Learn how to install a central vacuum system with outlets on four floors and hidden PVC piping.
Reattach the heavy metal washer to the low voltage cable and drop it down the chute and into the basement for connection to the vacuum power supply. Depending on your wiring plan, you may have multiple cables running from the attic and second floor vacuum outlets down the laundry chute to the power unit in the basement. The cable will follow the PVC piping runs back to the power unit and connect to it.
