Pool Leak Detection for Preston Hollow
Water loss has a source; find it before it becomes a bigger problem
Preston Hollow sits on the white rock of the Austin Chalk, which drains a leaking pool line into itself without leaving a mark, and most of its lots have been rebuilt at least once, leaving 1950s pool runs under new driveways and additions beside spas and feature lines that can each lose water on their own. If the level keeps falling after the bucket test rules out evaporation, Blue Science finds the source and quotes the repair separately.
On a Preston Hollow pool we isolate the spa, the features, and each return loop and pressure test them one at a time, because a spillover that drains overnight looks exactly like a pool leak until the lines are separated, and on a rebuilt lot the original run gets tested before the new one.
Where a Preston Hollow pool loses water
A spa that drops to the spillover overnight, a feature pump that keeps catching air, a skimmer that gulps once the level drops an inch on the 1950s pools, a deck joint that opened along a new addition, or a water bill that climbed in August are the signs worth a call. White rock does not hold water, so a Preston Hollow leak almost never produces a soft spot in the lawn.
Spa check valves, feature lines, rerouted return lines under new construction, and skimmer throats and light niches on the original pools are the usual sources, and each is dye-tested during the visit.

Questions Preston Hollow 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 Preston Hollow 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. Call 972-953-6261 before the autofill hides it: in Preston Hollow 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?
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 water, spring pollen, and July heat or not. On a Preston Hollow 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 41 cities. In Preston Hollow 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 Preston Hollow, 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. In Preston Hollow the standard detection visit is quoted up front and the repair separately; 972-953-6261 has both numbers.
What is the most common cause of pool leaks in Preston Hollow?
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 Preston Hollow 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 972-953-6261 is set up for. Our Preston Hollow detection visit tests the skimmer and returns first because that is where the odds are, hard water, spring pollen, and July heat considered.
Is it a leak or evaporation in Texas weather?
Evaporation depends on the weather, meaning hard water, spring pollen, and July heat; a leak does not. In Preston Hollow 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 41 cities we serve.
