Pool Leak Detection for Carrollton
Water loss has a source; find it before it becomes a bigger problem
Carrollton pools have plumbing that has outlived its expected life, buried in blackland clay that swells every wet spring and shrinks every August drought. If your pool is losing more than evaporation explains, Blue Science finds the source and quotes the repair separately.
Half the Carrollton leak calls are summer evaporation, and the bucket test sorts that out in a day. The other half are real, and on an original 1980s pool the first place we look is the skimmer throat and the light niche, not the shell.
Leak clues in an older Carrollton pool
Air in the pump basket, a level that drops faster with the pump running, a deck slab that has lifted or dropped at a joint, a soft spot in the yard, or a jump in the water bill are the signs worth a call. Clay movement opens skimmer-to-shell joints and return fittings, and tree roots in Rosemeade and Indian Creek find any gap in original PVC.
Old light niches and skimmer throats are the usual sources, and each is dye-tested during the visit.

Questions Carrollton Pool Owners Ask
How do I know it is a leak and not the weather?
Put a bucket of pool water on the step for a day and mark both levels. If the pool drops faster than the bucket, that difference is the leak. In North Texas I also ask when the yard last moved, because clay soil pulls skimmers away from the shell in a dry August.
Answered by a Blue Science leak technician, DFW MetroplexWhy is my pool losing 1 inch of water a day?
Because an inch a day is more than evaporation. Evaporation in Carrollton runs up to about half an inch a day in the hottest, driest stretches and less most of the year, even with hard water, spring pollen, and July heat, so a pool that drops an inch every day is losing water somewhere: a skimmer throat, a return line, a light niche, a crack, or a fitting under the deck. The bucket test tells them apart in 24 hours, and it is the first thing our team at 972-893-1180 asks whether you have done. Our Carrollton leak detection visit starts at the equipment pad and works toward the shell, with hard water, spring pollen, and July heat in mind, and repairs are quoted separately once the source is found.
How can I find out where my pool is leaking from?
Start at the equipment pad, because a dripping pump seal, a weeping filter tank, or a loose union is a repair rather than a leak, and hard water, spring pollen, and July heat produce plenty of those. If the pad is dry, run the bucket test for 24 hours with the autofill off, then watch where the level stops: at the skimmer mouth points to the skimmer or a return line, below the light points to the niche or the main drain line, and a level that keeps falling points to the shell; in Carrollton our leak detection visit confirms it with pressure testing on the lines and dye at every fitting, as in all 41 cities we serve. In Carrollton the visit starts at the equipment pad and works toward the shell, with hard water, spring pollen, and July heat in mind.
What is the easiest way to find a leak in a pool?
Rule out evaporation first, with a bucket. Mark the pool level and a bucket filled to match, wait a day with the autofill off, and compare; in Carrollton, hard water, spring pollen, and July heat can push evaporation up, but the bucket shows exactly how much. Anything the pool loses beyond that is a leak, and the detection visit locates it with pressure on each line and dye at each fitting; 972-893-1180 books it. Turn the autofill off first in Carrollton, or the test measures nothing, whatever hard water, spring pollen, and July heat do.
What is the most common cause of pool leaks in Carrollton?
Fittings and plumbing under the deck, worked loose by hard water, spring pollen, and July heat. Skimmer throats separate, return lines crack where the deck settles, and light conduit corrodes in wet ground; in a Carrollton pool, under hard water, spring pollen, and July heat, 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 972-893-1180 is set up for. Once fixed, a Carrollton pool on weekly service gets its water level checked every visit, whatever hard water, spring pollen, and July heat bring.
Will my autofill hide a leak?
Completely, until the water bill arrives, and hard water, spring pollen, and July heat hide it further. An autofill replaces what the pool loses, so the level never moves and the only symptoms are a higher bill, chemistry that will not hold, and sometimes a damp patch in the Carrollton yard. Turn the autofill off before the bucket test and leave it off for the 24 hours, or the test measures nothing; 972-893-1180 can walk you through it.
