Pool leak detection in McKinney, TX from Blue Science: pressure and dye testing that finds where a McKinney swimming pool is losing water, even when hard water, spring pollen, and July heat make evaporation hard to judge, a written report with the location and the results explained, the leak repair quoted separately, and a 30-day warranty when we do the repair. Pricing varies by pool, so call for a quote on the standard leak detection visit.

Pool Leak Detection for McKinney
Find the source before water loss becomes a bigger problem
McKinney sits on blackland clay that swells through a wet spring and shrinks hard by August, and the decks and plumbing of pools built in Stonebridge Ranch thirty years ago and in Craig Ranch ten years ago are both riding that cycle, while the old plumbing behind the downtown houses has been riding it far longer. If your pool is losing more than evaporation explains, Blue Science finds the source and quotes the repair separately.
Clay leaks in McKinney show up in late summer when the ground pulls away from the shell, and which joint opened depends on the age of the pool: the rigid skimmer throat on a Stonebridge pool, a return fitting on a Craig Ranch pool, the light niche or main drain on a downtown pool. The pressure test says which before the dye goes in.
How a McKinney pool shows a leak
A level that drops faster with the pump running, a skimmer that gulps air once the level falls an inch, a deck slab that has tilted at a joint, a level that stops at the light on the older pools, or a strip of lawn that stays green through the August burn are the signs worth a call. Clay stresses the skimmer-to-shell joint first, then the return fittings, then the light conduit.
Skimmer throats, return fittings, light niches, and main drain lines on the downtown pools are the usual sources on McKinney pools, and each is dye-tested during the visit.

Good to know
Questions McKinney 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?
An inch a day usually means a leak, not the weather, even with hard water, spring pollen, and July heat. Evaporation takes a quarter inch or so on a hot McKinney day and far less in humid or cool weather; wind, a heater, a spa spillway, and hard water, spring pollen, and July heat push it up, but not to an inch. Run the bucket test, a bucket on the step filled to the pool level, 24 hours with the autofill off, and compare: water lost beyond what the bucket lost is leaking, most often at the skimmer, a return line, or a light niche, the pattern in all 41 cities we serve. Our McKinney 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 McKinney our leak detection visit confirms it with pressure testing on the lines and dye at every fitting, as in all 41 cities we serve. Detection and repair are quoted separately in McKinney, so you approve a defined fix; 972-953-6261 schedules both.
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 McKinney, 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; 972-953-6261 books it. The bucket test is also how our McKinney technicians check the repair afterward, against hard water, spring pollen, and July heat.
What is the most common cause of pool leaks in McKinney?
Movement. The deck and the shell move at different rates as hard water, spring pollen, and July heat work on a McKinney 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 41 cities we serve. Our McKinney detection visit tests the skimmer and returns first because that is where the odds are, hard water, spring pollen, and July heat 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 hard water, spring pollen, and July heat. A McKinney 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 41 cities.
