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.

Clogged screen: Many kitchen faucets have an aerator screen that improves water flow. These can become gradually clogged, resulting in reduced water pressure. These can usually be removed easily by unscrewing them from the end-point of the faucet. If you need to use a wrench or pliers, be sure to cover the metal with cloth to prevent scratching. Just rinse out the screen and screw it back on.
Mounted under the sink, the garbage disposal is meant for chopping up small bits of waste food.  When switched on the motor spins and impellers — also called lugs — throw bits of food against a grinder ring. You should always run water while using the garbage disposal; once the garbage disposal does its job, the water flushes the finely chopped particles down the drain.

Despite the Romans' common use of lead pipes, their aqueducts rarely poisoned people. Unlike other parts of the world where lead pipes cause poisoning, the Roman water had so much calcium in it that a layer of plaque prevented the water contacting the lead itself. What often causes confusion is the large amount of evidence of widespread lead poisoning, particularly amongst those who would have had easy access to piped water.[14] This was an unfortunate result of lead being used in cookware and as an additive to processed food and drink, for example as a preservative in wine.[15] Roman lead pipe inscriptions provided information on the owner to prevent water theft.
