Pool Leak Detection for Lewisville
Find the source before water loss becomes a bigger problem
Lewisville has two kinds of leaking pools: decades-old plumbing under the pecans of Old Town and Garden Ridge, and newer shells in Castle Hills still settling on blackland clay. If your pool is losing more than evaporation explains, Blue Science finds the source and quotes the repair separately.
On an old Lewisville pool we look at the skimmer throat and the light niche first; on a new one we look at the return fittings the clay has been working on. Either way we test rather than guess, and we show you what we found before proposing a repair.
Leak clues in a Lewisville pool
Air in the pump basket, a level that drops faster with the pump running, a deck slab that has lifted or dropped at a joint, a soft spot in the yard, or a jump in the water bill are the signs worth a call. The bucket test below separates summer evaporation from a real leak in a day.
Root-bound original PVC in Garden Ridge and clay-stressed fittings in Castle Hills are the usual sources, and each is dye-tested during the visit.

Questions Lewisville 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 Lewisville 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 Lewisville 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?
Work from the easy checks to the hard ones, with hard water, spring pollen, and July heat in mind. Look at the pad first for a wet pump seal or a weeping filter; then run the bucket test for a day with the autofill off; then let the water level tell you where it stops, since a stop at the skimmer, at the light, or at the returns each points to a different suspect, and in Lewisville the plumbing joints are the usual answer, which the pressure test names, a call to 972-953-6261 away. In Lewisville 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?
The bucket test, and it costs nothing, hard water, spring pollen, and July heat or not. Set a bucket on the top step, fill it to match the pool, mark both lines, and leave the pool running normally for a day with the autofill off; if the pool drops more than the bucket, the difference is a leak. That tells you there is one; finding it in a Lewisville pool usually takes pressure testing the suction and return lines and dye testing the fittings, lights, and skimmer, which is what the detection visit does in all 41 cities. Turn the autofill off first in Lewisville, or the test measures nothing, whatever hard water, spring pollen, and July heat do.
What is the most common cause of pool leaks in Lewisville?
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 Lewisville, hard water, spring pollen, and July heat 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 41 cities. Our Lewisville detection visit tests the skimmer and returns first because that is where the odds are, hard water, spring pollen, and July heat considered.
Does a leaking pool get worse if I wait?
Yes, in three ways, and hard water, spring pollen, and July heat 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 Lewisville the leak that started in spring is a bigger job by fall, which is why 972-953-6261 is worth a call early.
