Evaporation or a leak? We find out

Pool Leak Detection in Los Angeles

We measure how fast your pool is really losing water, separate normal evaporation from a leak and trace the leak to its source. Equipment leaks we fix; anything deeper, we locate exactly.

  • Evaporation separated from real loss
  • Dye testing at fittings and cracks
  • Equipment pad leaks repaired
  • Clear findings you can act on

Pool leak detection in Los Angeles starts with an honest look at evaporation, because hot, dry, windy weather pulls a lot of water out of a perfectly healthy pool. The EPA estimates an uncovered 500-square-foot pool can lose 12,000 to 31,000 gallons a year to evaporation alone, depending on climate. (Source: U.S. EPA WaterSense)

Our job is to tell you whether your loss is more than that and, if it is, where the water is going. Leaks at the equipment pad and in above-ground plumbing we fix. If the leak is underground or in the pool shell, we show you exactly where it is and what it needs.

What's Included in Pool Leak Detection

  • Water loss measurement. Marked levels over set periods with the pump on and off, which helps narrow down which part of the system is leaking.
  • Bucket test. A side-by-side comparison of pool loss and bucket loss.
  • Equipment pad inspection. Pump, filter, heater, valves and every visible union checked for drips and air leaks.
  • Dye testing. Dye released at skimmers, returns, lights and cracks to see where water is pulled out.
  • Line checks. Plumbing lines isolated and pressure tested when the evidence points underground.
  • Written findings. What we found, what we fixed and what any remaining repair involves.

Signs Your Pool Has a Leak

The EPA's rule of thumb: a pool losing more than 2 inches of water a week, or 3 inches in hot, dry areas, likely has a leak. (Source: U.S. EPA WaterSense) Other clues:

  • An autofill that runs constantly, or a water bill that jumps
  • Faster loss with the pump running, or only with it off
  • Wet soil, soft spots or new green patches near the pool or equipment
  • Air bubbles at the returns or a pump that keeps losing prime
  • Salt or chemistry readings that keep dropping as fresh water dilutes them

Where Pool Leaks Usually Hide

  • Equipment pad. Pump shaft seals, lid O-rings, filter tank clamps, valves and unions. We repair these, often through our pool pump repair and pool filter repair services.
  • Skimmer. The joint where the skimmer body meets the pool wall shifts and cracks over time.
  • Fittings and lights. Return fittings, the light niche and the conduit behind it.
  • Shell and tile line. Structural cracks and failed grout at the waterline.
  • Underground plumbing. Suction and return lines running between the pool and the equipment.

Our Leak Detection Process

  1. Get the historyHow much water you add, and whether that changed after a repair or a quake.
  2. Run the bucket testA marked bucket of pool water sits on a step for 24 hours. If the pool drops more than the bucket, the pool may have a leak. (Source: U.S. EPA WaterSense)
  3. Compare pump on and offThe loss rate in each mode points us toward the suction side, the return side or the shell.
  4. Inspect the equipment padEvery seal, union and valve, where leaks are easiest to find and fix.
  5. Dye test the likely spotsSkimmers, returns, lights, steps and visible cracks, in still water.
  6. Isolate the linesIf the evidence points underground, lines are plugged and tested one at a time.
  7. Report and repairEquipment and above-ground plumbing leaks are fixed through our pool equipment repair work. Underground or shell leaks get an exact location and a plain description of the repair.

Leak Detection Methods Compared

MethodBest forTrade-offs
Bucket testAny pool that seems to lose waterNeeds a calm day; shows that there is a leak, not where
Pump on and off comparisonNarrowing a leak to part of the systemTakes a few days of readings
Equipment pad inspectionSeals, unions, valves and filter tanksOnly covers what is above ground
Dye testingSkimmers, fittings, lights and cracksNeeds clear, still water, so a green pool is cleaned first
Line pressure testingSuspected underground plumbing leaksIdentifies the line; pinning the spot along a buried pipe can take more work

If the answer is evaporation, a cover is the fix. The EPA says solid covers can cut evaporation by more than 90% when in use, yet only about 15% of pool owners have and regularly use one. (Source: U.S. EPA WaterSense)

What Affects the Cost of Pool Leak Detection

  • Pool size and whether there is an attached spa
  • How many plumbing lines run to the equipment
  • How many methods it takes to pinpoint the leak
  • Water clarity, since cloudy water must be cleared for dye work
  • Parts, if the leak is at the pump, filter or valves

Pool Leak Detection in Los Angeles: Local Factors

Normal loss depends on where you live. State water data puts yearly evaporative demand at about 50 inches in Los Angeles, 57 in Santa Clarita and 65 in Lancaster. (Source: California DWR) That spread is why the EPA's higher threshold for hot, dry areas fits the Antelope Valley better than the coast, while hillside lots and older plumbing add stress to skimmers and lines.

Why choose us

Why LA Homeowners Choose Us for Pool Leak Detection

1 company, find and fix

Found and Fixed by the Same Company

Many pool leaks turn out to be at the equipment pad: a worn pump seal, a cracked union, a filter tank clamp that weeps under pressure. Because we are licensed and insured for pool equipment repair, our owner, who finds that leak, can usually fix it too, instead of handing you a report and leaving you to find someone else.

6 readings every visit

Chemistry That Flags Hidden Loss

Every service visit ends with a photo and six readings texted to you: free chlorine, pH, alkalinity, calcium hardness, stabilizer and salt. For weekly customers, those numbers become an early warning system, because salt or stabilizer that keeps falling with no other cause usually means fresh water is replacing water that is leaking away somewhere. We point that out long before the water bill does.

Exact leak location

Plain Answers About What It Needs

When a leak is underground or in the shell, we do not guess or dig blind. We show you exactly where it is, what the repair involves, and whether it is urgent or can wait. If the answer is simply evaporation, we tell you that too, along with practical ways to cut it, such as a pool cover used regularly.

FAQ

Pool Leak Detection FAQ

How much water loss is normal for a pool in LA?

It depends on heat, wind, sun and whether the pool is covered. Inland valley pools lose more than coastal ones. The bucket test is the simplest way to separate normal evaporation from a leak.

Can you repair the leak once you find it?

Yes, when it is at the equipment pad or in above-ground plumbing, such as pump seals, valves, unions and filter tanks. For underground lines or the pool shell, we show you exactly where the leak is and what the repair needs.

Do I need to do anything before the leak test?

Turn off any autofill so it does not hide the loss, and tell us roughly how much water you have been adding. Keep swimmers out during the measurement period so splash-out does not skew the results.

Does a pool cover really reduce water loss?

Yes. The EPA says solid covers can cut evaporation dramatically when they are in use, yet few owners use one regularly. If your loss turns out to be evaporation, a cover is often the most effective fix.
