Advisory Notes

 Advisory Notes

Pressure Control Valves - The purpose of this Advisory Note is to provide technical information to the plumbing industry on the terminology and use of pressure control valves used in water services installed in accordance with AS/NZS 3500:2003. The majority of these valves are used where the pressure service exceeds 500 kpa and when an authorised pressure regulating device is required. 

PN16 Cross Linked Polyethylene Pipes and Fittings - The purpose of this Advisory Note is to advise that plastic pipe and fittings including PN16 Cross Linked Polyethylene (PE-X) are suitable for use in water services where the pressure supplies from the property service exceeds 500 kpa and when an authorised pressure regulating device is installed. 

Polyethylene and Polypropylene Elbows - The purpose of this Advisory Note is to provide guidance to the Australian and New Zealand plumbing industry and consumers that the installation of Polyethylene and Polypropylene elbows in Sanitary and Drainage gravitational installations is unsatisfactory. 

Solvent Cement Welding - The purpose of this Advisory Note is to provide advice to the plumbing industry on a national basis regarding the current practise of jointing Unplasticised Polyvinyl Chroride (PVC-U) sanitary plumbing and drainage products to either Acrylonitrile Butadiene Styrene (ABS) or Acrylic Styrene Acrylonitrile (ASA) and similary ABS/ASA to PVC-U sanitary plumbing and drainage products by solvent welding. As this has become common practice using Type N solvent cement in non pressure applications and although not currently referenced in AS/NZS 3500:2003 it is recognised by regulators as acceptable industry practice.

Waterless Urinals - The purpose of this Advisory Note is to provide guidance to the Australian and New Zealand plumbing industry and consumers regarding the installation and maintenance of waterless urinals.

ASFlow - The purpose of this Advisory Note is to inform industry, government agencies and consumers of the current research being conducted to investigate the effect of reduction of wastewater flows, in particular those from sanitary plumbing fixtures, on the performance of plumbing and drainage systems.
