How Find Hidden Water Leaks Plumbing

Do you suspect that you have a hidden water leak? If so, do you know how to find it? If this sounds like you, we’re here to help provide you with the answers. Water leak detection is critical if you want to save money and prevent consequential disasters.

Therefore, there are a few steps that you can take if you suspect that there is a hidden water leak in your property. You might be wondering: what are these steps?

In this article, we explore six ways that you can find a hidden water leak. They are as follows:

  • Read your water meter
  • Monitor your water bill
  • Grab some food colouring
  • Check your home’s exterior
  • Look for other telltale signs
  • Contact your plumber

1). Read Your Water Meter

Reading your water meter is one of the best ways to determine hidden leaks. The first step in carrying out this process is to check your water meter and take down the numbers. Next, turn off all faucets in your home. Make sure that your dishwasher and your washing machine are not running. 

Come back to your water meter. If you notice a change in the numbers already, then you may have a fast-moving leak. If you do not notice any sudden changes, wait for an hour or two before checking the water meter again (ensuring that all faucets are off). If there are changes, then you may have a slower leak.

2). Monitor Your Water Bill

Gather up your water bills from the past few months and compare them to determine if there has been a steady increase. Generally, your water bill should remain within the same range month to month if your water use habits are consistent. 

If you notice that your water bill has been rising even though your water use habits have not changed significantly, then this may be due to a hidden leak. It is best to call a plumber so that they can investigate what the problem may be.

3). Grab Some Food Colouring

If you suspect that you have a hidden water leak in your toilet, then food colouring is the solution for you. To test for water leaks in your toilet, drop some food colouring into your toilet tank and wait for around 10 minutes.

If you find that some of the colouring shows up in your toilet bowl, then there is a leak flowing from the tank to your drain without needing to be flushed.

4). Check Your Home’s Exterior

Hidden leaks can occur both inside and outside your home. Therefore, it is important to check exterior usage as well. For example, if you find that there are out-of-place puddles or damp spots in the ground this can be an indication of an existing link.

5). Look For Telltale Signs

Sometimes, actively looking for telltale signs will help you detect a hidden leak. Check under basins, walls, or cabinets if there are any signs of mould or foul smells. Make sure to inspect all water connections for oxidation or discolouration, which can be a sign of a slow leak.

6). Contact Your Plumber

Whether you were able to detect a hidden leak or not, it is critical that you contact a plumber especially before potential damage is caused. When a leak is not fixed in its early stages, this can lead to serious consequences such as structural damage and overall safety problems. Therefore, contact your plumber so that they can prevent damage and any further issues from occurring.


Hidden water leaks are no joke. It is important to take hidden water leaks seriously before serious damage takes place. Some ways you can detect a hidden leak include reading your water meter, monitoring your water bill, grabbing some food colouring, checking your home’s exterior, looking for other telltale signs and of course, contacting your plumber whether you were able to detect the hidden leak or not.
