Plastic - about material
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.
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. Connections are made with primers and solvent cements as required by code.12
PP ? The material is used primarily in housewares, food packaging, and clinical equipment,13 but since the early 1970s has seen increasing use worldwide for both domestic hot and cold water. PP pipes are heat fused, being unsuitable for the use of glues, solvents, or mechanical fittings. 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
Replacing the tub bathroom on the new
After some time the use of the bath can choose to replace it. The reason for such a decision may be pouring the water out of the tub while taking a bath, which may indicate that the bath does not have a good run-off. But the replacement of the bath may be caused by the desire to be placed in the bathroom of a new sanitary facilities, which will look more modern and well-maintained. To be able to replace the bath with a new, employed by us plumber will have to weld the plate, in which the tub is built, and then remove the old tub from the bathroom. Installation of a new bathroom bathtub may be combined with replacement pipes for water from the tub so that it will serve us to reliably for many years.
When it is necessary to service the hydraulic?
Many people every day not remember the existence of hydraulic services. Often, a lot of repairs are made independently, without taking into account that a good specialist would do much better, cheaper and easier. If we want to save yourself time and facilitate such matters, you should know that many of them much simpler solution would be to call a plumber to fix everything for us. Such services Hydraulic help us in case of broken pipes, clogged drain, not localized leaks or other malfunctions that cause discomfort and limit our freedom. Good services quickly deal with them can handle and provide us save time and money.
