Pool Leak Detection in San Antonio, TX

Three things drop a pool an inch a day, and only one of them is normal. Evaporation on the hottest San Antonio days can take up to half an inch, hard water, cedar and oak pollen, and 90-degree water permitting; splash-out and backwashing take a little more on a busy weekend; everything past that is a leak. Pressure-side leaks show up as a wet spot or a pump that spits air, suction-side leaks as air in the pump basket, and shell leaks as a level that stops dropping at the same spot every time, which our leak detection visit sorts out with pressure tests and dye in any of the 7 cities we cover. Detection is warranted for 30 days in San Antonio when Blue Science makes the recommended repair, in all 7 cities we serve.

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, cedar and oak pollen, and 90-degree water 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 San Antonio our leak detection visit confirms it with pressure testing on the lines and dye at every fitting, as in all 7 cities we serve. In San Antonio the visit starts at the equipment pad and works toward the shell, with hard water, cedar and oak pollen, and 90-degree water in mind.

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 San Antonio, hard water, cedar and oak pollen, and 90-degree water 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; 210-704-1400 books it. The bucket test is also how our San Antonio technicians check the repair afterward, against hard water, cedar and oak pollen, and 90-degree water.

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 Antonio, hard water, cedar and oak pollen, and 90-degree water 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 7 cities. Our San Antonio detection visit tests the skimmer and returns first because that is where the odds are, hard water, cedar and oak pollen, and 90-degree water considered.

Yes, in three ways, and hard water, cedar and oak pollen, and 90-degree water 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 Antonio the leak that started in spring is a bigger job by fall, which is why 210-704-1400 is worth a call early.
