What a plumber actually does

Plumbers move between residential, commercial and service work. New-build plumbers turn up to construction sites for rough-in, doing drainage, water supply, gas-fitting and roof drainage. Once the trades clean up, plumbers come back for fit-off, installing fixtures, sanitaryware, hot-water systems and gas appliances. Service plumbers run from a van doing leak repairs, blocked drains and hot-water replacements. Most days start around 7am and run to 3.30pm or 4pm. Once you are licensed, you can sign off your own work to AS/NZS 3500 and the National Construction Code. Like electricians, many plumbers move into running their own business after 5-10 years. There are several licence endorsements in plumbing including gas-fitting, drainage, roofing, mechanical services and water plumbing.

Typical tasks

  • Install pipework and fixtures to AS/NZS 3500 series standards.
  • Conduct compliance inspections and pressure tests.
  • Diagnose and repair leaks and blockages.
