Did you know that the word plumber goes back as far as the Roman Empire in history? In Latin, lead was called plumbum, which is where the periodic table of elements gets the Pb initials for lead. Back in the Roman era, lead was used for quite a bit of things, even building roofs, piping, and bath making. Therefore, anyone that had a deftness with handling and installing lead (not just a person who worked with sewage, water and drainage) was known as a Plumbarius (shortened later to plumber).
Nowadays, Plumbers in Little Rock AR would not have to be concerned with any federal laws that would require licensing, however, depending on what the state or location mandates may be different. Most often as you see plumbing services advertised, the ad will say something about the company being licensed though. A plumber is not someone that just hops on the job and learns it quickly. There is plenty of training and experience that is needed. Some of these skills that would be needed are the ability to find the design of waste, venting systems, and water supply; anything that might have to do with piping (such as locating them, preparing the pipes properly, and repairing the problem); being able to use water pressure gauges and the full awareness of all safety regulations and issues. Even though it may not be known, there is a lot that goes into being a respected plumber.
There are plenty of Plumbers in Little Rock AR to choose from that range from the family owned business that is only located in town to big name companies, such as Roto-Rooter plumbing & Drain Service. A company like Roto-Rooter can serve you at home and commercially should your need for a plumber be at your business and not at your residence. A lot of the services done for residential are done for commercial as well, just on a larger scale. Some, but certainly not all, of the services that plumbers pride themselves on being able to complete are the replacement and repair of faucets, toilets, sinks, showers and tubs, sewers and drains, dishwashers, septic tanks, and water heaters.
