Why Is My Water Bill So High? Common Causes in Brisbane
Brisbane residents pay some of the highest water rates in Australia. If your latest bill is unexpectedly high, there could be a hidden plumbing issue costing you money every day. Here are the most common causes.
Running Toilets
A constantly running toilet can waste up to 60,000 litres of water per year — that's over $200 added to your annual bill. Often the issue is a worn-out flapper valve or a faulty fill mechanism, both of which are inexpensive to fix.
Dripping Taps
A single dripping tap wastes around 20,000 litres per year. It might seem minor, but multiply that across several taps in your home and the costs add up fast. Most dripping taps just need a new washer or cartridge.
Hidden Leaks
Leaks behind walls, under slabs, or in underground pipes are the most expensive water wasters because you can't see them. Signs include damp patches on walls, unexplained mould, or a water meter that keeps ticking when everything is turned off.
How to Check for Hidden Leaks
Turn off all taps and appliances in your home, then check your water meter. If the dial is still moving, you have a leak somewhere. Note the reading, wait two hours without using any water, and check again. Any change confirms a leak.
Outdated Fixtures
Older Brisbane homes often have outdated taps, showerheads, and toilets that use far more water than modern WELS-rated fixtures. Upgrading to water-efficient fixtures can reduce household water use by up to 30%.
Faulty Hot Water System
A leaking hot water system not only wastes water but also wastes energy heating water you never use. Check the pressure relief valve on your system — a small but constant drip here can waste thousands of litres annually.
