What is a common warning sign of a pool leak?

A common warning sign of a pool leak is an unexplained drop in water levels. When water is consistently disappearing from the pool without a clear reason, it indicates that there may be a leak either in the pool structure, the plumbing lines, or other associated equipment. Monitoring water levels is crucial; if the water loss is greater than what would typically occur due to evaporation, it suggests that a leak may need to be investigated.

In contrast, while increased algae growth may suggest inadequate sanitation or maintenance, it does not directly indicate a water leak. Similarly, the presence of too much foam could be linked to oils or contaminants in the water rather than revealing any structural issues related to leaks. A strong chemical odor typically points to an imbalance in pool chemicals or chlorine levels, which may affect water quality but does not imply that there is a leak occurring.
