Water Line Leak Detection in Hillsborough, NJ

Locate underground service line leaks accurately without destroying your entire yard.

The Main Service Line Challenge

The main water line runs underground from the municipal meter at the street directly into your home. In Hillsborough areas like Neshanic, where properties can be set far back from the road, this means a long expanse of buried pipe. When this line leaks, a homeowner is responsible for repairs, and finding the leak's exact location in a large yard can be daunting.

Warning Signs of a Water Line Leak

Unexplained puddles or unusually lush patches of grass in your yard, even during dry weather.
A severe, sudden drop in water pressure throughout your house.
A water meter that spins constantly when no water is being used indoors.
Dirt or sediment appearing in your tap water.
A sinkhole forming near the foundation.

Local Causes

New Jersey's freeze-thaw cycle shifts the ground, stressing rigid pipes. Invasive tree roots seeking moisture can crush or penetrate older water lines. Note: NJ requires water utilities to replace lead service lines, so if you have an older property, a leak might prompt a full line replacement. Often, what appears to be an irrigation issue is actually a water line or pool leak.

Our Step-by-Step Detection Method

Meter Verification: We check the meter to confirm the leak is indeed on the main line between the street and the house.
Line Locating: We safely trace the underground path of your water pipe using electromagnetic utility locators.
Acoustic and Tracer Gas: We listen for the leak underground. If it's too quiet, we can pressurize the line with a safe, inert tracer gas and use sniffers to find where it escapes the ground.
Marking: We mark the precise spot for the repair crew.

What Happens After the Leak is Found?

Once pinpointed, the required excavation is kept to an absolute minimum—often just a single hole rather than a massive trench across your landscaping. You'll know exactly what type of pipe leak repair is needed before any digging begins.

Cost Factors to Consider

Repair costs are influenced by the depth of the pipe, the ground cover (e.g., grass vs. a concrete driveway), and whether the pipe material is salvageable or if a full line replacement is necessary.

Prevention Tips

Avoid planting large trees with aggressive root systems near the path of your water line. Be aware that before any digging or excavation happens for repairs, you must call NJ One Call (811).

Frequently Asked Questions

Who is responsible for the main water line?

In most municipalities, the homeowner is responsible for the line from the water meter (usually at the curb or street) to the house.

How does tracer gas work?

We empty the line of water and fill it with a harmless mix of nitrogen and hydrogen. Because hydrogen is light, it escapes through the leak and rises through the soil, where our sensors detect it.

Can you fix a leak under a concrete driveway?

Yes, we can find it. If it is under concrete, we treat it similarly to slab leak detection, minimizing the concrete removal needed.
