Annual Water Loss vs Pool Season Months
Formel
## How to Calculate Pool Evaporation Swimming pools lose significant water to evaporation, especially in hot, dry, or windy climates. ### Formula **Evaporation (gal) = Pool Area * Evap Rate * Months * 0.623 * (1 - Cover Reduction)** ### Typical Evaporation Rates - Humid climate: 2-3 inches/month - Moderate: 4-5 inches/month - Arid/hot: 6-8 inches/month A pool cover reduces evaporation by 70-90%.
Lösungsbeispiel
A 450 sq ft pool evaporating 4 inches/month for 6 months without a cover.
- 01Gross evaporation: 450 * 4 * 6 * 0.623 = 6,729 gallons
- 02Net evaporation (no cover): 6,729 gallons
- 03Monthly loss: 6,729 / 6 = 1,122 gallons
- 04Cover would save: 6,729 * 70% = 4,710 gallons
Häufig Gestellte Fragen
How much water does a pool lose to evaporation?
A typical 450 sq ft pool can lose 6,000-15,000 gallons per season depending on climate. Hot, dry, and windy conditions dramatically increase evaporation.
How effective are pool covers?
Pool covers reduce evaporation by 70-90%, saving thousands of gallons per season. They also reduce heat loss, chemical use, and debris, paying for themselves in 1-2 seasons.
How do I know if I have a leak vs evaporation?
The bucket test: place a bucket of water on the pool step. Mark both water levels. After 24 hours, if the pool dropped more than the bucket, you likely have a leak.
