Is my pool leaking?
To keep your pool safe from freeze, it is critical that the water level stays consistently full and free from leaks.
Some leaks are obvious water loss while others that seem minor can lead to expensive repairs.
A good example is a spa spillway that drips from underneath and into the pool. This leak allows some water to be trapped inside the spa wall. When the trapped water freezes, it can expand and damage the tile or stone work.
If you suspect instability in your water level and see no obvious sources of loss, conduct this test to determine your loss.
