Yeah, I gotta admit that the central vacs are about as much trouble as
they are worth. The best thing about them is that 100% of the dust gets
exhausted outside the house, so no dust at all inside. I know they have
regular vacs now with fancy HEPA filters that I suppose work pretty
well, but from what I have seen, a replacement filter for one of them
costs almost as much as the machine does. I got my central used for $50,
and probably another 100 for the wall boxes, fittings, a piece of pvc
and hose. The PVC is some oddball size (of course) but I used regular
pvc and fittings - 2" as I recall- all under the house, and rigged up
the special crap to hook up to it right as it came through the floor. No
way would I have ever paid the $$$ for a new one, much less paid for one
installed. Larry
