Customer Success Story · Pool & Spa Leak Detection

Lucia M. in Downtown Bakersfield, Bakersfield noticed air bubbles coming from returns or unusual noise from the pump and wasn't sure how serious it was. We use a bucket test to separate evaporation from true leaks, dye testing to check skimmers and fittings, and pressure testing on plumbing lines. For suspected shell leaks, a dive inspection can visually confirm the leak point. What could have meant a much bigger job instead only needed one targeted repair.

What is pool & spa leak detection?

With California's climate, pools and spas run for most of the year, which means even a small leak adds up fast in lost water and can eventually undermine the surrounding decking or yard. We test pool shells, skimmers, return lines, main drains, and equipment pad plumbing to determine whether water loss is from evaporation or an actual leak, and if it's a leak, exactly where.

We use a bucket test to separate evaporation from true leaks, dye testing to check skimmers and fittings, and pressure testing on plumbing lines. For suspected shell leaks, a dive inspection can visually confirm the leak point.

Signs you may need pool & spa leak detection

  • Water level dropping noticeably faster than normal evaporation would explain
  • Wet spots, soft ground, or sinking pavers near the pool equipment pad or shell
  • Air bubbles coming from returns or unusual noise from the pump
  • A consistent need to add water beyond typical seasonal loss
  • Cracks appearing in pool decking or tile line
  • Rising water bills during pool season

How pool & spa leak detection works

  1. Schedule your inspection

    Call or request an appointment online. Same-day slots are available across California for active leaks.

  2. On-site diagnostic

    A technician arrives with acoustic listening equipment, thermal imaging, and pressure or camera tools matched to your specific leak type.

  3. Pinpoint & confirm

    The leak's exact location is marked and explained to you in plain terms, so nothing gets opened up on a guess.

  4. Clear next steps

    You receive a written diagnostic report you can hand to your plumber, restoration team, or insurance company, with repair or fix options discussed on the spot.

What California homeowners say about pool & spa leak detection

★★★★★

“The floor in our hallway had a warm spot for weeks. They found the slab leak in under an hour with the listening equipment and marked a tiny area instead of tearing up the whole hallway. Huge relief.”

MTMarcus T. · Los Angeles, CA
★★★★★

“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”

PRPriya R. · Los Angeles, CA
★★★★★

“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”

DKDaniel K. · San Diego, CA
★★★★☆

“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”

AMAngela M. · San Diego, CA
★★★★★

“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”

CBChris B. · San Francisco, CA
★★★★★

“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”

WLWei L. · San Francisco, CA

Pool & Spa Leak Detection FAQs

How much water loss is normal for a pool versus a sign of a leak?Toggle answer
Evaporation typically accounts for roughly a quarter to half an inch of water loss per day depending on heat, wind, and sun exposure. Loss beyond that range, especially if it continues with the pump off, usually points to an actual leak rather than evaporation.
Can you find a leak in the pool's plumbing lines without digging up the yard?Toggle answer
Pressure testing lets us isolate which line is losing pressure without excavation. Once the affected line and general area are identified, only that section needs to be accessed for repair.
Do you inspect spa and equipment pad leaks too, or only the pool itself?Toggle answer
Both. Attached spas, jets, heaters, filters, and pump seals at the equipment pad are all common leak points and are part of a complete pool and spa leak inspection.
