Pool water evaporation

How much water evaporates from a pool each day?

Pools typically lose about 4-6 mm of water through evaporation every day, so some regular attention to water loss is normal. Every few days you might have to add some water to make up for the loss. If you're adding water more frequently or every day you might have a bigger problem. At this point you might want to implement the Bucket Test. It's easy and will quickly tell you there's a bigger problem with your pool.

There are several factors in the rate of evaporation. The humidity of your location, exposure to wind and lengthy exposure to direct sun can all affect the pool water level. If you've factored these conditions into your evaluation and still feel your pool or spa water levels are dropping too quickly, it's time to contact Canadian Leak Detection.
