POOL LEAK VS EVAPORATION: HOW TO TELL THE DIFFERENCE

All pools lose water through evaporation.

In Florida, a pool may lose approximately:

• 1/8 inch to 1/4 inch per day
• 1 to 2 inches per week during hot weather
• More water during periods of high temperatures, low humidity, and strong winds

Factors that increase evaporation include:

• Hot weather
• Direct sunlight
• Wind exposure
• Heated pools
• Water features
• Low humidity

Small amounts of water loss are expected and do not necessarily indicate a leak.

YOUR POOL IS LOSING MORE THAN 1/4 INCH OF WATER PER DAY

While evaporation varies depending on weather conditions, excessive water loss may indicate a leak.

If you frequently need to add water to maintain proper levels, further investigation may be necessary.

YOUR AUTO-FILL SYSTEM RUNS CONSTANTLY

A constantly running auto-fill system can be one of the first signs of a hidden leak.

Many homeowners do not realize water is escaping because the auto-fill continuously replaces lost water.

YOU NOTICE WET AREAS AROUND THE POOL

Evaporation does not create:

• Wet spots
• Soft soil
• Standing water
• Sinkholes

These symptoms often indicate that water is escaping underground.

YOUR WATER BILL HAS INCREASED

A sudden increase in water usage may suggest a hidden leak rather than normal evaporation.

THE POOL WATER LEVEL STOPS AT A CERTAIN POINT

If the water level consistently drops to the same location and then stops, a leak may exist near that level.

This commonly occurs with:

• Skimmer leaks
• Pool light leaks
• Tile line leaks
• Structural cracks

One of the easiest ways to determine whether your pool is losing water due to evaporation or a leak is by performing a Bucket Test.

This simple test compares water loss inside a bucket to water loss in your pool over a 24 to 48-hour period. If the pool loses significantly more water than the bucket, a leak may be present.

A Bucket Test is often the first step homeowners take before scheduling professional leak detection.

Learn how to perform the test correctly by reading our complete Bucket Test Guide.

If the Bucket Test suggests a leak, several areas may be responsible.

POOL SKIMMER

Cracks around the skimmer throat are a common source of leaks.

POOL MAIN DRAIN

Leaks can occur in the drain housing or connected plumbing lines.

POOL LIGHTS

Water can escape through cracks around light niches and conduit fittings.

RETURN LINES

Underground return plumbing can develop leaks over time.

SUCTION LINES

Leaks in suction plumbing may cause water loss and air bubbles in the system.

EXPANSION JOINTS

Damaged expansion joints around the pool perimeter can allow water to escape beneath the deck.

In most cases, no.

While Florida weather can accelerate evaporation, losing multiple inches of water within a short period often indicates a leak.

Professional testing may be necessary to determine the source.

You should consider professional leak detection if:

• The Bucket Test indicates a leak
• Water loss exceeds normal evaporation
• Your auto-fill runs constantly
• Wet spots appear around the pool
• Your water bill suddenly increases
• The water level repeatedly stops at the same point

Professional leak detection can identify the exact source of water loss and help prevent unnecessary repairs.

Many pool leaks are hidden underground or within the pool structure.

Without proper testing, homeowners often spend money repairing the wrong area while the actual leak continues.

Professional leak detection helps:

• Confirm whether a leak exists
• Identify the exact source
• Reduce water waste
• Prevent structural damage
• Save money on repairs
