Installing Central Vacuums in Concrete Homes

Back to Installation Manuals

The following images are from our representative in Israel. Many homes around the world are made by pouring concrete or with block concrete, and therefore have unique installation requirements. Here in the states, concrete homes are becoming more of a luxury.

The image below shows how the PVC vacuum pipes can be laid out before being covered with 10 -15 centimeters of sand. Do a complete pressure test prior to pouring the sand to find and fix any problems. To ensure integrity and longevity, put the 2" pipe inside a 3" PVC outer shield for maximum protection. This is especially true of poured floors - walls are less of an issue.

Inlet valves are cut into the wall and low voltage wire is ran in a separate conduit. Use a #515 mounting bracket with a tight 90 #501 (or a flanged tight 90 #524 to use less space), OR use backing plate #511MP with #511SN short 90.

In homes where concrete is poured in the walls after the pipe is run, use the concrete back up plate #515M and standard vacuum PVC pipe.

Pipe is layed into the concrete block after a routter hammer is used to access the channel in the block.
