We find a pool or spa leak without draining it by pressure-testing the plumbing lines, running a dye test at suspected spots, and using acoustic listening equipment for underground pipe leaks, then confirming the exact source before any repair is recommended.
Here’s the order we work in: test the system to isolate whether the leak is in the plumbing or the pool itself, confirm the exact spot, then talk about repair, never the other way around. That sequence is why we don’t need to drain your pool or dig up your yard just to go looking.
None of these signs confirms a leak on its own, evaporation, splash-out, and normal water use all account for some water loss too, but any one of them is worth a check, and more than one together is a stronger signal:
If you’re not sure whether what you’re seeing is a real leak or just normal water loss, our DIY checks guide walks through two simple tests you can try before you call anyone.
Each method answers a different question, so we don’t rely on just one.
For a leak we suspect is in the shell or liner itself rather than the plumbing, a visual or dive inspection of the pool’s surface completes the picture. We use these together because a pool leak that looks like one thing (a wet equipment pad) can turn out to be another (a cracked return line ten feet away), and guessing at that difference before testing is how a repair ends up in the wrong spot.
Leak detection for swimming pools splits into these same two problems, the shell and fittings versus the plumbing, and pool leak detection services vary in whether they actually check both. A proper swimming pool leak detection visit addresses both before calling it done, and swimming pool plumbing repair on the specific line or fitting we identify follows only once that split is clear. If you’re comparing one pool leak detection company to another, ask whether their quoted price includes pressure-testing the lines or only a visual check, because a swimming pool leaking detection visit that skips the plumbing hasn’t finished the job.
Most pool leaks are in the plumbing lines that circulate water to and from the pool, which is usually a more straightforward repair, but a smaller number are in the pool’s shell or liner itself, which is a different kind of job and worth knowing about before you get a quote.
We won’t tell you which category your leak falls into before we’ve actually tested for it; that’s the point of the methods above. What we can tell you now is that this distinction is exactly why a firm price only comes after detection, not before it.
Once we know whether the leak is in the plumbing or the pool’s shell, repair moves straight ahead on the same visit wherever it’s accessible, priced only after the source is confirmed. From here, this page covers what that repair actually involves, what it costs, how to check things yourself before you call, and why a specialist matters for something in your own backyard.
Pool leak repair follows detection on the same visit wherever the fix is accessible. Finding the leak is the hard part; once the location is known, most repairs are contained work rather than a rebuild.
Swimming pool leak repair is not a single price because it is not a single job. What we can promise before we arrive is the detection fee, and that the repair quote comes in writing after the leak is located, never before.
Pool leak detection is priced the same as our other non-invasive detection calls, generally $150 to $500, and that fee is credited toward the repair if you move forward; the repair itself varies too widely to quote here without seeing your pool, which is why we always confirm it with a firm written quote. See our full pool leak detection and repair cost breakdown → for what actually drives that repair-cost range.
If you want a first read on whether you actually have a leak before scheduling a visit, a bucket test and a dye test can point you in the right direction, though neither replaces a professional inspection. The pool bucket test works by comparing loss rates: set a bucket of pool water on a step, and if the pool drops faster than the bucket over the same period, you’re losing water to something beyond normal evaporation. See our full DIY checks before you call a pool leak professional → for step-by-step instructions and, just as usefully, when to stop checking it yourself and call us instead.
One caution applies no matter which test you run: never drain the pool yourself to look for the leak. Draining an in-ground pool incorrectly can cause real structural damage, since an empty or partially empty pool can shift, crack, or even pop up out of the ground under certain soil and water-table conditions, and there’s no way to know in advance whether your specific pool and yard are at risk.
The number that makes the bucket test mean something: a pool losing about a quarter-inch a day is evaporating normally, and in hot, dry weather that can reach half an inch. What matters is not the absolute drop but the difference — if the pool falls further than the bucket over the same period, the gap is the leak.
Run it twice, once with the pump running and once with it off. A loss that gets worse with the pump on points at the pressure side of the plumbing; a loss that is the same either way points at the shell or the suction side. That one extra step narrows the search before anyone arrives. Repair options are on pool leak repair, and if it is a spa rather than the pool, spa losing water covers where they differ.
Finding a pool leak precisely takes the same kind of equipment-specific repetition that finding a slab leak does: running pressure tests, dye tests, and acoustic equipment on leak after leak until reading the results correctly is routine, not a guess. A general plumber or a pool-service company that occasionally handles a leak call is more likely to fall back on trial and error, because renting or maintaining detection equipment for one job rarely makes sense for someone who mostly does other work.
We find the leak and repair it, the same team, start to finish, so nothing about where the leak actually is gets lost in a hand-off between a “detection company” and a separate repair crew.
Usually not an immediate emergency. It is still worth scheduling a detection visit soon rather than waiting it out. A slow leak that goes unaddressed can waste a meaningful amount of water and, over time, affect the ground and decking around the pool. If you’re seeing rapid, obvious water loss, a sudden pressure change in a return line, or standing water where it shouldn’t be, that’s worth a same-week call rather than something to watch for a while first.
A pool leak on its own isn’t the kind of situation our 24/7 emergency line is built for, but if it’s paired with flooding elsewhere on the property, a burst pipe or active slab leak, that line is available any time.
We serve residential pools and spas throughout Santa Ana, including the city’s older neighborhoods where in-ground plumbing and pool equipment tend to be older too. See our full service area → if you’re checking whether we cover your part of Orange County.
We test the plumbing lines and the pool itself to find the exact source, with no draining required.
(714) 386-7923Call or text, day or night Book a Detection VisitWe isolate whether the leak is in the plumbing lines or the pool’s shell or liner using pressure testing, dye testing, and acoustic/electronic listening equipment, then confirm the exact spot before recommending a repair. No draining required to find it.
A bucket test and a dye test can give you a preliminary read on whether you have a real leak and roughly where it might be, but both are preliminary checks, not a substitute for a professional inspection. See our full DIY checks guide → for the step-by-step method.
As a general rule of thumb, a healthy pool typically loses somewhere around a quarter-inch of water a day to evaporation alone, more in hot, dry, or windy weather. This is a widely used industry guideline, not a precise measurement for your specific pool, so treat it as a starting point for comparison, not a verified figure.
Pool leak detection is priced at $150 to $500, credited toward the repair if you move forward. Repair cost depends on what we find and isn’t something we can quote without seeing your pool. See our full cost breakdown →.
A slow, ongoing leak can affect the soil and decking around the pool over time, though it’s rarely an overnight problem. It’s a reason to have a suspected leak checked sooner rather than later, not a cause for alarm about your home’s foundation.
No, not usually. Pressure testing, dye testing, and acoustic listening all work with the pool full, which is the whole point of a non-invasive approach: finding the leak doesn’t require draining the pool first.
Usually not an immediate emergency. It is not something to leave unaddressed either. Rapid, obvious water loss or standing water where it shouldn’t be is worth a same-week call.
No. We locate and repair pool and spa leaks; pool remodeling, resurfacing, and new construction are outside what we do. If your pool needs that kind of work, a pool leak inspection can still tell you whether a leak is part of what’s driving the decision.
