The shocking update is......... i hate going under my house. The other shocking news is..... the system is in and working very well. There is no comparing of the suction power of a regular vacuum to a central vacuum. The only trouble i had was the kit was supposed to come with wire but they did not put it in the box and I needed extra couplings plus 1 extra stick of pipe.
All in all it was amazingly easy and inexpensive. I still came in around 400.
Now, if I could just get the "roomba" to drag the new vacuum hose around!
