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.
Plastic supply pipes have become increasingly common, with a variety of materials and fittings employed. PVC/CPVC ? rigid plastic pipes similar to PVC drain pipes but with thicker walls to deal with municipal water pressure, introduced around 1970.PVC stands for polyvinyl chloride, and it?s become a common replacement for metal piping.
PVC should be used only for cold water, or for venting.CPVC can be used for hot and cold potable water supply.
PP pipe is often used in green building projects.1415 PBT ? flexible (usually gray or black) plastic pipe which is attached to barbed fittings and secured in place with a copper crimp ring.The primary manufacturer of PBT tubing and fittings was driven into bankruptcy by a class-action lawsuit over failures of this system.citation needed However, PB and PBT tubing has since returned to the market and codes, typically first for "exposed locations" such as risers. PEX ? cross-linked polyethylene system with mechanically joined fittings employing barbs, and crimped steel or copper rings. Polytanks ? plastic polyethylene cisterns, underground water tanks, above ground water tanks, are usually made of linear polyethylene suitable as a potable water storage tank, provided in white, black or green. Aqua ? known as PEX-Al-PEX, for its PEX/aluminum sandwich, consisting of aluminum pipe sandwiched between layers of PEX, and connected with modified brass compression fittings. In 2005, a large number of these fittings were recalled.further explanation needed Present-day water-supply systems use a network of high-pressure pumps, and pipes in buildings are now made of copper,16 brass, plastic (particularly cross-linked polyethylene called PEX, which is estimated to be used in 60% of single-family homes17), or other nontoxic material.
Due to its toxicity, lead has not been used in modern water-supply piping since the 1930s in the United States,18 although lead was used in plumbing solder for drinking water until it was banned in 1986.18 Drain and vent lines are made of plastic, steel, cast-iron, or lead.1920 Źródło: https://en.wikipedia.org/wiki/Plumbing#Plastic
A plumber is a tradesperson who specializes in installing and maintaining systems used for potable (drinking) water, sewage and drainage in plumbing systems.
The Latin for lead is plumbum.
