Learn how to install a central vacuum system with outlets on four floors and hidden PVC piping.
Use a right-angled drill and a large wood bit with a long shank to bore a hole through the top plate of the second story wall frame directly above the intended vacuum outlet. This step begins the process of running piping from the attic through the wall to the second story vacuum outlets. If you run into nails, you will need to move slightly to the side and drill again to ensure the hole is clear to accommodate the PVC pipe.
