PVC pipe, or Poly Vinyl Chloride pipe, is a relatively modern type of piping, used most often in drinking water systems and other cold-water installations. When there is a need for foodstuffs or ultra-pure liquids in manufacturing applications, PVC pipe or stainless steel pipe is usually used.
This plastic piping has been in use in the United States since the 1960s, and these days PVC pipe often replaces metal pipe in new kitchens and bathrooms.
Health Concerns of PVC Pipe
There has been some controversy over the health issues of PVC in recent years. Some of the chemicals in the plastic used in PVC pipe have been reported to leech out over time and may affect the water supply if drinking water or shower water is supplied via a PVC pipe.
Flexibility of PVC Pipe
PVC pipe can withstand vigorous movement and a certain degree of bending without cracking. PVC pipe is therefore often used in earthquake-prone areas or in areas where there is periodic land settling.
