Our team relies on proven tests and repairs so your pool stays safe and ready for opening, regular maintenance, or even a renovation.
If you’re adding water more than once a week, that’s a red flag. Watch for wet or sinking ground near the deck, spongy concrete, or puddles that keep coming back.
Look for air bubbles at the return jets—those usually mean a suction-side plumbing leak. Cracks in plaster, loose tiles, or shifting coping? Those are signs of structural trouble and faster water loss.
If your water bill suddenly jumps, you might have an underground plumbing leak tied into the city supply.
We suggest a professional inspection if you spot any of these signs. Dolphin Pool Services will start with simple checks like the bucket test and a visual inspection, then move to advanced tests if needed.
We use electronic leak detection to trace signals along metal parts and plumbing lines. This method lets us find leaks under decks or inside walls without tearing up your yard.
Pressure testing of suction and return lines helps us isolate plumbing leaks. We pressurize pipe sections and watch for drops to spot hidden breaks.
For cracks in the structure or tile, we use dye testing near the suspect spots to confirm active leaks.
Sometimes we’ll do a camera inspection of underground pipes. The video shows us roots, breaks, or collapsed sections before we plan repairs.
These tools help us give you accurate quotes and avoid unnecessary work.
For plaster cracks and tile gaps, we use epoxy and hydraulic cement to seal leaks for good. We handle small surface repairs quickly, so you can get back to enjoying your pool in just a few days.
If we find plumbing leaks, we replace or reroute damaged pipes and fittings. We install new PVC lines, add proper bedding and tracer wire for future checks, and pressure-test everything after the repair.
When underground leaks threaten your deck or yard, we only dig where needed to keep disruption and costs low. At Dolphin Pool Services, we follow Maryland codes and use quality parts so your repairs last and your pool stays safe.
We focus on reliable, full-service pool care. Our team keeps your pool safe, efficient, and ready to use.

We get questions about water loss, what our techs actually do, typical costs, on-site service, plumbing vs shell leaks, and why it pays to hire a pro. Here are some quick answers for Rockville pool owners.
Try the bucket test. Fill a bucket with pool water, place it on a step, mark both the inside and outside water levels, run the pump 24 hours, and compare the drops.
If the pool level drops more than the bucket, you probably have a leak. Losing more than about a quarter-inch per day? That’s usually a leak, not just evaporation.
We start with a visual inspection of the pool shell, fittings, equipment, and visible plumbing. Then we run water level tests and dye testing near returns, lights, and skimmers.
Next, we use pressure testing and electronic listening gear to check underground or hidden plumbing. We wrap up with a written report and repair options, and can handle repairs if you want us to.
We give an upfront estimate after our initial inspection and testing. That way, you know what to expect before we get started.
Absolutely. We bring portable equipment right to your property. We perform dye tests, pressure tests, and electronic inspections at your pool.
On-site service means a faster diagnosis and less disruption—no need to remove decking or dig unless it’s truly necessary.
Yes, it can. Modern methods let us find leaks in underground lines, plumbing fittings, returns, skimmers, lights, and the pool shell.
We use non-invasive tools first, and only recommend excavation if tests show a buried line is the culprit.
Absolutely. Sure, you might spot some obvious leaks on your own, but hidden plumbing or underground problems? Those are easy to miss.
When you bring us in, we save you time and help cut down on wasted water. We also help you avoid expensive structural repairs later.
At Dolphin Pool Services, we use certified techniques and walk you through clear repair options. We want your inground pool to stay safe and beautiful for years to come.
