We follow the evidence, pressure testing, dye testing, and focused inspection, then explain what we found on your Katy pool and the practical next step.
Pool Leak Detection for Katy
Find the source of the water loss before it becomes a bigger Katy problem
Katy sits on gumbo clay over a shallow water table, so the ground swells every wet season, shrinks every dry one, and swallows any leak without leaving a damp spot. If your pool is losing more than evaporation explains, Blue Science finds the source and quotes the repair separately.
A fifteen-year-old Katy pool can leak as easily as an old one, because clay movement stresses return fittings and skimmer throats early. We test rather than guess, and we show you what we found before proposing a repair.
Leak clues in a Katy pool
An autofill that never rests, air in the pump basket, a level that drops faster with the pump running, a deck slab that has dropped on the clay, 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.
Clay movement opens skimmer-to-shell joints and return fittings in Cinco Ranch and Grand Lakes, and each is dye-tested during the visit.
Leak detection for Katy, Cinco Ranch, and Fulshear
Our leak technicians cover Katy, Cinco Ranch, and Fulshear on the same schedule as our weekly routes, so a visit can be arranged quickly. Call for pricing on the standard leak detection visit, and repairs are quoted separately once the source is found.
Detection carries a 30-day warranty when Blue Science performs the repair, and the line is retested afterward.

Good to know
Questions Katy 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 HoustonWhy is my pool losing 1 inch of water a day?
Because something is leaking. A Katy pool loses water to evaporation, splash-out, and backwashing, but even Gulf humidity, pollen, and afternoon storms 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 27 cities. Our Katy leak detection visit starts at the equipment pad and works toward the shell, with Gulf humidity, pollen, and afternoon storms in mind, and repairs are quoted separately once the source is found.
How can I find out where my pool is leaking from?
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 Gulf humidity, pollen, and afternoon storms 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 Katy our leak detection visit confirms it with pressure testing on the lines and dye at every fitting, as in all 27 cities we serve. Our Katy technicians document the source with photos before any repair is proposed, whatever Gulf humidity, pollen, and afternoon storms did to the pipes.
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 Katy, Gulf humidity, pollen, and afternoon storms 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; 281-882-3937 books it. Turn the autofill off first in Katy, or the test measures nothing, whatever Gulf humidity, pollen, and afternoon storms do.
What is the most common cause of pool leaks in Katy?
Fittings and plumbing under the deck, worked loose by Gulf humidity, pollen, and afternoon storms. Skimmer throats separate, return lines crack where the deck settles, and light conduit corrodes in wet ground; in a Katy pool, under Gulf humidity, pollen, and afternoon storms, 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 281-882-3937 is set up for. The repair is quoted separately in Katy, and the 30-day warranty covers detection when we do the work; 281-882-3937 explains both.
Is it a leak or evaporation in Texas weather?
Evaporation depends on the weather, meaning Gulf humidity, pollen, and afternoon storms; a leak does not. In Katy 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 27 cities we serve.
