━ WARNING SIGNS
Signs of an Underground Water Line Leak
An underground water line leak rarely starts with a visible puddle. Water from a buried service line soaks into the soil first, so the earliest signs appear at the water meter, on the water bill, and in the lawn.
- Water Meter Moves With Everything Off: The low-flow indicator on the water meter keeps turning after every faucet, toilet, and appliance in the home is shut off.
- Unexplained High Water Bill: The water bill rises even though household water use has not changed.
- Wet or Unusually Green Strip in the Yard: Soggy soil or greener grass forms along the path between the curb and the house.
- Low Water Pressure Throughout the Home: Every fixture loses pressure at the same time because water escapes before it reaches the house.
- Settling Soil or Small Sinkholes: A long-running leak washes soil away and leaves a depression above the buried pipe.
Sprinkler systems run on separate zones, so a soggy lawn near sprinkler heads usually calls for irrigation leak detection rather than a service line inspection.

━ WHAT WE DETECT
Where Underground Water Line Leaks Develop
A residential water service line in Bensalem runs underground from the curb stop, through the water meter, and into the home. Leaks form at predictable weak points along that path.
Corroded Service Pipe
Older copper and galvanized steel service lines corrode over time, and corrosion eventually opens pinhole leaks along the buried pipe.
Failed Fittings and Couplings
Fittings and couplings join sections of the service line, and a loose or cracked fitting releases pressurized water into the surrounding soil.
Curb Stop and Meter Connections
The curb stop valve and the connections at the water meter hold constant pressure, and worn seals at these points leak continuously.
Damaged Pipe at the Foundation Entry
The service line enters the home through the foundation, and settling at this entry point can crack or bend the pipe.
━ HOW IT WORKS
How Underground Leak Detection Works
Leak Detection Bensalem follows a step-by-step process that confirms the leak, separates the service line from the plumbing inside the home, and marks the exact leak location on the ground.
01
Confirm Water Loss at the Meter
The technician reads the water meter with every fixture off to confirm that water is leaving the plumbing system.
02
Isolate the Service Line
Closing the main shutoff valve separates the service line from the interior plumbing. If the meter stops, the leak is inside the home, and slab leak detection or an indoor inspection is the next step.
03
Trace the Pipe Route
Pipe locating equipment maps the path of the buried line between the curb stop and the house.
04
Pinpoint the Leak
Acoustic equipment listens along the mapped route for the sound of pressurized water escaping from the pipe.
05
Mark the Repair Spot
The technician marks the leak location on the surface so the repair contractor can open one small area instead of the full line.
━ ADVANCED DETECTION TECHNOLOGY
Underground Leak Detection Methods and What They Reveal
Each detection method answers a different question about the buried line. Leak Detection Bensalem combines these methods to confirm the leak location before any digging begins.
Water Meter Testing
Meter readings taken with all fixtures off confirm that water is leaving the service line and show how fast the loss occurs.
Pipe Locating
Pipe locating equipment traces the route of the buried service line, so the leak search follows the actual pipe instead of a guess.
Acoustic Leak Detection
Acoustic listening equipment amplifies the sound of water escaping from a pressurized pipe, and the sound is strongest near the leak.
Isolation Testing
Isolation testing separates the service line from the interior plumbing and confirms which section of the system is losing water.
Why Early Underground Leak Detection Matters
An underground water line leak runs continuously, and every gallon passes through the water meter before it escapes into the soil. The property owner pays for that lost water on every bill until the leak is found.
A long-running leak also washes soil away from the pipe and can undermine walkways, driveways, and the ground near the foundation. Finding the exact leak location early keeps the repair small and limits excavation to one spot.
━ Common Issues
Frequently Asked Questions
These answers cover the questions Bensalem homeowners ask most often about leaks in a buried water service line.
Still Have Questions?
How do I know if my water line is leaking underground?
A water meter that keeps moving while every fixture is off is the clearest sign of a leak. If the meter still moves after you close the main shutoff valve inside the home, the leak is on the underground service line. Our water meter leak test guide explains each step.
Who is responsible for a leak in the water service line?
Aqua Pennsylvania generally maintains the pipe from the water main to the curb stop, and the property owner maintains the service line from the curb stop to the home. Aqua Pennsylvania can confirm ownership for a specific address. Our guide to water service line ownership explains the difference.
Do you have to dig up my whole yard to find the leak?
No. Leak Detection Bensalem pinpoints the leak before excavation, so the repair crew opens one small area above the leak instead of trenching the full length of the line.
Can an underground leak cause a high water bill?
Yes. Every gallon that escapes from the service line passes through the water meter first, so an underground leak raises the water bill even when no water is visible. Our article on why a water bill suddenly rises covers other causes to rule out.
Is an underground water leak the same as a sewer line leak?
No. An underground water leak comes from the pressurized supply line that brings clean water into the home, while a sewer leak comes from the drain line that carries wastewater away. Drain-side problems call for sewer line leak detection.
NEED PROFESSIONAL LEAK DETECTION?
Find the Leak in Your Underground Water Line
A moving water meter and a wet strip of lawn confirm that water is escaping, but they do not show where. Leak Detection Bensalem traces the buried line, pinpoints the leak, and marks the spot so the repair stays small. Call (877) 540-5737, Monday to Sunday from 8 AM to 8 PM, or book online to request your inspection.
