How to Identify, Prevent, and Fix Water Leaks in Your Home
Water leaks are one of the most common household plumbing problems — and one of the easiest to overlook. A single dripping tap can waste over 5,000 litres of water in just three months, increasing your water bills and putting unnecessary strain on Melbourne’s water system. Detecting leaks early not only saves you money but also protects your property from structural damage and mould growth.
🔍 How to Check for Water Leaks
Here’s a simple test you can do yourself:
Turn off all water sources inside and outside your home — taps, showers, toilets, washing machines, sprinklers, and garden hoses.
Locate your water meter, usually near the front boundary of your property. Record the numbers displayed on the dials.
Wait 30 minutes without using any water.
Check the meter again. If the numbers have changed, it means water is flowing somewhere — and you likely have a leak.
For the most accurate results, do this test when nobody is home and appliances are off.
🚿 Common Sources of Household Water Leaks
Leaks can occur almost anywhere in your plumbing system. The most frequent culprits include:
Leaking taps and mixers – often caused by worn washers or O-rings.
Running toilets – a faulty cistern valve can waste hundreds of litres daily.
Burst or corroded pipes – especially in older homes with galvanised or copper lines.
Hot water systems – leaks around valves or tanks are warning signs of failure.
Underground leaks – these can cause damp patches in lawns or driveways.
Appliance connections – washing machines, dishwashers, and fridges with water lines can loosen over time.
If you hear running water when all taps are off, notice damp patches, mould, or a sudden spike in your water bill, it’s time to call a licensed plumber.
🧰 Preventing Future Water Leaks
Preventing leaks is all about maintenance and early detection:
Inspect taps, toilets, and visible pipes monthly.
Replace ageing plumbing fixtures before they fail — new taps and valves are more water-efficient.
Check flexible hoses (under sinks and behind washing machines) for bulges or corrosion every 12 months.
Install water-efficient fixtures that carry the WaterMark certification and WELS rating.
Service your hot water system every 3–5 years to avoid pressure or valve leaks.
Use a licensed plumber for installations and renovations to ensure compliance with AS/NZS 3500 plumbing standards.
