With over 38 years of experience serving Perth’s homes, I’ve learned that understanding plumbing regulations protects both your property and your family’s safety. As a licensed plumber, I’m often asked about what homeowners can legally do themselves versus when they need professional help.

Legal Requirements in Perth

Understanding Western Australian plumbing regulations is essential for every homeowner. Poor plumbing work can lead to contaminated water supplies, dangerous gas leaks, and significant property damage. These aren’t just guidelines – they’re legal requirements that carry serious penalties for non-compliance.

Work requiring a licensed plumber:

• Water supply connections – Any work involving your home’s water supply lines, including installing new taps or modifying existing pipework. This work requires licensing because incorrect installation can contaminate drinking water or cause major leaks.
• Drainage system modifications – This includes any changes to your home’s waste water systems, from adding new drainage points to repairing existing pipes. Licensed work ensures proper waste removal and prevents environmental contamination.
• Hot water system installation/repair – All work on hot water systems must be done by licensed professionals due to the combination of high pressure, high temperatures, and potential gas connections creating significant safety risks.
• Gas fitting work – Any work involving gas lines or appliances requires special licensing. The risks of gas leaks and explosions make this one of the most strictly regulated areas of plumbing.
• Sewerage connections – Work on sewer lines requires professional licensing to prevent health hazards and ensure proper connection to municipal systems.

Understanding DIY Possibilities

Water Corporation guidelines outline specific tasks that homeowners can safely perform. These tasks typically involve external components that don’t require direct interaction with water supply or drainage systems.

Permitted DIY tasks:

• Changing tap washers – You can replace worn washers in leaking taps after turning off the water supply. Ensure you use the correct size washer and can properly reassemble the tap. If you’re unsure, contact a professional.
• Clearing simple sink blockages – Basic sink or shower blockages can often be cleared using a plunger or removal of visible debris from the drain grate. Avoid using harsh chemicals that can damage pipes.
• Replacing shower heads – Shower heads can be changed by carefully unscrewing the old one and installing a new one with appropriate sealing tape. Ensure the connection is tight but not over-tightened.
• Installing water-efficient aerators – These simple devices screw onto tap spouts to reduce water flow. Make sure they’re compatible with your tap type and properly sealed.
• Basic tap cleaning – Regular cleaning of tap surfaces and aerators helps prevent buildup and maintains proper flow. Use appropriate cleaning products and avoid damaging chrome finishes.

Safety First

Even with permitted DIY tasks, safety must be your primary concern. Only licensed professionals should handle work involving water supply, gas, or major plumbing modifications.

Essential safety measures:

• Water supply location – Know where your main water shut-off valve is located and test it periodically. This knowledge is crucial for stopping water flow in emergencies.
• Electrical hazard awareness – Never work on plumbing near live electrical connections. If you have any doubts about electrical safety, contact a licensed electrician.
• Proper tools – Use the correct tools for each job. Makeshift solutions often lead to injuries or damaged plumbing.
• Clean workspace – Keep your work area clean and well-lit. Remove trip hazards and ensure good access to the work area.
• Emergency contacts – Have professional plumbing contacts ready before starting any DIY work. If problems occur, quick professional response can prevent major damage.

Emergency Response

When plumbing emergencies occur, knowing what you can legally do helps prevent further damage while waiting for professional help.

Permitted emergency actions:

• Water supply shut-off – Immediately turn off the water supply if you discover a major leak. Know both local fixture shut-offs and main water valve locations.
• Basic leak containment – Use buckets or towels to contain water from active leaks. Move valuable items away from affected areas to prevent damage.
• Surface water removal – Remove standing water to prevent damage to floors and walls. Use mops, towels, or wet vacuums as appropriate.
• Damage documentation – Take photos and notes about the damage for insurance purposes. Document when the problem started and what immediate actions you took.
• Professional contact – Call a licensed plumber as soon as possible. Explain the situation clearly and follow any immediate advice they provide.

Professional Work Requirements

Licensed plumbing work includes several key components that ensure safety and reliability:

• Proper permits – Professional plumbers obtain necessary permits and ensure work meets all local codes.
• Quality materials – Licensed plumbers use approved materials that meet Australian standards.
• System knowledge – Professional work considers how changes affect the entire plumbing system.
• Safety compliance – Licensed work includes proper safety measures and testing.
• Documentation – Professional plumbers provide required certificates and warranties.
