Tracer Gas Detection:
What is Tracer Gas Leak Detection?
Tracer Gas Leak Detection is an advanced, non-invasive method used to locate hidden water leaks with high precision. This process involves injecting inert tracer gases (Hydrogen/Nitrogen) into a pipeline, plumbing system, or void, where the gas escapes through the leak. A gas sniffer then detects the escaping gas as it rises to the surface, accurately pinpointing the leak location.
Where Can Tracer Gas Leak Detection Be Used?
🔹 Central heating leaks – Identify leaks in radiators and heating systems
🔹 Roof leaks – Locate hidden roof leaks with precision
🔹 Underfloor leaks – Detect leaks beneath concrete, tiles, and flooring
🔹 Wall & cavity leaks – Find leaks inside walls without invasive methods

Water Leak Pressure Testing:
What is Pressure Testing?
Pressure testing is a highly effective and accurate method for detecting leaks in various pipe systems, including central heating, underfloor heating, mains supply, and hot and cold water pipes. This method involves pressurizing the pipework to a level up to 1.5 times its normal working pressure (depending on the pipe type and condition) and then monitoring for any pressure loss.
📉 A drop in pressure? → Indicates a leak is present.
📈 Pressure holds steady? → Confirms no leaks in the system.
How Does Pressure Testing Work?
1️⃣ Pressurization. 2️⃣ Monitoring. 3️⃣ Leak Confirmation.
4️⃣ Leak Location & Repair.
5️⃣ Final Verification – After repairs, a second pressure test is performed to ensure the repair is secure and there are no additional leaks.
UV / Dye Testing Leak Detection:
What is Leak Detection Dye?
Leak Detection Dye is a highly effective, non-toxic, and water-soluble dye designed to trace and identify water leaks in pipework, bathrooms, ceilings, flat roofs, toilets, drains, swimming pools, voids, and cavities. This specialist dye technology allows us to visually confirm water escapes without causing any damage to your property.
How Does Leak Detection Dye Work?
1️⃣ Dye Application – Our highly concentrated leak detection dye is introduced into the suspected water source.
2️⃣ Leak Tracking – As water flows through leaks or damaged areas, the dye visibly highlights the escape points.
3️⃣ Precise Identification – Our leak detection specialists analyze the results to pinpoint the exact source of the leak.
Moisture Meter Leak Detection:
What Are Moisture Meters?
Moisture meters, also known as damp meters, are essential tools used to detect hidden leaks and assess water damage in buildings. These devices accurately measure moisture levels in walls, floors, and ceilings, helping to trace internal water leaks and structural damp issues.
How Moisture Meters Help in Leak Detection
🔹 Identify hidden water damage.
🔹 Trace internal leaks
🔹 Assess water damage severity
🔹 Prevent mold growth
Underground Pipe Locator:
Know What’s Beneath Before You Dig!
Before you break ground on your next project, do you know what’s hidden beneath the surface? Failing to accurately locate underground utilities can result in costly repairs, hazardous accidents, and major project delays.
From water and sewer lines to gas pipes and electrical cables, a single mistake can cause serious safety risks and expensive disruptions.
At First Class Leak Detection, we provide expert utility locating services in New Jersey, delivering precise, data-driven underground mapping to help you avoid potential hazards and keep your project on schedule and within budget.

Sewer Camera Locator:
Get to the Root of Your Sewer Problems – Without the Guesswork
Your sewer drains play a crucial role in directing water and waste safely away from your home. But when problems arise—slow drainage, bad odors, or recurring blockages—you need a fast, accurate diagnosis to avoid costly repairs.
How do you determine the exact cause of your sewer line issues? A sewer video inspection is the most effective way to identify the root of the problem without unnecessary digging or disruption.
How Does a Sewer Video Inspection Work?
Using state-of-the-art, high-resolution cameras, our trained technicians insert a specialized waterproof sewer camera into your pipes. This allows us to:
🔹 Detect tree root intrusion, grease buildup, and pipe misalignment
🔹 Assess overall pipe health
Smoke Test Leak Detection:
Accurate Leak Detection Without Breaking Ground
One of the most effective and non-invasive methods for detecting leaks is smoke testing. This process involves injecting artificially produced smoke into pipelines to identify leaks, blockages, and structural issues.
If a pipe is in good condition, the smoke will exit through manhole covers as expected. However, if there are cracks, breaks, or leaks, the smoke will emerge in unexpected areas, allowing us to pinpoint the exact location of the problem.
How Does Smoke Testing Work?
1️⃣ Smoke Injection – A safe, non-toxic smoke is pumped into the pipeline.
2️⃣ Leak Identification – The smoke travels through the system, revealing cracks, leaks, and faulty connections.
3️⃣ Accurate Diagnosis – Our specialists analyze the smoke patterns to determine where repairs are needed.
Borescope Camera Leak Detection:
Detect Hidden Leaks Without Unnecessary Damage
Endoscopic leak detection is a highly effective and minimally invasive method for locating hidden water leaks inside hollow walls, recesses, and confined spaces. By using a small, flexible camera with built-in lighting, our specialists can access tight spaces and visually inspect your plumbing system in real time without the need for large openings or demolition.
Where Is Endoscopic Leak Detection Used?
🔹 Inside Walls & Ceilings.
🔹 Tight Plumbing Spaces.
🔹 Industrial & Commercial Buildings.
🔹 Pre-Repair Inspections.
Correlation Leak Detection:
Pinpoint Leaks with Advanced Acoustic Technology
Correlation Leak Detection is a highly accurate and non-invasive method used to locate leaks in pressurized water pipes. When a pipe leaks, it generates a distinct sound that travels along the pipe’s material. Using specialized sensors and advanced algorithms, we can precisely determine the exact location of the leak without unnecessary excavation or disruption.
How Does Correlation Leak Detection Work?
1️⃣ Sensor Placement.
2️⃣ Sound Transmission & Recording.
3️⃣ Data Processing
4️⃣ Mathematical Analysis.
Acoustic Location of Plastic Pipes:
Locating Pipes with Precision Using Acoustic Vibration Technology
Finding underground pipes—especially non-metallic pipes like plastic and fiber cement—requires specialized detection methods. Traditional electromagnetic detection cannot locate non-conductive pipes, making acoustic pipe location the most effective solution.
By using a battery-powered Stopper piston at a fire hydrant, we can control vibration intensity and set the water column in motion. The resulting vibrations travel through the pipe and into the surrounding soil, allowing us to accurately locate the pipeline using ground microphones.
Applications of Acoustic Pipe Location
🔹 Locating Plastic Water Mains – Identify non-conductive pipelines that cannot be found with electromagnetic detection.
🔹 Fibre Cement & Metal Pipe Detection – Effective for multiple pipe materials.
🔹 Municipal & Utility Infrastructure – Ensuring precise mapping of underground water distribution networks.
🔹 Leak Detection Enhancement – Helps confirm pipeline paths before performing acoustic leak detection.
