Pool Leak Detection
Find and fix hidden leaks before they cause major damage
Is Your Pool Losing Water?
Quick Answer
Pool leaks waste thousands of gallons and can undermine your pool structure. Start with a simple bucket test to confirm water loss isn't just evaporation. Most leaks occur at equipment (pump seals, filter tanks) or pool fittings (returns, lights, skimmers). Underground pipe leaks require professional detection equipment using acoustic, pressure, or camera methods. Quick action prevents expensive structural damage and high water bills.
Leak Detection Safety
- •Large leaks can undermine pool deck and cause sinkholes
- •Electrical hazards exist near pool lights and equipment
- •Never dig without calling 811 for utility marking
- •Structural cracks may indicate serious foundation issues
Common Pool Leak Locations
Equipment Leaks (60%)
- ✓Pump shaft seal: Most common equipment leak
- ✓Filter tank: Cracks or bad o-ring
- ✓Valve seals: Multiport or ball valves
- ✓Heater: Heat exchanger or headers
Structural Leaks (40%)
- ⚠️Skimmer: Cracks or separation from pool
- ⚠️Return fittings: Loose or cracked
- ⚠️Light niches: Conduit or seal failure
- ⚠️Main drain: Rare but serious
Step-by-Step Leak Detection
Step-by-Step Diagnosis
Perform Bucket Test
Place a bucket on pool step, fill to match pool water level. Mark both levels. Compare after 24 hours.
⚠️ Warning: If pool loses more water than bucket, you have a leak
Check Obvious Leak Points
Inspect equipment pad for wet spots, check pump seals, filter tank, valves, and visible plumbing
Test with Pump On vs Off
Measure water loss for 24 hours with pump running, then 24 hours with pump off. Compare rates.
⚠️ Warning: Higher loss with pump on = pressure side leak. Higher loss with pump off = suction side or structural leak
Dye Test Suspected Areas
Use leak detection dye near returns, lights, skimmers, and cracks. Watch if dye gets pulled into leak.
Inspect Pool Structure
Check for cracks in plaster, tile line separation, or gaps around fittings and lights
⚠️ Warning: Structural cracks require immediate professional attention
Pressure Test Plumbing Lines
Isolate and pressure test individual plumbing lines to identify which line is leaking
⚠️ Warning: Requires specialized equipment - recommend professional service
Professional Detection Methods
Acoustic Detection
Electronic listening devices detect sound of water escaping underground pipes
Camera Inspection
Fiber optic cameras inspect inside pipes to locate cracks and breaks
Pressure Testing
Isolate and pressurize individual lines to identify which pipe is leaking

Leak Prevention Strategies
Prevention Tips
Maintain Water Chemistry
Balanced water prevents equipment corrosion and surface deterioration that cause leaks
Regular Equipment Inspection
Check pump seals, o-rings, and gaskets monthly. Replace worn parts before they fail
Winterize Properly
Blow out lines and add antifreeze to prevent freeze damage that causes pipe cracks
Monitor Water Level Weekly
Track normal evaporation rates. Quick detection means smaller, cheaper repairs
Professional Annual Inspection
Have plumbing pressure tested and equipment thoroughly checked each spring
