waterleak underground

A water leak can happen at any time especially underground. If it does happen, it can cause a lot of problems if not detected early enough.

You can always hire a professional plumber to detect it but you should find your own DIY ways to detect underground water leak effortlessly.

What Causes Underground Water Leaks

A few things have been known to cause underground water leaks. These include:

  • Water Or Soil Chemicals – The pipes found underneath your house may crack or break due to the chemicals found in water or soil.

These chemicals make the pipes erode causing cracks or holes that leak water into the soil underneath your home or the slab in the basement.

  • Earth Tremors And Natural Disasters – This can shift the ground and put a lot of pressure on the water lines.

Eventually, the water pipes will crack and the water will start moving the soil underneath the slab.

As a result, your property could become a very unsafe place to live because of the health concerns and structural issues caused by earth tremors and natural disasters.

How To Detect Underground Water Leak

1. Check Your Water Meter

Do you feel like there is a leak happening underneath your house?

Start by turning off all the water including faucets, tank toilets, washing machines and so forth.

Next, you should check the water meter dial to see its current position then wait for half an hour before checking it again.

If there is any change in position, it’s a sign there is a water leak that needs fixing.

Keep in mind that underground water leaks might be rare but can happen.

For instance, they can happen if the ground levels in the basement were raised during construction, especially using filled in soil.

2. Check The Water Bill

You should check your water bill regularly to determine if there is an underground leak.

If you have been using a steady amount of water each month in your home and you notice an increase the next month, there is a water leak somewhere.

Make sure your water bill is based only on the water passing through the meter.

When you notice such a change, it’s a good idea to hire plumbing experts to do an inspection and confirm this for you.

3. Check Your Property

If there is any underground water leaking, you should be able to notice the leaks when you check your property.

For instance, are there random pools of water on the property? Are there any lush spots in the yard? Do you smell something musty in your home? Is there any mould growing in your house?

Any of these indicators are a sign there is a leak that needs to be attended to immediately.

What To Do When You Notice A Leak

Firstly, you need to contact a professional plumber to handle any underground water leaks.

If you don’t have the expertise to fix everything on your own, hiring a plumber is a very good idea.

Of course, you need to do your research and due diligence to find the right plumber for the job.

Secondly, you should know that not all underground leaks will be from the water supply. They might be caused by defective drain lines or the sewer.

The professional should help you determine where it’s coming from. Remember, underground leaks often start small.

Therefore, it’s a good idea to catch them early before they cause any property damage.


Plumbing professionals have the right tools to determine whether or not there is an underground water leak.

If you have used the methods above to check for a leak and have found one, then you need to hire a professional for the best repair results.
