Inlets and inlet valves for your central vacuum system

When planning the installation of your central vacuum system one of the things to consider is the placement, style and colour of the inlet valves you will have on your wall. The inlets will be on your wall for many years.


We usually recommend the inlets are installed at the same height of the power points (usually 330-350mm off the floor). Having the inlet at the same height as the power point looks good but also makes inserting the house convenient.

When installing the inlet on the same wall as a light switch, we like to install the inlet directly below the light switch. The symmetry of having the inlet under the light switch helps blends the inlet into the wall.

We have also installed inlets at knee height, shoulder height, on the floor and also the same height as light switches. It is your home and your choice.


The goal is to ensure that the central vacuum inlets robust but also aesthetically pleasing. Inlets are available in plastic, metal and even glass. We have installed > 10,000 inlets in new and existing homes in Auckland and our experience is that PVC plastic inlets will last the test of time and come in various styles.


We recommend that the colour of the central vacuum inlet valves match the colour of the light switches and power points. This ensures that like the switches in your home, the vacuum inlets are conspicuous and are consistent with the colour theme throughout your home. The most comment colours we see are white (about 95% of homes), black and silver. We can paint the inlets any colour with the provision of a test pot / colour code.
