specific defects that occur during its use. Many of them can be easily repaired, but some require our specialized knowledge and skills. To avoid such problems, which can be particularly troublesome when it comes to plumbing, it is appropriate to deal with installations. To this end, regular checks and inspections, so that potential failures are detected before they even occur. Such inspections simply call the appropriate service to on-site check everything thoroughly. All it will take a little time, and with such a service gain confidence that will not meet us serious problem.
Plumbing - the not so modern history
Plumbing was very rare until modern cities grew in the 19th century. At about the same time, public health leaders began wanting better systems to get rid of waste. Before this, people got rid of waste by collecting it and dumping it onto the ground or into rivers. However, there were some plumbing pipes in the city settlements of the Indus Valley Civilization by 2700 B.C. Plumbing was also used during the ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese civilizations as they built public baths and needed drinking water, and somewhere to drain waste. The Romans used pipe inscriptions to stop people from stealing water.
These systems did not improve much over the years. There were almost no improvements from the time of the Roman aqueducts and lead pipes until the 19th century. Eventually the development of separate, underground water and sewage systems got rid of open sewage ditches and cesspools. Most large cities today send solid wastes through pipes to sewage treatment plants. Treatment separates water from waste and makes the water more pure before it goes into streams or other bodies of water. Most places stopped using lead for drinking water after World War II because of the dangers of lead poisoning. At this time, copper piping was started because it was safer than using lead pipes.
