You don’t need a licensed plumber for unregulated plumbing and drainage work. However, it must meet the minimum standards and comply with any codes and legislation.
Unregulated work includes:
- replacing a shower head or domestic water filter cartridge
- replacing a jumper valve or washer in a tap
- repairing or replacing a drop valve washer, float valve washer, or suction cup rubber in a toilet cistern
- replacing caps to ground level inspection openings on a sanitary plan
- cleaning or maintaining a ground level grate for a trap on a sanitary drain
- installing or maintaining an irrigation or lawn watering system downstream from a tap, isolating valve, or backflow prevention device on the supply pipe for the watering system
- repairing or maintaining an irrigation system for the disposal of effluent from a greywater use facility or onsite sewage facility.
