From hidden leaks to burst pipes, let’s dive in and find out what could be driving up your water usage. By the end of this, we hope you’ll have a better idea of what’s happening and more importantly, how to fix it!

7 Potential Causes Behind High Water Bills

Let’s take a closer look at the most common factors that could be contributing to the increase. From hidden leaks to water-hogging fixtures – not only these triggers can waste tons of water, but it can also cause significant property damage. 

1. Underground Pipe Leaks

If you’ve noticed soggy patches in your yard or a sudden drop in water pressure, an underground water leak might be to blame. These leaks can go unnoticed for weeks, quietly wasting water beneath the surface. 

Furthermore, these leaks are tricky to spot without the proper tools, which is why many homeowners turn to a leak detection service.

Professionals use specialised equipment to locate leaks deep underground without digging up your entire yard. If left unattended, it’s likely you’d deal with a problem of high water bill due to a leak. 

2. Burst Water Pipe

One of the major causes for what causes water bills to be high is a burst water pipe. A burst pipe could flood your house in a matter of seconds, but sometimes smaller bursts can be harder to detect causing an eventual slow increase in water usage.

If it has been really cold around the house, or other potentially relevant external factors, that might be the reason.

Also, lookout for wet walls or ceilings or mysterious puddles since these tend to be indicators that a pipe in your home is broken.

Bursts can cause permanent and widespread damage throughout the rest of your home, so if it does happen to you, turn off your water supply pronto and ask a professional plumber to fix a burst water pipe before severe damage is done.

3. Leaking Mixer Tap

Wondering how to check if you deal with a  leaking mixer tap? Place a bowl under the tap overnight and see how much water it collects. If it’s filling up, it’s time for a quick fix.

Why does this happen? The rubber washers inside the tap can wear out over time, causing a poor seal.  Whether it’s a slow drip or a steady stream, a leaking tap is one of the easiest ways to run up your water bill without even realising it.

4. Leaking Toilet Base

An often overlooked source of wasted water is a leaking toilet base. This isn’t just about the water that’s visible on the floor—your toilet could be leaking from the base without you noticing, especially if the seal is old or damaged. This leads to continuous water running through your system, and yes, a high water bill.

If you notice dampness around the base of your toilet or hear running water long after flushing, it’s time to investigate. Replacing the wax ring or tightening the bolts holding the toilet in place can solve the issue, but if you’re unsure, getting help from a plumber might be your best bet. 

5. Running Toilet

A running toilet can waste hundreds of liters of water a day without you even realizing it. This issue often happens when the flapper valve inside the toilet’s tank doesn’t seal properly, causing water to continuously flow into the bowl.

If you hear water running long after flushing, it’s a clear sign that something’s wrong. A quick test: put a few drops of food coloring into the toilet tank and wait about 10 minutes. If you see the color in the bowl without flushing, you’ve got a leak!

6. Faulty Sprinkler System

A malfunctioning system could be to blame for your high water bill. Sprinkler lines can leak and timers may be set too long leading to above-average water usage. Many problems go unnoticed due to the fact that sprinklers are running at night when you’re not around.

Inspect your sprinkler heads for leaks and set timers properly to prevent over-watering. It’s better if you hire a professional to also check any hidden leaks. 

7. Inefficient Appliances

If you haven’t upgraded any old appliance in a while, this could be another factor behind your rising bills. You can swap your old items like dishwashers and washing machines with lower energy-efficient models.

Look for appliances with high water efficiency ratings. They not only reduce water usage but can lower your energy bills as well, making them a smart long-term investment.

Is Your Water Bill High All of a Sudden? Here’s What to Do

A significant increase in your water bill can be a frustrating situation, but the good news is that there are some simple steps you can take to figure out what’s going on—and fix it before things get worse.

First, check for any obvious leaks. Walk around your home and inspect faucets, toilets, and appliances for signs of water escaping. Even a small drip can lead to a surprisingly large increase in your water usage. Don’t forget to check your outdoor areas, too—hose connections, sprinkler systems, and garden taps are often overlooked sources of leaks.

Still can’t find the source? That’s why you need leak detection service! Sometimes leaks are hidden, like those in underground pipes or behind walls. A professional leak detection service can use advanced tools to pinpoint the problem without tearing up your home. If your water bill has shot up suddenly, this could be your best option for getting to the bottom of it quickly.

Lastly, consider whether there have been any recent changes in your household that might have caused an increase in water use—things like additional guests, changes in routine, or even seasonal watering habits. By systematically checking for leaks and evaluating your usage, you can get to the root of the problem and take action to bring your bill back down.
