Pool Leak Detection for Marco Island
Find the source before water loss becomes a bigger problem
Marco Island pools sit on dredged fill a few feet above the canals, so a leaking line never leaves a puddle and often takes on groundwater when the pump is off, while the seawall side of every lot has been settling since the island was built and salt eats the fittings from the outside. If the autofill has been running or the summer water bill did not match an empty house, Blue Science finds the source and quotes the repair separately.
Fill settles toward the seawall and the tide moves the water table, so a Marco Island leak is read from two clocks: the tide chart, which tells us which side of the water table the line is on, and the seawall deck, whose settled corner tells us which skimmer joint to dye-test first.
Leak clues in a Marco Island pool
A level that holds at high tide and drops at low, a water bill that climbed while the house was empty, a coping joint that opened on the canal corner, air in the pump basket, or a light that quit after the level fell are the signs worth a call. The island is too wet to show a leak, so the pad and the pool have to tell the story.
Skimmer throats on settled seawall corners, corroded light niches and return fittings, and main drain lines below the water table are the usual sources, and each is dye-tested during the visit.

Questions Marco Island Pool Owners Ask
Can the high water table hide a leak?
It can change the reading. Groundwater pushing in from outside can slow a shell leak while the pump is off and let it run when the pump is on. That is why I test with the pump running and again with it off before I go looking for the spot.
Answered by a Blue Science leak technician, Southwest FloridaWhy is my pool losing 1 inch of water a day?
Three things drop a pool an inch a day, and only one of them is normal. Evaporation on the hottest Marco Island days can take up to half an inch, daily storms, Gulf salt air, and year-round use permitting; splash-out and backwashing take a little more on a busy weekend; everything past that is a leak. Pressure-side leaks show up as a wet spot or a pump that spits air, suction-side leaks as air in the pump basket, and shell leaks as a level that stops dropping at the same spot every time, which our leak detection visit sorts out with pressure tests and dye in any of the 17 cities we cover. Call 239-286-7700 before the autofill hides it: in Marco Island a leak that runs all summer costs more in water and chemicals than the visit that finds it.
How can I find out where my pool is leaking from?
You narrow it, we confirm it. The bucket test proves it is a leak; the stopping point of the water level narrows it to the skimmer, a return, the light, or the shell; and the pressure test on each line, with dye at the fittings, pins it down, daily storms, Gulf salt air, and year-round use or not. On a Marco Island pool that is usually a plumbing joint under the deck rather than a crack, and the visit ends with a written report of the source, the same report we write in all 17 cities. In Marco Island the visit starts at the equipment pad and works toward the shell, with daily storms, Gulf salt air, and year-round use in mind.
What is the easiest way to find a leak in a pool?
Compare the pool to a bucket. Fill a bucket to the pool level on the top step, mark both, run the pool normally for a day with the autofill off, and read the difference: evaporation moves both lines, a leak moves only the pool, whatever daily storms, Gulf salt air, and year-round use are doing. If a Marco Island pool loses more than the bucket, the next step is pressure testing the lines and dye testing the fittings to find where, the same steps in all 17 cities we serve. Turn the autofill off first in Marco Island, or the test measures nothing, whatever daily storms, Gulf salt air, and year-round use do.
What is the most common cause of pool leaks in Marco Island?
Movement. The deck and the shell move at different rates as daily storms, Gulf salt air, and year-round use work on a Marco Island yard, and every joint between them, the skimmer throat, the return fittings, the light niche, the spa spillway, is where a leak starts. Structural cracks are rare by comparison and easier to see, which is why the visit tests the joints first, in every one of the 17 cities we serve. Our Marco Island detection visit tests the skimmer and returns first because that is where the odds are, daily storms, Gulf salt air, and year-round use considered.
Where is the most common place for a pool leak to occur?
The skimmer, where the throat meets the shell, is the most common single spot, followed by the return fittings, the light niche and its conduit, and the main drain line, all of them worked on by daily storms, Gulf salt air, and year-round use. A Marco Island pool with an attached spa adds the spillway and the spa fittings to the list; each one shows a different pattern in the water level, and the dye test settles it in minutes once the level has narrowed the search, as it does across 17 cities.
