DIY Plumbing in Victoria: What You Can (and Can’t) Do Yourself
Will we or wont we enter into a recession in Australia this year? Whether we do or not, one thing is certain; the cost of goods and services has increased significantly this year and everyone is trying to reduce their spending and DIY as much as possible. When you have a plumbing issue and funds are tight, the thought of a DIY fix might seem appealing. However, in Victoria—and across Australia—plumbing is a licensed trade, meaning there are strict rules about what you can and cannot do yourself. Attempting jobs outside of your legal ability can not only create further issues but also land you in hot water with the law, and with your insurance provider if things go wrong.
What DIY Plumbing Jobs Can You Legally Do in Victoria?
We’ve spoken at length about who can legally complete plumbing tasks in Victoria; including the difference between licensed and registered plumbers, and what tasks handymen can complete.
What we haven’t talked about is what DIY plumbing tasks can be completed without the use of a licensed plumber if you’re handy on the tools.
There are a few straightforward tasks you’re allowed to handle on your own without the need for a licensed plumber. These include:
- Clearing drains using a plunger
- Connecting a washing machine hose
- Cleaning and maintaining external drain traps and grates
- Clearing blocked gutters or downpipes
- Turning your water supply on and off
- Checking your water meter
While the list of DIY plumbing jobs you can legally perform without a licensed plumber is limited, there are still steps you can take to maintain your system and avoid bigger issues.
What DIY Plumbing Jobs Are Illegal in Victoria?
In Victoria, the plumbing industry is regulated by the Victorian Building Authority (VBA). It does this to ensure the health and safety of Victorians is protected, and also the integrity of our water supply and wastewater systems is maintained. It mandates that any work on sewer or drinking water systems must be carried out by a licensed plumber. This prevents unlicensed individuals from attempting more complex plumbing tasks that could lead to health risks, property damage, or legal consequences. The jobs that must be performed by a licensed plumber all fall under ten main classes of plumbing work in Victoria, here is a breakdown:
- Drainage (e.g. Installing or repairing underground sewer pipes to connect a house to the main sewage system).
- Fire Protection (e.g. Installing and maintaining sprinkler systems in a commercial building to meet fire safety regulations).
- Gasfitting (e.g. Installing a residential gas hot water system, including connecting it to the existing gas supply).
- Irrigation (Non-agricultural) (e.g. Setting up a garden irrigation system for residential landscaping, including drip lines and spray heads).
- Mechanical Services (e.g. Installing ductwork and ventilation systems in a commercial building to control air distribution and indoor air quality).
- Refrigerated Air-conditioning (e.g. Installing a split system air-conditioning unit in a home, including refrigerant piping and electrical connections).
- Roofing (Stormwater) (e.g. Installing downpipes and guttering on a roof to direct stormwater away from a building and prevent flooding).
- Sanitary (e.g. Installing or repairing a bathroom’s waste pipes, such as those connected to a toilet or sink).
- Type B Gasfitting (e.g. Installing a large commercial gas burner or boiler used in industrial settings for heating or steam generation).
- Water Supply (e.g. Installing a new cold and hot water supply system for a residential home, including the connection of taps and appliances).
These examples highlight the diversity of tasks within the plumbing profession, with each class requiring specific skills and licensing.
Do Plumbing Regulations Differ by State?
Yes, plumbing regulations can vary across Australia’s states and territories. For example, while you can legally do your own bathroom waterproofing in Victoria, it is illegal in Queensland and New South Wales. In Western Australia, it’s an open market for roofer however in Victoria you need a roofing (stormwater) class license as part of your plumbing license. Before you embark on any DIY plumbing work, it’s essential to check the specific regulations in your state to avoid any costly mistakes.
What Happens if You Break Plumbing Laws in Victoria?
If you choose to disregard Victoria’s plumbing laws and undertake unlicensed work, you risk severe consequences. These can affect both you and your property:
- Your appliance warranties will become void
- Insurance claims for damages caused by unlicensed work will be rejected
- You’ll be responsible for the cost of repairing any damage caused
- You could face fines of up to $32,000 under the Plumbing and Drainage Act (although these fines are usually given to unlicensed tradies rather than DIYers)
- You may experience difficulties or delays when selling your property, as uncertified alterations or additions may come to the attention of a building inspector and will need to be rectified.
A licensed plumber can provide a compliance certificate to ensure that all work meets legal standards and avoid future issues.
