Hi All, I work in a home with such a system, and I have found one important, but otherwise trivial problem that one might not look for.
The outlets where you connect the vacuum hose. In the one house I work in, if you place repeated pressure on the outlet, meaning if you pull too much on the hose, since the hose has little give in terms of stretching capability, it can, and in my case, did pull out the outlet to the point where the wires were hanging out of the wall, and the outlet housing was stuck to the hose end. You might be wondering how and why the outlet came along with the hose end when it was pulled, and/or why the hose simply didn't come off the wall outlet when the hose was pulled. Well, the simple explanation is that the outlet looks like a pet door on a regular home door. It consists of a flap that covers the outlet when not in use. This flap has a lip that slides over the end of the hose when it is connected to the outlet, not allowing it to come off so easily. I guess this is done as a safety precaution, and as a feature, as those hoses would come off quite easily given the pressure with which you apply it when vacuuming. The owner has had to replace several outlets because of this, and, as you can imagine, it's not easy to do with wires connecting the outlet to the hose. Just something to think about in terms of future maintenance on such units. Victor Gouveia
