Did you know that the number one way swimming pools lose water is through evaporation? According to the Department of Energy, 70% of water loss in pools and is through evaporation. Evaporation occurs whenever you expose wind or air to the surface of your pool. Water molecules rise to the surface, form into a vapor and eventually get released into the air.
One sure way to determine whether your pool is losing water from evaporation or from a leak is to perform a water bucket test. Fill your pool to its normal level.
Using a bucket, fill it to 1 inch from the top with pool water.
Place the bucket in the pool at about five inches. You can set it on the first or second step of your pool.
Mark the water level inside the bucket and the water level outside the bucket using a marker or piece of tape. After 24 hours, compare the two water levels. If the water level outside of the bucket dropped more than the water level inside of the bucket, then you likely have a pool leak.
Losing water to evaporation is normal. One way to prevent swimming pool evaporation is to use a swimming pool solar cover. Not only does it prevent water from escaping your pool, it also traps any heat you have gained from the sun or pool heater.
