Laws, regulations & standards

A Plumbers Technical Note from Building and Energy has confirmed the new Plumbing Code of Australia (PCA) will come into effect in WA on 1 May 2023.

It will replace PCA 2019.

Because only water supply, sanitary and drainage plumbing work are regulated in WA, the relevant parts of the PCA are

  • Section A
  • Parts B1, B2, B3, B4 and B5
  • Parts C1 and C2
  • Specification 4

The PCA is Volume Three of the National Construction Code and available free of charge from the Australian Building Codes Board.
