Fact

Almost every central vacuum cleaning system in a home, store, office or similar application is assembled with a plastic (PVC) piping system. Plastic does not conduct and therefore becomes somewhat static during use. Because the central vacuum system is turned off automatically after use, the piping system has the opportunity to discharge itself.

Fable

It is a myth that anti-static piping systems are available, for example, in PVC or PPC. Also, there are no plastic fittings for piping systems that would not become static. It is said, but again: it is not true! Only grounded metal piping systems are able to conduct staticity immediately.
