VBA Update February 201811 January 2018
AMENDMENT No. 1 to AS/NZS 3500.2:2015
The Victorian Building Authority (VBA) reminds plumbing practitioners carrying out sanitary plumbing and drainage work to familiarise themselves with Amendment No.1 to AS/NZS 3500.2:2015 Plumbing and drainage Part 2: Sanitary plumbing and drainage that was published by Standards Australia 30 June 2017.
The amendment specifies that:
- The connection of any drain to a graded drain either above or below ground shall only be made with a junction with an upstream angle not greater than 45° degrees
- Sweep or square junctions may however, still be used, such as at the top of a jump up, at the connection of a branch drain to a boundary trap riser or as an inlet connection to a gully riser
- Square junctions shall be used at the connection of an inspection shaft to a graded drain or as inspection openings.
The amendment is designed to ensure the free-flowing function of sanitary drains and was introduced after consideration of industry feedback. Plumbing practitioners must comply with this amendment in their plumbing work.
