If you’re a homeowner, there’s a good chance that you’ll experience a leaking water pipe at some point. While it’s never a pleasant experience, it’s important to take action quickly to prevent further damage.
If the leak is underground, it can be even more challenging to detect and repair. In this guide, we’ll provide you with some tips on how to fix a leaking water pipe underground.

First, it’s important to identify the location of the leak. Look for signs of wet spots or puddles in your yard or driveway, as this can indicate the general area of the leak.
You can also check your water meter to see if it’s still running even when all the taps in your home are turned off. If the meter is still running, this could be a sign of a leak.
Once you’ve identified the location of the leak, it’s time to dig down to the pipe. This can be a challenging and time-consuming process, so be prepared to put in some effort.
Use a shovel to carefully dig around the area where you suspect the leak is located. Be careful not to damage the pipe further as you dig. But if you are not confident doing this kind of work, just call Leak Detection Warragul.
Once you’ve exposed the pipe, you can begin to assess the damage and determine the best course of action.
Identifying and Locating the Leak
Initial Inspection and Safety Precautions
If you suspect a leaking water pipe underground, the first step is to perform an initial inspection of your property. Look for wet spots, damp spots, and mildew growth on your walls, ceilings, and floors.
Check your water bill for any unexpected increase in usage that may indicate a leak.
Next, locate your water meter and check the spinning indicator. If it’s moving when no water is being used, this may be a sign of a leak.
Check for any recessed or swelling ground around the area where the water main enters your property. This could also indicate an underground water leak.
Before attempting to locate and fix the leak, it’s important to take safety precautions. Turn off your water supply at the shutoff valve to prevent any further damage to your property.
If you’re unsure about how to do this, contact a licensed plumber to assist you.
Understanding Ownership and Responsibility
When it comes to fixing a leaking water pipe underground, it’s important to understand ownership and responsibility.
The water main that supplies water to your property is typically owned and maintained by your local water authority. However, the pipes that run from the water main to your property are usually the responsibility of the property owner.
If you suspect a leaking water pipe underground, it’s important to determine who is responsible for fixing it. Contact your local water authority to confirm ownership and responsibility.
If the leaking pipe is on your property, you will need to hire a licensed plumber like Leak Detection Warragul to locate and fix the leak.
Repairing the Leaking Underground Pipe
When you have a leaking underground water pipe, it’s important to take immediate action to prevent further water damage, mold growth, and higher water bills.
While you can hire a professional plumber to fix the leak, you can also do it yourself with the right tools and materials. Here’s what you need to know to repair the leaking underground pipe:
Preparing for the Repair
Before you start digging, you need to locate the leak by following the sightline from the water meter to your home. Look for wet spots or low water pressure in your faucets to identify the damaged area.
Once you’ve located the leak, you need to obtain any necessary zoning or permits to perform the excavation and repair.
To prepare for the repair, you will need the following tools and materials:
- Shovel or spade
- Tarp
- Sandpaper
- Hacksaw
- Copper, PVC, or PEX pipe (matching the diameter of the damaged pipe)
- Fittings and connectors
- Pipe cutter or similar tool
- Water pressure gauge
Executing the Repair
To execute the repair, you will need to dig a trench around the damaged pipe, taking care to avoid any potable water lines or easements.
Once you have exposed the damaged pipe, you can cut out the leaking section using a pipe cutter or similar tool.
Be sure to cut the replacement pipe to match the length of the damaged section, and use fittings and connectors to attach it to the existing plumbing system.
After you have completed the repair, test it by running water through the pipes and checking the water pressure gauge for any abnormalities.
Sand the edges of the new pipe and fittings to ensure a tight seal, and cover the trench with soil and landscaping materials.
Post-Repair Considerations
It’s important to monitor the repaired area for any signs of water damage or mold growth.
If you notice any issues, contact a professional plumber to inspect the repair and ensure that it was done correctly.
Additionally, be aware of any tree roots or other potential causes of future leaks.
Take precautions to prevent structural damage to your yard, driveways, or patios.
