How to Tell If Your Swimming Pool Has a Leak

If your pool water level keeps dropping and you're constantly refilling it, you might be wondering: “Is it evaporation—or do I have a leak?” While some water loss is normal, excessive or sudden drops could point to a bigger problem.

Here’s how to tell if your swimming pool has a leak and what to do next.

Pools naturally lose a little water from splashing, backwashing, or evaporation—but if your pool seems to be losing more water than usual, you could have a leak. Pool leaks can go unnoticed for weeks or months, leading to higher bills, damaged equipment, and even structural issues.
