Water loss is something every pool owner encounters at some point. A certain amount of it is completely expected. Evaporation, splashing, and normal swimmer activity all contribute to a gradual decline in water level that requires occasional topping off throughout the season. What is not normal is a water level that drops faster than it should, consistently, regardless of weather or bather load. At the Jersey Shore, where pools often sit for days between visits and a problem can develop significantly before anyone notices, knowing how to identify a potential leak early is particularly valuable.
