Pool Leak Detection for Captiva
Find the source before water loss becomes a bigger problem
Captiva pools sit on barrier-island sand that drains a leaking line straight down, in salt air that eats the light niches and fittings from the outside, and most of them go months without an owner looking at the tile line. 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.
With nobody home, the autofill hides the leak and the water bill reveals it, so we start a Captiva call by reading what the fill line did over the summer, then pressure test each line on its own and dye-test the corroded fittings nearest the Gulf before the shell.
Leak clues in a Captiva pool
A water bill that climbed while the house was empty, an autofill that never rests, air in the pump basket, a light that quit after the level fell, or a level that tracks the tide on the channel side are the signs worth a call. Island sand drains the loss away instantly, so a wet spot in the yard is never part of the picture.
Corroded light niches and return fittings on the Gulf side, skimmer throats on the older Captiva Drive pools, and main drain lines below the water table along the channel are the usual sources, and each is dye-tested during the visit.

Questions Captiva 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?
It is almost certainly a leak. Evaporation in Captiva peaks around half an inch a day in a dry, windy heat wave and drops to almost nothing in humid weather, so an inch a day, every day, means water is leaving through the plumbing or the shell, whatever daily storms, Gulf salt air, and year-round use are doing. The clue is where the level stops: at the skimmer, the skimmer or a return is the suspect; below the lights, look at the light niche or the main drain line; all the way down, the shell has a crack, and 239-286-7700 gets the test scheduled. Our Captiva leak detection visit starts at the equipment pad and works toward the shell, with daily storms, Gulf salt air, and year-round use in mind, and repairs are quoted separately once the source is found.
How can I find out where my pool is leaking from?
Watch the level, then test the lines. Mark the waterline, turn off the autofill, and note where the pool settles over a day or two, the skimmer mouth, the return fittings, the light niche, and the main drain each showing a different stopping point, whatever daily storms, Gulf salt air, and year-round use are doing. What you cannot see from the deck, a Captiva leak detection visit finds by pressure-testing each line and dye-testing the fittings and the shell, the same routine across 17 cities. In Captiva 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?
The bucket test. A bucket on the top step, filled to the pool's level and marked, loses water only to evaporation, daily storms, Gulf salt air, and year-round use included; the pool loses water to evaporation and to any leak. Compare the two lines after 24 hours with the autofill off and the gap is the leak; in Captiva that takes a day and no tools, and finding the source takes the pressure and dye testing of a detection visit, one call to 239-286-7700. The bucket test is also how our Captiva technicians check the repair afterward, against daily storms, Gulf salt air, and year-round use.
What is the most common cause of pool leaks in Captiva?
Fittings and plumbing under the deck, worked loose by daily storms, Gulf salt air, and year-round use. Skimmer throats separate, return lines crack where the deck settles, and light conduit corrodes in wet ground; in a Captiva pool, under daily storms, Gulf salt air, and year-round use, all three are more common than a crack in the shell. Because they hide under the deck, the search runs under pressure, line by line, rather than by eye, which is what the team at 239-286-7700 is set up for. Our Captiva 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.
Can a pool leak be in the plumbing under the deck?
Often it is, and daily storms, Gulf salt air, and year-round use make it likelier. Suction lines from the skimmer and main drain and the return lines to the jets all run under the deck, and they are the lines a shifting Captiva deck stresses most as daily storms, Gulf salt air, and year-round use work on it; pressure testing isolates each line and shows which one will not hold, and locating equipment narrows the break to a spot before anything is opened. Detection and repair are quoted separately, so you approve a defined fix rather than a search, the same way in all 17 cities.
