High Water Bill but No Leaks? Here’s What Could Be Going On
Opening your water bill shouldn’t feel like a jump scare—but for many Aussie homeowners, it does. If your bill’s creeping up and you can’t see any obvious leaks, you’re not alone. The bad news? Water can disappear quietly. The good news? There’s always a reason—and a fix.
Let’s break it down.
Why Your Water Bill Is High (Even When Nothing’s Leaking)
If your usage doesn’t match your lifestyle, something’s off. Common culprits include:
- Hidden leaks inside walls or underground
- Toilets that run silently after flushing
- Ageing pipes or fittings
- Hot water systems releasing excess pressure
- Outdoor or garden line leaks
These issues don’t announce themselves. They just quietly rack up your bill.
The Most Common Hidden Leaks Homeowners Miss
Toilets
A worn valve can cause constant refilling—no noise, no puddles, just wasted water.
Pipes Behind Walls
Cracks or loose joints can leak for months before showing damage.
Underground Pipes
Often found under driveways or gardens, these leaks are invisible but costly.
Hot Water Systems
Pressure relief valves can discharge water continuously without you noticing.
How to Check for a Water Leak Using Your Water Meter
You can do this quick check yourself:
- Locate your water meter (usually near the front boundary)
- Turn off all water in the house
- Watch the low-flow indicator on the meter
- If it moves, water is flowing somewhere—it shouldn’t be
That tiny spinning wheel is brutally honest.
Signs You Might Have a Hidden Leak
Keep an eye out for:
- Unexpected bill spikes
- Damp patches or mould
- Hissing or dripping sounds
- Toilets that keep refilling
- Warm patches on floors
If more than one shows up, don’t ignore it.
When to Call a Local Plumber
If your meter indicates a leak and you can’t find it, it’s time to call in the pros. Licensed plumbers have the tools to detect leaks inside walls or underground—without ripping your place apart.
Delaying repairs doesn’t save money. It burns it.
