Pool Leak Detection in New Jersey & Staten Island
Think your pool is leaking? Whether it’s your plumbing, pool structure, or underground lines, accurately identifying the source of water loss requires more than a visual inspection.
Atlantic Pool Leak Detection provides advanced, non-invasive leak detection services throughout New Jersey and Staten Island, NY. Using specialized diagnostic equipment and proven testing methods, we locate leaks precisely – without unnecessary digging or guesswork.
Protect Your Pool Investment with Accurate Leak Detection
A swimming pool is a major investment. When leaks go undetected or are misdiagnosed, they can lead to costly damage, wasted water, and unnecessary repairs.
Our team specializes in identifying the exact source of leaks so repairs can be targeted, efficient, and effective.
Whether you’re a homeowner, pool professional, or property manager, we help get to the root of the problem quickly — so your pool can return to normal operation.
What Causes a Pool Leak?
Pool leaks can develop in several areas, and each requires a different approach to properly diagnose:
- Underground plumbing line breaks
- Vinyl liner punctures or seam separation
- Cracks in gunite or fiberglass shells
- Failing fittings (skimmers, returns, lights)
- Structural movement or settling
Because leaks can occur in multiple locations at once, proper testing is critical to avoid incomplete or incorrect repairs.
Common Signs Your Pool May Be Leaking
Not all water loss is a leak – but these are strong indicators that your pool may have a problem:
- You are frequently adding water
- Air bubbles are visible in the pump or system loses prime
- Cracks in the pool shell, tile, or coping
- Pool deck shifting, sinking, or heaving
- Wet or soggy areas around the pool
- Increased chemical usage
If you’re noticing one or more of these signs, further testing is recommended.
Where Do Pools Leak Most Often?
Leaks commonly occur in the following areas:
- Skimmers – A common leak point due to separation between the skimmer body and the concrete or liner.
- Return lines – Often develop leaks underground from shifting soil or pipe stress.
- Main drain lines – Can crack or even separate underground and are not visible without pressure testing.
- Pool lights and conduits – While the light fixture itself can leak, in many cases the leak originates in the conduit line that runs underground behind the light niche.
- Underground plumbing – Breaks or separations can occur outside the pool structure and are one of the most commonly missed leak sources.
- Vinyl liners – Holes, tears, or seam separations can develop over time, especially in high-use or older liners.
Some of these leaks are visible, while others – especially underground plumbing leaks require specialized equipment to locate.
How Pool Leak Detection Works
Proper pool leak detection is not a single test, it is a structured process of elimination designed to isolate and confirm the exact source of water loss. At Atlantic Pool Leak Detection, we evaluate each component of the pool system individually, including the structure, fittings, and plumbing lines, to determine where the leak is actually occurring.
Our process may include:
- Pressure Testing – Plumbing lines are isolated and tested to determine if they are holding pressure. This allows us to identify underground pipe leaks that are not visible from the surface.
- Electronic Leak Detection – Specialized listening equipment is used to detect leaks inside and beneath the pool and surrounding areas, including underground pool plumbing.
- Dye Testing – Used to confirm leaks in visible areas such as liners, fittings, skimmers, and light niches.
- Line Isolation Testing – Helps narrow down exactly which section of plumbing is compromised, eliminating unnecessary guesswork or exploratory digging.
Rather than relying on assumptions, this methodical approach allows us to confirm whether the leak is in the pool structure, the plumbing system, or both.
We We routinely find leaks that were previously overlooked or misdiagnosed
In many cases, pool leaks are misdiagnosed because the visible issue is not the true source of the problem.
We routinely find leaks that were previously overlooked or misdiagnosed – including underground plumbing breaks, conduit leaks behind pool lights, and pressure-related failures that cannot be identified through visual inspection alone.
Most homeowners assume the leak is where they see damage, such as a liner tear, cracked fitting, or wet area. However, in many situations, proper testing reveals the actual issue is occurring elsewhere within the system.
Our process is designed to eliminate guesswork by systematically testing each component of the pool (when necessary), allowing us to isolate and confirm the exact source of water loss before any repairs are made.
This is the difference between simply finding a leak and finding the right leak.
