Pool Leak Detection for Lago Vista
Find the source of the water loss before it becomes a bigger Lago Vista problem
A leaking pool in Lago Vista drains into fractured limestone and downhill toward Lake Travis, so the yard stays dry and the only witness is the water level. If the pool needs topping off every visit to the lake house, Blue Science finds the source and quotes the repair separately.
Weekend owners rarely see the level drop day to day, so we ask for a photo of the tile line at arrival and departure, which tells us more than a guess, and then we pressure test each line on the hillside run before dye-testing the shell.
Leak clues at a Lago Vista lake house
A level that is lower every Friday than it was on Sunday, a pump below the pool that keeps catching air, a return that spits, or a deck slab that has tipped on the downhill side are the clues worth a call. Wind across the lake evaporates real water, so the bucket test runs first.
Return fittings on long downhill runs, skimmer throats, and light conduits are the usual sources on Lago Vista pools, and each is dye-tested during the visit.

Questions Lago Vista 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, Greater AustinWhy is my pool losing 1 inch of water a day?
An inch a day usually means a leak, not the weather, even with hard Hill Country water, cedar pollen, and 100-degree summers. Evaporation takes a quarter inch or so on a hot Lago Vista day and far less in humid or cool weather; wind, a heater, a spa spillway, and hard Hill Country water, cedar pollen, and 100-degree summers 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 14 cities we serve. Call 512-777-4460 before the autofill hides it: in Lago Vista 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?
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 hard Hill Country water, cedar pollen, and 100-degree summers are doing. What you cannot see from the deck, a Lago Vista leak detection visit finds by pressure-testing each line and dye-testing the fittings and the shell, the same routine across 14 cities. In Lago Vista the visit starts at the equipment pad and works toward the shell, with hard Hill Country water, cedar pollen, and 100-degree summers 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, hard Hill Country water, cedar pollen, and 100-degree summers 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 Lago Vista that takes a day and no tools, and finding the source takes the pressure and dye testing of a detection visit, one call to 512-777-4460. The bucket test is also how our Lago Vista technicians check the repair afterward, against hard Hill Country water, cedar pollen, and 100-degree summers.
What is the most common cause of pool leaks in Lago Vista?
Movement. The deck and the shell move at different rates as hard Hill Country water, cedar pollen, and 100-degree summers work on a Lago Vista 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 14 cities we serve. Once fixed, a Lago Vista pool on weekly service gets its water level checked every visit, whatever hard Hill Country water, cedar pollen, and 100-degree summers bring.
Is it a leak or evaporation in Texas weather?
Evaporation depends on the weather, meaning hard Hill Country water, cedar pollen, and 100-degree summers; a leak does not. In Lago Vista the same conditions can push evaporation to about half an inch a day at the worst, and it slows in humid or cool weather, while a leak loses the same amount every day. If the loss is steady through a rainy week or a cool one, it is a leak, and the bucket test settles it in a day, the first step in every one of the 14 cities we serve.
