Signs You Have an Underground Pool Leak

Doc’s Leak Detection • Indianapolis & Central Indiana

Underground pool leaks can be frustrating because the problem is not always visible from the surface. The pool may look fine while water is escaping below the deck or through buried plumbing.

Common warning signs

• Wet or soft areas around the pool deck, equipment pad, or yard.
• Air bubbles returning to the pool or air collecting in the pump basket.
• Water loss that continues even after basic evaporation checks.
• Cracks, settling, washed-out areas, or movement around the pool deck.

Why guessing can get expensive

• Digging in the wrong place can create more damage than the leak itself.
• A non-invasive-first diagnostic approach helps narrow down likely leak sources before repairs are planned.
• Pressure testing can help determine whether a plumbing line is holding pressure or losing water.

How we approach it

• We start with visible inspection and site conditions.
• We isolate possible sources such as suction lines, return lines, fittings, lights, and equipment-side plumbing.
• We document findings so the homeowner, pool company, or repair contractor has clearer direction.
