Leak Detection Explained

Why Non-Invasive
Leak Detection Matters.

Traditional leak detection meant tearing into walls, floors, and ceilings just to find the source of a leak โ€” expensive, disruptive, and often wrong on the first try. GO2 Plumber uses acoustic listening equipment and infrared thermal imaging to locate leaks behind walls, under slabs, and inside pipe systems without any demolition. In most NYC apartments and pre-war buildings, we can pinpoint the exact leak location in under an hour.

Leaks in NYC buildings commonly come from a few sources: aging galvanized supply lines corroding from the inside, slab leaks under concrete foundations, deteriorated joint seals in cast iron drain stacks, and pinhole leaks in copper pipe from water chemistry issues. Each type requires a different detection approach, which is why we start with a full visual and acoustic assessment before recommending a fix โ€” repair when possible, replacement only when necessary.

Left undetected, even a small leak can lead to mold growth, structural damage, and inflated water bills. If you're seeing unexplained water stains, a spike in your water bill, or a musty smell that won't go away, it's worth having a licensed plumber run leak detection before the damage spreads. We frequently run leak detection in pre-war buildings throughout Washington Heights and Crown Heights, where original plumbing is most likely to be the source.

Detection Methodology

How Professional Leak
Detection Works.

Beyond the equipment used, here's the actual methodology behind finding a hidden leak:

1

Inspect

We check the affected area and surrounding systems โ€” visible plumbing, recent water usage patterns, and secondary damage like staining or warping that hints at the source.

2

Detect

Acoustic and thermal equipment narrow the search from "somewhere in this wall or floor" down to a specific, mapped area โ€” without opening anything up yet.

3

Locate

Once the general area is identified, we pinpoint the exact leak point โ€” the specific joint, fitting, or pipe section โ€” so any access work that follows is targeted, not exploratory.

4

Diagnose

Finding the leak is only half the picture. We also determine the underlying cause โ€” age-related failure, a bad connection, freeze damage, or something else โ€” since that determines whether a spot repair or a broader fix is the right call.

Every Leak Source

Types of Leaks
We Detect.

Different leaks hide in different places โ€” and need different detection methods.

01

Slab Leaks

Water lines running under a concrete foundation. Acoustic detection locates these without breaking up the slab to search โ€” see Water Line Replacement if the line needs full replacement rather than a point repair.

02

Supply Line Leaks

Behind walls or under floors, usually from aging or corroded pipe. Thermal imaging finds the exact point before we open anything โ€” see Pipe Repair & Repiping for the fix once located.

03

Drain & Sewer Line Leaks

Deteriorated joints or cracked sections in a drain stack or sewer line, often showing up as odor or slow drainage before visible water โ€” see Sewer Line Service for camera inspection and repair.

04

Appliance & Fixture Leaks

Failing supply connections at water heaters, dishwashers, and washing machines. If the source turns out to be the unit itself, see Water Heater Repair.

05

Overhead & Neighbor-Unit Leaks

Common in NYC multi-unit buildings โ€” water coming from the apartment above. We coordinate with building management to trace the source and document findings for co-op boards โ€” see Apartment Building Plumbing.
