In WA, under the Plumbers Licensing and Plumbing Standards Regulations, plumbing work can only be done by qualified people with a licence from the Plumbers Licensing Board. Plumbing work refers to work on water supply, sanitary, or drainage systems, including installation, alteration, repair, maintenance, testing, or replacement of pipes, fittings, fixtures, or apparatus used for water services. It excludes minor tasks like replacing a showerhead or clearing a blocked pipe, which homeowners can now legally do themselves under recent reforms.
