Large custom pools can contain numerous pumps, suction lines, returns, drains, spa functions, water features and specialty fittings. Complex pools require a very systematic process to ensure time and money is not wasted looking for a leak in the wrong place.
We provide complete swimming pool leak detection in Colts Neck, New Jersey. Our testing may combine scuba inspection, dye testing, individual plumbing-line pressure testing and electronic or acoustic locating of confirmed underground breaks.
Atlantic Pool Leak Detection is a father-and-son company operated by Randy and Ryan Racioppi. With more than 15 years of leak detection experience and thousands of pool leaks located, this specialized work is our primary service throughout Colts Neck, Monmouth County and surrounding New Jersey communities.
A Real Colts Neck Case: A Complex New Pool That Continued Losing Water
A pool builder contacted us about a newly constructed gunite pool and attached spa in Colts Neck. The pool was approximately 1,200 square feet and was losing about 1.5-2 inches of water per day. With five pumps and roughly 15 plumbing lines, the system was considerably more complex than a standard residential pool.
The builder’s crew had attempted to plug the pool and reported that it continued losing water. When we evaluated the system, we found several openings, including wall and bottom drain lines, that had not been plugged. This meant the pool had not actually been fully isolated.
We identified nine accessible plumbing lines that still required testing and pressure-tested each one individually. All nine lines held pressure. That result was important: it ruled out failures in the nine plumbing lines we tested, but it did not prove that the entire pool was watertight.
We then tested the pool underwater by getting in the pool with scuba gear on. Dye testing showed water being drawn into the wall fitting for one of the nicheless pool lights. The leak appeared to be in the PVC conduit behind the light (underneath the pool deck).
With the builder’s knowledge and approval, we disconnected the light, pulled the cable and plugged the wall fitting to stop the pool from leaking.

What This Colts Neck Case Demonstrates
- “Everything was plugged” is not a test result. Every opening and line must be identified and verified.
- Pressure testing can rule out failed plumbing lines, but it does not locate structural, fitting or conduit leaks that are outside the tested lines.
- Large custom pools require methodical testing because numerous pumps and lines create more possible failure points.
- Scuba inspection and dye testing remain essential even when every tested plumbing line holds pressure.
- Disabling an individual light and plugging its wall fitting may stop the leak, but it also removes that light from service.
Why Complex Pools Require a Line-by-Line Plan
A five-pump pool/spa combo will have more plumbing lines that what would be considered standard or normal. If the lines are unlabeled or only some openings are plugged, it becomes difficult to know what has actually been isolated. We begin by identifying accessible lines and documenting what will be tested, plugged or evaluated underwater.
Testing should also be interpreted by scope. Nine passing pressure tests confirm that those nine lines held under the test conditions. They do not establish that every wall fitting, light conduit, structural opening or untested circuit is watertight.
Pressure Testing and Underwater Testing Answer Different Questions
Pressure testing evaluates whether an isolated plumbing line can maintain pressure. Scuba inspection and dye testing evaluate accessible underwater areas such as lights, fittings, skimmers, drains and structural openings. Neither method replaces the other on a complex pool.
In the Colts Neck case, the plumbing lines held pressure, but dye still showed active water movement at a light fitting. Stopping after the pressure tests would have left the actual leak unresolved.

How We Approach Complex Pool Leak Detection
- Document the system: We identify pumps, operating modes, accessible plumbing lines, drains, lights, fittings, spa functions and water features.
- Verify prior isolation: We confirm which openings are actually plugged rather than relying on a general statement that the pool was isolated.
- Pressure-test individual lines: Accessible plumbing lines are tested separately so each result has a defined scope.
- Inspect underwater areas: Scuba and dye testing evaluate structural openings, lights and fittings that plumbing pressure tests do not.
- Interpret results together: Lines that pass a pressure test may narrow the investigation to certain possibilities, but further testing must be done to determine the cause of the water loss.
- Explain corrective options: We distinguish repair, temporary sealing and permanent feature abandonment, including what will no longer operate.
- Monitor the result: The owner or builder should monitor the water level and report continued loss because multiple leaks can exist.
Pool Leaks We Locate in Colts Neck
- Gunite and concrete structural openings
- Pool-light fittings and PVC light conduits
- Skimmers, returns, drains and specialty fittings
- Individual underground plumbing lines
- Attached spa and water-feature systems
- Vinyl liner and fiberglass pool leaks
- Multiple simultaneous leaks in complex pool systems
More Than Just a Pool Diver
This case also shows why the best service is not “diving only” or “pressure testing only.” Scuba and dye testing found the light-conduit leak, while pressure testing ruled out nine plumbing lines. Complete leak detection uses the methods required by the pool and interprets them together.

Frequently Asked Questions About Pool Leak Detection in Colts Neck
Can a pool still leak if every plumbing line passes a pressure test?
Yes. A pool may lose water through a light conduit, fitting, skimmer, structural opening, liner or another area outside the tested plumbing lines. Passing pressure tests define what was ruled out; they do not prove the entire pool is watertight.
Can a pool light cause water loss?
Water may escape through the wall fitting or PVC conduit that carries a nicheless light cable away from the pool. The light fixture itself may still operate, so the complete light assembly and surrounding fitting must be evaluated.
Why would a pool-light conduit leak?
Possible causes include a damaged conduit, failed connection, movement, installation conditions or an incomplete seal. The exact failure may not be visible without access. Dye testing can confirm an active leak at the pool-side fitting.
Does plugging a light fitting permanently disable the light?
Yes. If the cable is removed and the wall fitting is securely plugged, that light is taken out of service. This should be done only with the owner or builder’s authorization and with a clear understanding of the result.
How do you test a pool with many pumps and plumbing lines?
We identify the system components, determine what can be isolated, test accessible lines individually and inspect underwater openings that are not covered by plumbing pressure tests. Complex systems may require additional time.
Can a newly built pool leak?
Yes. New construction does not guarantee that every plumbing connection, fitting, conduit or structural opening is watertight. The source still needs to be confirmed through appropriate testing.
Do you need to drain the pool before testing?
No. The pool should normally be filled to its regular operating level so scuba inspection, dye testing and water-loss comparisons can be performed.
Do you serve all of Colts Neck?
Yes. We provide residential in-ground pool leak detection throughout Colts Neck and nearby Monmouth County communities. Appointment availability varies by season.
