Pipe Sizing Calculator — AS/NZS 3500 Compliant
Calculate pipe sizes per AS/NZS 3500 standards. Input fixture units, flow rates, and pipe material to get the correct diameter for Australian plumbing installations.
This tool uses the fixture-unit and pipe-size lookup tables from AS/NZS 3500.1 (water supply) and AS/NZS 3500.2 (sanitary drainage). Results include clause references so you can verify against the published Standard.
