The pipes and wiring can be roughed in before the drywall is up and at the same time as the electrician is finalizing. Temporary plaster guards are utilized on the stud-mounted backing plates to protect the interior of the pipe while drywall, mud, and paint are being completed.

What is the best way of cutting and gluing a PVC?

Avoid clogs, cut the pipe with a tubing cutter (not a hacksaw), and remove all burrs from the cut edge—Glue the male end only of the joint to prevent forming glue ridges inside the pipe connection. Central vacuum pipes and fittings are made to join seamlessly, so the air travels without interference and prevents objects from hanging up. Primer is not required.

Wiring the system?

Every inlet valve will have a 20-gauge, stranded pair, low voltage wire that should be spliced into a single line that follows the PVC pipe back to the power unit. Various inlet valves also have 110-volt inlets to power an electric power brush. An electrician can straightforwardly connect the valves’ 110-volt wires to a nearby electrical outlet.

Penetrating the firewall?

Check local construction codes concerning the necessity of a steel pipe or fire collar to penetrate the firewall. If the PVC pipe connected to the power unit passes through a firewall (usually plywood behind wallboard), ensure you abide by all building safety codes.
