Draft Designation: DR 101256This Standard incorporates Amendment No. 1 (September 2017). The changes required by
the Amendment are indicated in the text by a marginal bar and amendment number against
the clause, note, table, figure or part thereof affected.
The objective of this Standard is to provide installers with solutions to comply with—
(a) the National Construction Code of Australia (NCC), Volume Three, Plumbing Code
of Australia (PCA); and
(b) the New Zealand Building Code (Clause G12, Water Supplies).
This Standard is part of a series for plumbing and drainage, as follows:

3500.0 Part 0: Glossary of terms
3500.1 Part 1: Water services (this Standard)

This revision include changes aligning the requirements with the Plumbing Code of
Australia.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the
application of the appendix to which they apply. A ‘normative’ appendix is an integral part
of a Standard, whereas an ‘informative’ appendix is only for information and guidance.
Statements expressed in mandatory terms in notes to figures and tables are deemed to be
requirements of this Standard.
Notes used in this Standard are of an advisory nature only and are used to give explanation
or guidance to the user on recommended considerations or technical procedures, or to
provide an informative cross-reference to other documents or publications. Notes to clauses
in this Standard do not form a mandatory part for compliance with this Standard.
This Standard includes a commentary on some of the clauses. The commentary directly
follows the relevant clause, is designated by ‘C’ preceding the clause number and is
printed in italics in a box. The commentary is for information and guidance and does
not form part of the Standard.
Some materials and products used in a water service are provided with instructions for
installation and use. Whilst not a requirement of this Standard , or acceptable as an
alternative to the requirements of this Standard, compliance with these instructions
generally ensures that—
(i) the material or product is fit for the application;
(ii) the performance of the system is not degraded;
(iii) the durability of the material or product is not impaired; and
(iv) the manufacturer’s warranty remains valid.
