Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper,[25] brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes[26]), or other nontoxic material. Due to its toxicity, most cities moved away from lead water-supply piping by the 1920s in the United States,[27] although lead pipes were approved by national plumbing codes into the 1980s,[28] and lead was used in plumbing solder for drinking water until it was banned in 1986.[27] Drain and vent lines are made of plastic, steel, cast-iron, or lead.[29][30]

An apprenticeship is the most common pathway to becoming a plumber. Many unions and businesses mandate that an apprentice receive a minimum of 246 hours of technical education, which could include instruction in math, applied physics and chemistry, and up to 2,000 hours of paid, practical training working with an experienced plumber. Safety training is also an important component of the process, since injuries are common in this line of work. "We have many hours worth of [Occupational Safety and Health Administration] training before we go on to a job site," says Patrick Kellett, the administrative assistant to the general president for the United Association of Journeymen and Apprentices of the Plumbing, Pipe Fitting Industry of the United States, Canada and Australia. "We're very conscious of the dangers that come with working in construction."

Our water heater busted on Saturday. Sean came right out and was very informative and helpful. He explained that they would need to secure our type of water heater and once successful he would be out first thing Sunday morning to install it. He was here first thing at 7:30 AM with a smile on his face and removed the old water heater and installed the new one in no time. Sean is very knowledgeable and personable. My husband and I enjoyed talking about Football with him while he was here. I would also like to mention Tiffany, the dispatcher, she was great as well, very helpful when I made the initial call. I would definitely recommend Atomic Plumbing and Sean to anyone needing plumbing work done in the future.
Cast iron and ductile iron pipe was long a lower-cost alternative to copper, before the advent of durable plastic materials but special non-conductive fittings must be used where transitions are to be made to other metallic pipes, except for terminal fittings, in order to avoid corrosion owing to electrochemical reactions between dissimilar metals (see galvanic cell).[17]

Plastic pipe is in wide use for domestic water supply and drain-waste-vent (DWV) pipe. Principal types include: Polyvinyl chloride (PVC) was produced experimentally in the 19th century but did not become practical to manufacture until 1926, when Waldo Semon of BF Goodrich Co. developed a method to plasticize PVC, making it easier to process. PVC pipe began to be manufactured in the 1940s and was in wide use for Drain-Waste-Vent piping during the reconstruction of Germany and Japan following WWII. In the 1950s, plastics manufacturers in Western Europe and Japan began producing acrylonitrile butadiene styrene (ABS) pipe. The method for producing cross-linked polyethylene (PEX) was also developed in the 1950s. Plastic supply pipes have become increasingly common, with a variety of materials and fittings employed.
