Did you know that the word plumbing comes from the Latin word plumbum, which means lead. Originally, plumbing pipes were made from lead. Today, a lot of plumbing pipes are made of PVC piping and sometimes copper, and the advancements in the plumbing field have done wonders for the quality of homes. Copper tubes for plumbing date back to 2750 BC, although lead was more common.
Is your bathroom sink not draining? If so, you should definitely call a plumber, because any number of things can be causing a blockage in pipes. Professional plumbers have a skill which will always be needed, as people are clogging up pipes all the time, and most people are unable to fix blockages themselves. A plumbing contractor will always be happy to fix anything you need fixed pertaining to the drainage in your house.
Aside from having working pipes, another way to make sure your house is of top quality is to install heating and cooling units. People have been trying to control the temperature of their environments for thousands of years. In the third century, Roman Emperor Elagabalus actually dispatched 1,000 slaves to the mountains so they could fetch snow for his gardens.
Today, slaves do not need to go to the mountains to get snow. Fortunately, slavery has been outlawed, and air conditioning units exist. In 1947, S.F. Markham said the greatest contribution to civilization might be air conditioning, and America was leading the way. In 1953, over a million air conditioning units were sold.
