Is Your Pool Leaking?

6 Warning Signs of a Pool Leak

Not sure if your pool is leaking? Look for these common indicators. If you notice one or more of these signs, it's time to investigate further.

Unexplained Water Loss

Your pool loses more than 1/4 inch of water per day beyond normal evaporation, requiring frequent refills.

Cracks in Pool Shell

Visible cracks in the plaster, gunite, or fiberglass shell that could indicate structural movement or settling.

Air in the Pump System

Air bubbles in the pump basket or return jets suggest a suction-side leak in the plumbing lines.

Wet Spots in the Yard

Unexplained soggy or soft areas around the pool deck or yard, especially near plumbing lines.

Chemical Imbalance

Constantly needing to add chemicals despite regular treatment may indicate water is leaking and being replaced with untreated water.

Loose or Shifting Tiles

Pool tiles or coping stones that are coming loose, cracking, or shifting can indicate water erosion behind the surface.

Our Detection Process

How We Find Pool Leaks

Our systematic 3-step approach starts with the simplest test and escalates to advanced technology only when needed — saving you time and money.

The Bucket Test - Your First Step — DIY Evaporation Test
Your First Step — DIY Evaporation Test

Step 1: The Bucket Test

Before scheduling a professional leak detection service, we always recommend starting with the bucket test. This simple DIY method helps determine whether your pool is actually leaking or just losing water to normal evaporation — especially important in Miami's hot, humid climate.

1
Fill a 5-gallon bucket with pool water and place it on the second step of your pool
2
Mark the water level inside the bucket with tape or a marker
3
Mark the pool water level on the outside of the bucket
4
Turn off the pump and any auto-fill devices
5
Wait 24 hours without using the pool
6
Compare the two water levels — if the pool level dropped more than the bucket level, you likely have a leak

Pro Tip

Run the test twice: once with the pump off and once with it running. If you lose more water with the pump on, the leak is likely in the plumbing. If water loss is the same, the leak is probably in the pool shell.

Dye Testing - Pinpointing the Exact Leak Location
Pinpointing the Exact Leak Location

Step 2: Dye Testing

Once the bucket test confirms a leak, our technicians use professional-grade leak detection dyes to pinpoint the exact location. This non-invasive method is highly effective for finding leaks around fittings, returns, skimmers, lights, and cracks in the pool shell.

1
Turn off all pool equipment to eliminate water movement
2
Identify suspected leak areas (fittings, lights, cracks, tile line)
3
Release a small amount of concentrated dye near the suspected area
4
Watch the dye carefully — if it gets pulled toward a crack or gap, that's your leak
5
Mark each confirmed leak location for repair
6
Test all fittings, returns, and skimmer areas systematically

Pro Tip

Dye testing works best in calm water. We test on still days and turn off all equipment at least 30 minutes before testing to ensure accurate results.

Electronic Leak Detection - Professional Equipment for Underground Leaks

Step 3: Electronic Leak Detection

For leaks that can't be found visually — especially underground pipe leaks — we deploy specialized electronic listening equipment and pressure testing systems. These professional tools can detect leaks buried under concrete decks, in plumbing lines, and within the pool structure itself.

1
Pressure test all plumbing lines (suction and return) to isolate which line is leaking
2
Use acoustic listening devices to detect the sound of water escaping underground pipes
3
Deploy electronic sensors along the pipe path to pinpoint the exact leak location
4
Use specialized hydrophones for underwater leak detection in the pool shell
5
Map the leak location precisely to minimize excavation and repair costs
6
Provide a detailed report with findings and recommended repair options

Pro Tip

Electronic detection can find leaks as small as a pinhole in underground pipes without any digging. This saves you thousands in unnecessary excavation costs.

Where Leaks Hide

Common Pool Leak Locations

Pool leaks can occur in many places. Here are the most common areas we inspect during a comprehensive leak detection service.

Skimmer

The joint between the skimmer and pool wall is one of the most common leak points, especially in older pools where the sealant has deteriorated.

Return Fittings

Wall return fittings and their gaskets can crack or loosen over time, allowing water to seep behind the pool shell.

Pool Light Niche

The conduit and housing around pool lights are frequent leak sources, especially if the light fixture has been replaced or serviced.

Main Drain

The main drain at the pool bottom and its plumbing connection can develop leaks from ground settling or age-related deterioration.

Underground Plumbing

Suction and return pipes buried under the deck can crack from ground movement, tree roots, or corrosion over time.

Pool Shell Cracks

Structural cracks in the plaster, gunite, or fiberglass shell allow water to escape into the surrounding soil.
