On average, swimming pools lose about a quarter of an inch of water each day, yet variations in wind intensity, humidity and sunlight can drastically change water loss rates.

Leaks in your pool system may be difficult to find for one of two reasons.

The average swimming pool will lose anywhere from 1/4″ to 1″ per week.
