Dealer Warning
The new Hide-a-Hose system is becoming quite popular, and for good reason. It conveniently stores the hose inside of the vacuum tubing for easy access whenever the user wants to vacuum. We have written before on the issue and identified the pros and cons of the concept. Today we heard of a potential problem that can occur in the installation and a few simple warnings may avoid major headaches for you should you install these Hide-a-Hose systems.
First, if you run pipe up into an attic, you must insure that the attic remains below 147 degrees Fahrenheit. Any temperature above this tends to break down the viscosity of the pipe and it gets quite pliable This is true for any central vacuum system with pipes in the attic. The temptation; though, with Hide-a-hose is to run the pipes as a raceway tied up to the underside of the joists; suspended in the attic. Here the heat intensifies and thus problems can begin.
The pipe truly must be supported well for the hose to be able to easily slide in and out of the pipe. Looping it from every five feet of rafters will not make it rigid enough. The pipe, exposed to high temperatures will have a tendency to warp and sag and then fittings can come loose. You must also use quality pipe that has the ASTM 2158 approval stamped on it.
Another issue is that you should not place the Hide-a-Hose sweep 90’s too close to each other. We have heard reports that this makes it harder to suck the hose back into the walls. If you need to use fittings, you should make a “square-like” pipe design as opposed to an long oval.
Lastly, we are seeing Hide-a-Hose advocates such as HP Products recommend a high waterlift designed motor in the vacuum system used to operate the system. We certainly agree with them on this issue and would advocate our Model S4, S44, S5, M45, M85, M92, J, K, G23, and Model SV.
