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Some outdated appliances have the potential to consume unreasonable quantities of water, ultimately resulting in inflated bills.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An outdated or damaged hot water system can quickly drive up water expenses.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.

Aug 05, 2026 I called Jet Set Plumbing for my place in Varsity Lakes and Reece came. Reece was amazing. He went above and beyond. I called to just look at the downpipe but he inspected the sewage, the taps inside the house and provided a full comprehensive assessment - without me even asking. After everything he called much later to even check in to ensure everything was okay. I would recommend Jet Set Plumbing and Reece to everyone. Amazing customer service - the best.

Aug 04, 2026 After buying our first home, we had a wide variety of plumbing works needing to be done, and quickly. We saw the Jetset team and the overwhelmingly positive google reviews and went with the crowd. Boy are we glad we did.
This team has blown my socks off with how excellent their service and professionalism is. From start to finish, they provided clear and consise information about each job they completed, and did amazing work all the way along.
To top it off, we recieved a lovely little gift in the mail a month after all was completed, that we use every day.
Can't thank the team enough for their work and would encourage anyone to use Jetset in the future.

Jul 31, 2026 I’d like to thank Mitch of GC Jetset Plumbing for the excellent and meticulous workmanship, professionalism, prompt and on time service. Mitch showed willingness to share his knowledge and expertise for me to understand the job at hand and was up front and committed to his quote, start to finish. My weekend will be spent swanning past my bathroom to stare at my new toilet system and enjoy the peace of no running water , overflow or hissing 😂 Thank you Mitch and thank you Jetset Plumbing for your prompt service response.

Jul 27, 2026 I recently had Jetset Plumbing replace my hot water system, and I couldn't be happier with the service. Communication was excellent from start to finish, and Tom took the time to clearly (and kindly) explain the issues with my electrical system in a way that was easy to understand. The whole team was friendly, professional, and efficient. I highly recommend Jetset Plumbing, and a big thank you for the thoughtful surprise gift—it was such a lovely touch!

Jul 17, 2026 Jetset plumbing upgraded my 18 year old failing hot water system. Liam was assigned the job of replacing the system. He was very professional, polite and kept me informed of his progress. His workmanship was excellent and he left the site clean and tidy. Prior to completing the job he explained the key maintenance tasks that I needed to do every six months to ensure the system functioned optimally.
