Installation of a central vacuum system in existing
constructions is not only possible but in most cases is
quite simple.
while there can be extra challenges to installing in some
existing houses, often the installation is much easier
than anticipated.

Many houses may only require two or three wall valves,
and access to these may sometimes be made underfloor,
or through a cupboard as an example.

Double brick or concrete constructions will require
greater planning and expertise, and often may involve
the assistance of the builder. this guide is not intended
to address those types of installations or applications.
In relation to the standard timber frame construction, the
pVC ducting will be installed at "frame stage".
once the Inlet Valve location has been decided, the
mounting plate can be fixed to the stud with nails or
screws. ensure you have the chosen the best height,

which may often be at the same height as power points
for consistency.
the pVC duct, together with the low voltage wiring
will run through to the bottom plate, or up through the
nogging and top plate.
once the home is completed, the inlet valves can be
installed, preferably after the walls have been painted.
the two lugs on the wall valve will be connected to the
cable, or 2 cables if the wiring at that valve is looped to
the next wall valve.
Hold the wall valve with the hinge at the bottom, and
with a twisting motion, slide the rear of the valve into
the mounting plate. do not use glue as the gasket in
the mounting plate will provide a positive seal. If the
valve does not reach the mounting plate an inlet valve
extension can be used.
Flaps up or down? many people prefer to install wall
valves with the flap hinging downwards for easy access
to the inlet. there is no correct way - hinge up or hinge
down is up to your personal preference.
Simply screw the wall valve to the mounting plate to
complete the task. If the pVC ducting is directly behind
the screw locations be sure to use short screws that will
not reach and puncture the duct.
