Protecting health and safety

The Board is becoming increasingly aware of consumers carrying out D.I.Y and filtration companies using unauthorised people, such as their in-house ‘service technicians’, to install water filtration systems. As a result of this work being done by unauthorised people, the Board has seen a number of non-compliant installations.

Only those authorised[1] under the Plumbers Gasfitters and Drainlayers Act 2006 (the Act) can do any work that comes within the Act’s definition of sanitary plumbing, gasfitting and drainlaying.

This is to protect the health and safety of the public.

To assist consumers and filtration companies the Board has made this guidance informaton to help ensure it is clear what work must be done by someone authorised under the Act.



[1] There are different ways people can be authorised under the Act however, the most common way is to be registered and licensed.

Water Filters

Three of the common types of water filter systems are:

  1. Under bench
  2. Bench top
  3. Inline

Each type of water filter can be sanitary plumbing as defined in the Act.
