Leak Detection

At Diver Down, we perform a comprehensive underwater investigation. Our specialist enters your pool in full scuba gear to conduct a systematic, inch-by-inch scan of the entire interior. By being physically underwater for 45 minutes or more, we can identify precise points of water loss that electronic sensors might miss.

We use a meticulous manual scanning pattern to inspect every square inch of your liner, stairs, jets, returns, skimmers, main drains, and lights. If the leak is within the pool vessel, we repair it on the spot. If our testing indicates the leak is located deep within your plumbing, we provide a diagnostic report so your preferred pool company can handle the pipe repair.

Yes. Professional leak detection should always be done without draining the pool. In fact, we require the pool to be clean, clear, and filled to the normal operating level. The water pressure helps us identify the exact location of the leak through visual and dye testing.

Pressure testing is a specific diagnostic used to isolate and test the integrity of your underground plumbing lines. Scuba leak detection is a holistic approach where we inspect the entire pool structure liner, fixtures, and seals to find where the water is actually escaping.

We utilize specialized cone tests to isolate the plumbing lines from the pool shell. If our tests confirm a plumbing break, we can refer you to a partner company that utilizes sonic equipment to pinpoint the break within a two-foot radius, minimizing the need for extensive excavation or jackhammering of your deck.

While many use electronic sensors, we believe nothing is as accurate as the human eye. Our specialists use magnifiers within their scuba masks to scan the pool from top to bottom. This "hands-on" approach allows us to find and feel micro-tears that technology often overlooks.

Absolutely. Our standard service fee includes both the comprehensive inspection and the on-the-spot repair of any leaks found within the pool structure. We carry all necessary materials to patch liners or seal fixtures immediately, with no extra charge for the repair.

In the vast majority of cases, no. If the leak is located in the liner or any pool fixtures (lights, jets, or drains), the repair is done entirely from inside the pool. Digging is only necessary if a major pipe break is confirmed under the ground.

The most common culprit is a tear or pinhole in the vinyl liner. However, we frequently find leaks in high-stress areas like skimmer throats, pool stairs, return jets, underwater lights, and main drains.

Yes. Repairing vinyl liner tears is the core of our business. We use professional-grade underwater vinyl adhesives and vinyl patches that create a permanent seal without the need to drain your pool.

Most appointments take approximately one hour. This allows us enough time to perform a full scuba circuit of the pool, conduct plumbing isolation tests if necessary and complete any needed repairs.

If a leak is determined to be in the plumbing underneath your concrete or pavers, we can most likely identify it and refer you to a partner company who can find the break within a 2 foot radius, and do the excavating and repairs.