Why Many Pool Leak Detections Miss the Real Problem
Many pool owners initially hire divers or rely on visual inspections. While these approaches may identify obvious issues, they are limited to what can be seen.
| Feature/Capability | Scuba Only | Atlantic Pool Leak Detection (Full Diagnostics) |
| Underwater shell inspection | Yes | Yes |
| Visual inspection of fittings & lights | Yes | Yes |
| Detects cracks in plaster / liner | Yes | Yes |
| Detects leaks in skimmer lines | No | Yes |
| Detects leaks in return lines | No | Yes |
| Detects leaks in main drain lines | No | Yes |
| Detects underground plumbing leaks | No | Yes |
| Line isolation testing | No | Yes |
| Confirms plumbing integrity | No | Yes |
| Can rule out plumbing system | No | Yes |
| Finds leaks not visible to divers | No | Yes |
| Non-invasive diagnostics | Limited | Yes |
| Provides objective test results | No | Yes |
This is why relying on visual inspection alone often results in missed leaks and incomplete repairs. In some instances, a complete leak detection service is required, performing both visual AND diagnostic testing to ensure no leaks are missed.
The Cost of Misdiagnosing a Pool Leak
Many pool owners attempt to fix leaks based on assumptions — patching liners, replacing fittings, or even cutting into plumbing without confirming the true source of the problem. In many cases, the actual leak remains undetected, leading to repeated repairs, unnecessary work, and significantly higher long-term costs. Proper leak detection is not just about finding a leak — it’s about finding the right leak before any repairs begin.
What Can Happen If a Pool Loses Too Much Water
In some cases, prolonged water loss can lead to serious structural issues, especially if a pool is left empty or nearly empty for an extended period of time.
We have seen situations where pools lost significant amounts of water over the winter without the homeowner realizing it due to the pool being covered. When the pool was opened in the spring, water levels had dropped dramatically.
In one case, a concrete (gunite) pool actually shifted and “popped” out of the ground by nearly 24 inches due to hydrostatic pressure from groundwater.
Water inside a pool helps counterbalance external pressure from the surrounding soil and groundwater. When that water is lost, the structure can become vulnerable to movement, damage, or even complete failure.
This is why identifying and addressing leaks even during the off-season is critical.
Types of Pool Leak Detection We Perform
We provide leak detection for all pool types and systems:
- Vinyl liner pools
- Gunite / concrete pools
- Fiberglass pools
- Pool plumbing systems
- Underground pipe leaks

Can a Pool Lose Water Without a Leak?
Yes – pools naturally lose water due to evaporation. Factors such as temperature, wind, humidity, and sun exposure can impact water loss.
However, excessive water loss may indicate a leak.
💡Pro Tip
If you find yourself adding water more than once or twice a week, there is a strong chance your pool may have a leak and should be professionally evaluated.
If you’re unsure, we recommend performing a bucket test or reviewing our guide on pool leak vs evaporation to help determine if further testing is needed.

Frequently Asked Questions
How much water loss is normal in a pool?
Most pools lose approximately 1/8” to 1/4” per day due to evaporation. Anything significantly above this may indicate a leak.
Do I need to drain my pool for leak detection?
No! Almost all leak detection services are performed with the pool filled.
How long does leak detection take?
Most leak detection services can be completed in a couple of hours, depending on the complexity.
Can a pool leak come and go?
Yes, there are times when a pool leak may appear inconsistent. This can occur when leaks are pressure-related and only happen while the system is running, or when the water level drops below the leak point. Sometimes a hole or tear can be “clogged” with dirt or debris which temporarily stops the leak until the debris is dislodged. As a result, the leak may seem to stop temporarily, even though the underlying issue is still present.
Are underground leaks common?
Yes, underground plumbing leaks are one of the most common and often require specialized testing to locate.
Can an underground pool leak wash out soil?
Yes, underground leaks can erode soil over time, which may lead to voids beneath the pool deck or surrounding areas. This can cause settling, cracking, or structural movement if left unaddressed. Identifying and repairing underground leaks early helps prevent more extensive damage.
Are pool leaks worse in the winter?
Pool leaks are not necessarily worse in the winter, the issue is that they often go unnoticed. When pools are covered and not in use, water loss can continue for months without being detected. In some cases, pools may lose a significant amount of water over the winter, which can lead to potential damage to the pool cover, liner, or structure.
