Water and Sewerage Regulation 2001

The following requirements are prescribed:

for domestic water supply plumbing work involving the installation of, or work on, a shower—the shower head must have a maximum flow capacity of not more than 9L per minute;

for domestic water supply plumbing work involving the installation of, or work on, a tap for a kitchen or laundry sink or any other basin inside a building—the outlet of the tap must have a maximum flow capacity of not more than 9L per minute.

The maximum flow capacity mentioned in subsection (1) must be worked out using AS/NZS 6400 as in force from time to time.

Note AS/NZS 6400 does not need to be notified under the Legislation Act because s 47 (5) and (6) do not apply (see Act, s 44D). The standard may be purchased at www.standards.org.au.

Subsection (1) (b) does not apply to domestic water supply plumbing work involving the installation of, or work on, a tap for a kitchen or laundry sink or any other basin inside a building if—

the tap is in part of the building used, or for use, mainly for business; or

the usual pressure of water that is, or is to be, supplied to the building is less than 50kPa.

Example

a home on a farm supplied with bore water at a pressure less than 50kPa
