Can I install ducted vacuum wall plate in the floor?

Floor Reducer Coupling for Ducted Vacuum

Ducted vacuum wall plates (also known as inlet valves, hose sockets, outlets) are usually installed in the wall, but in some cases they need to be installed in the floor.

Some common reasons to install ducted vacuum plates in the floor include:

  • If your home is already constructed and on stumps - this is a much easier installation method.
  • If you home has solid brick walls.
  • You simply prefer the appearance of inlet valves in the floor.


    Most ducted vacuum installation kits are supplied with stud mounting plates which provides a solid fixing point for the wall plate (since plaster walls are not strong enough to do this alone). The mounting plate also serves as a coupling between the wall plate and the rest of the pipework.

    When installing into the floor, the stud mounting plate is not required as the floor structure itself will provide a solid fixing point for the plate, but the coupling to connect plate and pipework together is still required. 

    This part is known as a floor reducer coupling.
    This is the only special fitting required to install a ducted vacuum plate in the floor.
    If you are ordering a DIY installation kit online and will be installing plates in the floor, simply make a note in the comments section on the checkout page to swap the mounting plates for floor reducer couplings and we will take care of the rest.
