Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper, brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes), or other nontoxic material. Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States, although lead pipes were approved by national plumbing codes into the 1980s, and lead was used in plumbing solder for drinking water until it was banned in 1986. Drain and vent lines are made of plastic, steel, cast-iron, or lead.
Most states and localities require plumbers to be licensed. Although licensing requirements vary, most states and localities require workers to have 2 to 5 years of experience and to pass an exam that shows their knowledge of the trade and of local plumbing codes before they are permitted to work independently. In addition, most employers require plumbers to have a driver’s license.

"I needed to hire a painter for my place of business which is a hair salon. I hired Jose and he was just fantastic! His communication was very thorough and he was on time and he did a wonderful job. I actually needed him to repaint the room from a prior painter who did a very sloppy job. Jose made my room look bright and beautiful and on top of it he cleaned everything so thoroughly. He wanted to leave my room spotless and I could tell he took a lot of pride in his services. I was very impressed with his work and I have already hired him to do a plumbing job next in my salon. He is the nicest guy you want to work with and he has an excellent work ethic. He is very upfront and honest he will tell you what he can or cannot do and his prices are very fair. Jose is going to be my go to guy for any handyman work I need in my salon going forward. I highly recommend him for whatever your handyman needs maybe. This man is a true professional!"
