Has your water bill suddenly shot up, leaving you scratching your head and wondering what could be causing the unexpected spike?
A higher-than-expected water bill can be both frustrating and stressful. But when this happens, there are often a few common culprits that could be causing the excessive water consumption.
So, here are the most common reasons your water bill could suddenly skyrocket and tips on how to fix the potential problem.
Those pesky hidden leaks are the leading cause of any sudden increases in your water bill.
Such leaks can manifest in many different areas of your plumbing system, including pipes, toilets, fixtures, and underground water lines. Often, these leaks go unnoticed for longer periods of time, leading to substantial water waste.
Leaky Toilets
Toilets account for a significant portion of your home's water consumption, so it shouldn't come as any surprise that a leaking toilet can cause a significant increase in your water bill.
If you happen to notice your toilet has frequent flushing issues or has started to run longer than usual, it is time to seek the assistance of a professional plumber. A running toilet or a faulty flush valve could very easily be the reason behind your excessive water consumption.
Dripping Fixtures
Those seemingly minor drips coming from your taps and showerheads might not raise immediate concern, but they have the potential to waste a considerable amount of water over time.
Even a slow drip could translate to hundreds of litres lost each month, which obviously leads to a substantial increase in your water costs. Therefore, even these minor leaks should be addressed promptly.
Faulty Appliances
Some outdated appliances have the potential to consume unreasonable quantities of water, ultimately resulting in inflated bills.
Old dishwashers, washing machines, and refrigerators might lack the water-conserving components prevalent in many of their contemporary counterparts. If this is the case, it is worthwhile considering an upgrade to modern, energy-efficient appliances, as the transition can help reduce your water bill.
Faulty Irrigation Systems
For properties with an irrigation system, it is important to ensure it is running efficiently.
Damaged pipes, faulty valves, or leaks within sprinkler heads can lead to considerable water waste without you realising it. Regularly inspecting your irrigation system for leaks or damage is the best way to steer clear of these problems.
Hot Water System Problems
An outdated or damaged hot water system can quickly drive up water expenses. The buildup of sediments or a malfunctioning pressure relief valve can both result in leaks or excessive water consumption.
Should you detect any unusual sounds, irregular water temperatures, or any visible indication of a leak near your hot water system, it could be time for a repair or replacement.

Oct 12, 2026 Tom and Max did a wonderful job replacing the guttering at my house, repairing seized laundry taps, and removing an old insinkerator from my kitchen. I recommend them highly.

Oct 10, 2026 A big thank you to all the Jetset staff who worked on my property over the last 4 days. The team led by Rhys replaced my entire stormwater system, installed an undersink hot water system (love this!), fixed leaking taps and then replaced the electrics from the green box to my home. A massive effort by Rhys, Howie, Tom S, Winnie, Tom W, Luke, Kye, Sean, Josh, Liam, Hallsey and anyone i missed. Their professionalism and work ethic was incredible. Thank you for making a difficult process so easy.

Oct 08, 2026 Jack & Jacob have done an outstanding job on fixing the drainage around the majority of our house. The drainage issues have been a big concern for us and Jetset were the first people we called. Initially Doug talked us through a very comprehensive plan on how to fix our issues, and Jack & Jacob completed those plans to a great standard. Dealing with Doug, Jack and Jacob throughout the process has always been a pleasure.
Jack and Jacob were always on time and were always happy to stop and have a chat and answer all of our kids questions. We particularly appreciate the care and effort that was put into refurbishing the yard once the job had been completed. We had anticipated this job taking 4-5 days but Jack and Jacob completed it in 3 to a very high standard.
We have used Jetset multiple times now for both big and small jobs and we have never had anything but a great experience.

Oct 07, 2026 Excellent job by these two legends, Big T and Tye! They made us feel comfortable and reassured us that the job would be done properly, which was especially appreciated after what turned out to be a nasty main drain pipe/sinkhole.
Thanks to Jetset for the professionalism, perfection and great workmanship. You’ve got a fantastic bunch of guys! ??
