when did they start using pvc for plumbing
Plumbing 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.
Thomas Crapper The flushing toilet was invented by John Harington in 1596. Joseph Bramah of Yorkshire patented the first practical water closet in England in 1778. George Jennings in 1852 also took out a patent for the flush-out toilet.[4][5] In a time when bathroom fixtures were barely spoken of, Crapper heavily promoted sanitary plumbing and pioneered the concept of the bathroom fittings showroom.[citation needed]
