You have to be careful with the PVC,(I'm not sure about other types of plastic) because it can build up a pretty (like REALLY) high static charge when stuff is flowing through it. Some people have used it for pipe in a central shop vac system, and have found that running a bare wire (like 14g electrical) along it (outside) and to a ground, taped down with the aluminum tape, helps keep the charge down, which could cause sparks and mayhem in a dusty environment. I even notice that in my roll-around shop vac when using a couple of hoses joined together, in the winter when it's dry you can get a nice ZAP!!!! off the thing. I don't know if that house vac stuff considers that aspect or not.

If you're building your own, you could use pvc plumbing pipe I'd think.... I guess the wall fittings might not mate up though.
