You can count on our experienced local team to handle even the trickiest leaks in plumbing, equipment, or right in the pool shell.

We rely on trusted tools and our local knowledge to give you clear estimates and real solutions. Choosing Dolphin Pool Services saves you time, protects your yard, and helps prevent bigger problems with your pool or equipment down the line.

We find and fix leaks quickly using trained technicians, modern tools, and straightforward pricing. Our team handles leaks in pool shells, plumbing, equipment, and liners, all while protecting your landscaping and pool finish.
Watch for steady water loss that goes beyond normal evaporation. If your pool drops more than an inch per day or you’re refilling it way too often, something’s probably wrong.
Check for wet or soggy spots around the deck, low areas in your yard, or even sinkholes near the pool. If you see air bubbles in the pump strainer, lose prime, or notice your chemicals are always out of balance, you might have a leak in the plumbing or equipment.
Cracks in the tile, plaster, or visible liner separation can also mean structural leaks.
Try tracking water loss with a bucket test, but if you’re unsure, call us. We’ll make sure you avoid misdiagnosis and further damage.
We use non-invasive tools to pinpoint leaks—no need to tear up your yard or deck. Our team uses pressure testing for underground plumbing and electronic acoustic listening to find hidden water flow.
Dye tests help us spot cracks, skimmer and return fitting leaks, and liner separations. We also use ultrasonic and infrared devices to find leaks under concrete and decking. For liners, we check seams visually and sometimes use vacuum-box testing.
We often combine these methods to confirm what’s going on before we start repairs. This keeps repair costs down and helps pool openings and renovations stay on schedule.
Our repair plans depend on where the leak is and what type of pool you have. For underground lines, we use sectional excavation and pipe replacement or slip-lining to restore flow.
We replace seals, valves, or corroded fittings for equipment leaks.
For cracks in plaster or tile, we use epoxy or patching compounds that hold up in Virginia’s climate. If your liner tears, we’ll weld or replace it depending on its age and condition.
When we handle decks or pool renovations, we coordinate repairs to protect your landscaping and make sure everything meets local codes.
We use quality parts and offer warranties when possible. When you choose Dolphin Pool Services, you get durable repairs and peace of mind knowing your pool is in good hands.
Look for a team with real local experience in Gainesville, Northern Virginia, and nearby areas. Make sure they’re licensed, insured, and have solid references for leak detection and repairs.
Ask about the tools we use, warranty terms, and whether we handle plumbing, maintenance, and renovations. Request a written estimate that lists the tests performed, repair steps, parts, and timeline.
We recommend choosing a provider who documents findings with photos and pressure test data. That way, you know the job was done right.

We’ll help you spot real leaks, understand why rapid water loss happens, what detection involves, and the tools we use. We also cover if DIY checks help and how to choose a reputable company like Dolphin Pool Services.
Evaporation usually causes a small, steady loss—less than a quarter-inch per day in most weather. If you see water dropping faster, wet spots around the pool, or soggy ground, that’s a red flag.
Try the bucket test: fill a bucket, set it on a pool step, and mark water lines inside the bucket and on the pool. After 24 hours, compare levels; if the pool drops more than the bucket by about 1/4″ or more, you probably have a leak. If you’re not sure, give us a call.
Losing 2 inches a day is way more than normal evaporation. That usually means broken underground plumbing, a crack in the shell, a faulty skimmer or return fitting, or leaking equipment.
This much loss can wreck your decking and pool structure fast. Stop adding chemicals and call our leak detection team as soon as possible.
Leak detection often starts around a few hundred dollars and can go higher for complex cases. The price depends on where the leak is, how deep the plumbing runs, the time needed for pressure testing, and whether repairs are needed after detection.
If we need excavation, sonar, or advanced electronic tracing, the cost goes up. We always provide clear estimates after inspecting and testing.
DIY checks can help narrow things down and save some time, but they rarely find hidden plumbing leaks. We use calibrated equipment and years of experience to pinpoint leaks quickly and help you avoid unnecessary repairs.
Try the basics (bucket test, check visible fittings), but if you suspect a leak, call us. We usually find the exact source fast, which can save you money in the long run.
We use several non-invasive methods: pressure testing plumbing lines, dye testing around fittings and cracks, electronic listening devices to hear water under concrete, and ultrasonic or infrared tools for tough spots.
We also visually inspect equipment, skimmers, and tile lines.
We combine these tools as needed to pinpoint leaks with minimal disruption to your yard and pool finish.
Start by checking if the company has real credentials and a solid history working locally. It helps to see if they offer clear, straightforward estimates.
When you read reviews, pay attention to details about how they diagnose leaks and whether they show up on time. People often mention if the repairs are clean and if the service feels fair.
