Changes to AS/NZS 3500
Builders should be aware that major changes to AS/NZS 3500 will commence on 1 September 2022.
These include changes to elevated drainage pipework junctions which mean that all 100 mm branch drains will now be required to be installed at an inclination of not less than 15 degrees.
This may have major consequences to joist heights and bulkheads.
