Installing a central vacuum system in an existing home can be a bit more challenging than in new constructions, as it involves retrofitting the system into the existing walls and floors. However, it is still possible to do it with the right tools and some DIY skills. Keep in mind that this is a general guide, and the specific steps might vary based on the central vacuum system you choose and the layout of your home. If you're not comfortable with electrical and carpentry work, it's best to hire a professional installer. Here's a general overview of the process:
1. Choose a Central Vacuum System: Research and select a central vacuum system that suits your home's size and needs. Consider factors like suction power, filtration, and the number of inlets required. Purchase the necessary components, including the central unit, piping, inlet valves, mounting brackets, and accessories.
2. Plan the Layout: Create a plan for the central vacuum system's layout. Determine the best location for the central unit, typically in a garage, basement, or utility room. Plan the routing of the PVC piping from the central unit to the various inlet valves throughout your home. Try to keep the piping runs as short and direct as possible to maintain optimal suction.
3. Gather Tools and Materials: Ensure you have all the necessary tools and materials for the installation, including PVC piping, fittings, PVC cement, mounting brackets, wire, low-voltage cable, outlet boxes, wall plates, electrical connectors, and screws.
4. Install the Central Unit: Mount the central unit in the chosen location, secure it properly to the wall or floor, and connect it to the electrical supply. Follow the manufacturer's instructions for installation.
5. Run PVC Piping: Begin running the PVC piping from the central unit to each inlet valve. You may need to cut holes in walls or floors to accommodate the piping. Use proper fittings and secure the pipes in place with mounting brackets.
6. Install Inlet Valves: Install the inlet valves in the walls at strategic locations throughout your home. Cut holes in the walls for the inlet valves and connect them to the PVC piping.
7. Connect Low-Voltage Wiring: Run low-voltage wiring from each inlet valve to the central unit. This wiring will control the on/off functionality of the central vacuum system when you plug in the hose.
8. Connect Electrical Wiring: If your central vacuum system requires electrical power for features like the motorized brush, follow the manufacturer's instructions to connect the electrical wiring.
9. Test and Adjust: After completing the installation, test the system to ensure proper suction and functionality. Make any necessary adjustments to optimize performance.
10. Install Wall Plates and Accessories: Install the wall plates on the inlet valves, and then set up any additional accessories that come with the central vacuum system, such as hoses, brushes, and attachments.
Remember that this is a general overview, and the process may be more complex depending on your home's layout and the specific central vacuum system you choose. Always refer to the manufacturer's installation instructions for the most accurate guidance. If you're unsure about any part of the installation process, consult with a professional installer to ensure a safe and effective installation.
