Finding a water leak underground can be tricky. Often, you won’t know that you’ve got a leaking underground pipe until you get an unusually high water bill (we’re talking 50% more or even higher). That’s a lot of money! That being said, there are other signs that you can watch out for, such as water pooling in an area on your property. 

We’ve previously talked about what causes a burst water pipe, but in this article, we are going to delve into the nitty-gritty of how to find an underground water leak. Not only will we show you a few simple tests to help you self-diagnose the problem at home, but we will walk you through how a professional plumber can help locate and identify the exact location of the leak and, in turn, fix the problem once and for all.

How to figure out if you’ve got a burst underground pipe

Now, we’ll walk you through a few simple steps to help you determine whether or not you have a burst underground pipe. 

Step one: locate your water meter

A water meter measures the amount of water entering your house. It is usually located in the nature strip outside your property, in a black or green box. 

Bear in mind if you live in a complex with other units, apartments, or townhouses, there may not be an individual water meter for each dwelling. If you suspect a water leak in this situation, the best course of action is to contact body corporate or simply contact a professional plumber yourself. 

Step two: turn off all taps and any appliances that use water 

Be very thorough with this step; things like the freezer making ice can be enough to throw the readings off, so check everything. 

Step three: make a note of your water meter reading

This will help you know the baseline at which you’re starting. 

Step four: do not use any water for at least one hour

This includes flushing the toilet! Really be mindful of trying to keep the results as precise and reliable as possible. If you end up using any water before taking your second reading, simply start again from step two. 

Step five: after one hour, take a new meter reading. If the number has changed, you have a leak 

Once the hour has elapsed, and if you didn’t use any water during that period, it’s time for a second reading. Sadly, if the new reading is higher than the first, you have a leak. (Top tip: we recommend you perform this process regularly in order to catch leaks early and save you money in the long run – a burst underground pipe can be extremely expensive). 

If you can’t find the location of the leak, then you should contact a professional plumber to get it diagnosed and fixed as soon as possible. 

How To Determine the Location of an Underground Leak

Different methods might be employed when determining the exact location of an underground leak. We always strive to use the least invasive approach. Whilst we can provide basic initial inspections, a professional leak specialist might need to be called in if the leak is hard to locate. Let’s take a look at a few leak detection methods:

Physically examining the plumbing

The first step we take when attempting to identify the exact location of a leak is to walk around the property and check all internal and external plumbing for any signs of a leak, such as dripping water, damp areas, and pools of water. If we cannot identify a leak like this, we will bring in a leak detection specialist who may use any of the following methods. 

Gas injection method

This method involves adding pressurised gas into your pipes. The gas will then seep out at the leak location, and the leak specialist will use specialised equipment to detect traces of the gas. This should provide enough evidence of where the problem is located and is best for leaks occurring under hard materials such as concrete. 

Acoustic leak detection

Leaks make noise, and with this technique, specialised equipment that can pick up faint sounds is used to determine the location of the leak. 

As you can see, identifying an underground leak is no easy feat and can require some serious equipment and can cost a lot of money if left unattended. So if you suspect you’ve got a leaking pipe, contact us now.
