Why a Clean, Clear Pool Is Important for Leak Detection

When performing a pool leak detection, it’s important that the pool is filled to its normal operating level — ideally with the water level at the middle of the tile line — and that the water is clean, clear, and warm.
These conditions allow for the most accurate visual testing and dye detection results.

Finding Leaks in Green or Cloudy Pools

Of course, not every pool is in perfect shape when a technician arrives. Sometimes the water is cloudy or green, which can make locating leaks much more difficult — and in some cases, not worth attempting.

If the pool water is too green to see through, visual leak detection becomes unreliable, and there’s a higher risk of missing leaks or damaging equipment. In such cases, it’s often best to reschedule the appointment and have the homeowner treat and clear the pool first.
Even though it may feel like a delay, this ensures an accurate inspection and protects both the pool and the technician.

Why Green Pools and Leaks Often Go Hand in Hand

It’s common for leaking pools to turn green, since the constant addition of untreated water makes it almost impossible to maintain proper chemical balance.
If clearing the pool before testing isn’t possible, there are still a few methods that can help:

• Look for algae-free spots on the surface — the water movement from a leak often clears algae around the source, making it easier to identify.

• Use electronic detection tools like LeakTrac or hydrophones, which can locate leaks without needing to see through the water.

• Perform pressure testing and pipe leak location when visibility is too poor for dye testing.

• Always clean your equipment thoroughly afterward and use protective gloves when handling plugs in algae-covered water.

Setting Realistic Expectations

If a leak detection must be performed on a green pool, it’s important to be upfront about what to expect.
Limited visibility can affect efficiency and accuracy, so customers should understand that results may be impacted and that service time will still be billed.

At Carlito’s Way Pool Leak Detection, I always aim for complete transparency. The best results come when the pool is clear, clean, and properly filled, but I also have the tools and experience to handle less-than-perfect conditions when necessary.
