Cold water leaks under your yard can cause big stress for homeowners. It means a hidden underground leak is wasting water and harming your property before you know it.
How to tell if you have a water leak underground? It’s simple. Look for soft, wet soil in areas that should be dry. Listen for water sounds when all taps are off. Watch for high water use without reason. These signs often point to a buried leak that must be found and fixed quickly.
Across Canada, about 17% of water produced is lost through leaks and breaks in distribution systems before it reaches homes and taps. This shows that underground leaks are common and can waste a huge amount of treated water if not found and fixed quickly.
In this blog, Blue Sea Plumbing will explore how to find a water leak underground.
How to Tell If You Have a Water Leak Underground
The following signs often show before major damage starts. A quick check can save water, money, and stress.
Sudden Increase in Water Bills
An underground leak can raise your water bill fast. This happens even when your daily use stays the same. Water flows below ground without notice and adds to the total use. Check your last two or three bills and see if there has been a jump in your bill for no clear reason. A large increase in your water bill can be a good indicator of a leak.
Wet Patches or Soft Soil in Your Yard
One green patch in a dry yard can mean trouble because extra water feeds grass in one spot only. This often means a pipe leaks under the soil.
Soft ground can also feel weak under your feet and may sink or feel spongy in places. These signs show water moves where it should not.
Low Water Pressure Inside the Home
This can happen because water escapes before it reaches the taps. You may feel a weak flow in showers or sinks. This often signals a hidden leak, and a plumber can test the system to confirm if there is a leak.
Sound of Running Water With Taps Off
Turn off all taps in the home and stand still to listen. A faint water sound can mean a leak underground. This sound often stays steady and does not stop. When you hear this, call for a plumbing inspection. Early plumbing repair can prevent major damage.
How to Find a Water Leak Underground
Take the following measures.
Meter Test You Can Do at Home
- Start by turning off all water use in the house.
- Make sure taps, showers, and appliances stay off. Then check the water meter.
- Write down the meter number. Wait one or two hours without using water.
- Check the meter again. If the number changes, a leak exists somewhere.
This test does not show the exact spot but confirms water loss. A plumber then finds the source with proper tools.
Visual Checks Around Foundation and Driveway
- Walk around your home and look near the foundation.
- Small cracks can form when soil stays wet for long periods.
- Check the driveway and paths.
- Sunken spots or uneven ground can point to water below.
- Pooled water near walls also signals trouble.
- Look inside basements or crawl spaces, too.
- Damp smells or wall marks can link to an underground pipe issue.
Why DIY Methods Often Miss Deep Leaks
Home checks only show surface clues. Delays raise repair costs and damage risk. Hidden leaks can weaken soil and pipes over time and lead to pipe breaks.
Blue Sea Plumbing usescamera inspections as well to make sure your pipes are not leaking.
How Does a Plumber Find a Water Leak Underground
Licensed plumbers use special tools to locate leaks below ground.
Acoustic Leak Detection
Plumbers use sound tools to hear leaks below the soil or concrete. Water under pressure makes a clear noise. The tool picks up that sound through the ground. This method works well for metal pipes and main water lines.
Thermal Imaging
Thermal cameras detect heat change under floors or soil. Water often stays cooler than dry areas. The camera shows this contrast on screen. This helps locate leaks under slabs or driveways.
Ground Sensors and Pressure Tests
Ground sensors read moisture levels below the surface. High moisture in one zone often signals a leak. Pressure tests check how the system holds water. A pressure drop confirms a leak. This test helps rule out false signs.
