Pool Leak Detection in San Marcos, TX

Because something is leaking. A San Marcos pool loses water to evaporation, splash-out, and backwashing, but even hard Hill Country water, cedar pollen, and 100-degree summers cannot evaporate an inch every day. The fastest check is the bucket test: match a bucket on the step to the pool level, turn the autofill off, and compare after a day; the bucket shows the evaporation, the gap is the leak, and its size tells us whether to look first at a fitting, a line, or the shell, as it does across all 14 cities. Our San Marcos leak detection visit starts at the equipment pad and works toward the shell, with hard Hill Country water, cedar pollen, and 100-degree summers in mind, and repairs are quoted separately once the source is found.

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, hard Hill Country water, cedar pollen, and 100-degree summers or not. On a San Marcos 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 14 cities. Detection and repair are quoted separately in San Marcos, so you approve a defined fix; 512-777-4460 schedules both.

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 hard Hill Country water, cedar pollen, and 100-degree summers are doing. If a San Marcos 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 14 cities we serve. The bucket test is also how our San Marcos technicians check the repair afterward, against hard Hill Country water, cedar pollen, and 100-degree summers.

The skimmer, first and by a wide margin. The throat where the skimmer meets the shell moves every time the deck and the pool move differently, and in San Marcos, hard Hill Country water, cedar pollen, and 100-degree summers keep them moving. Return fittings and light niches come next, then underground lines where a deck has settled, and shell cracks last; each shows a different pattern in the water level, and the dye test confirms it in minutes, as it has across 14 cities. Once fixed, a San Marcos pool on weekly service gets its water level checked every visit, whatever hard Hill Country water, cedar pollen, and 100-degree summers bring.

Yes, in three ways, and hard Hill Country water, cedar pollen, and 100-degree summers speed all three. Every day the autofill covers the loss you pay for water and for the chemicals that leave with it; water leaving under the deck washes out the fill and settles the deck, which opens more joints; and a pool that drops below the skimmer lets the pump suck air and run dry, which turns a leak call into a repair call. In San Marcos the leak that started in spring is a bigger job by fall, which is why 512-777-4460 is worth a call early.
