This straightforward procedure helps determine if a swimming pool is losing water due to evaporation or a leak. It involves filling a container with water, matching the pool’s water level, and monitoring both over a period, typically 24 hours. The rate of water loss from the container is compared to the pools decrease in water level to ascertain the source of the loss.
Identifying water loss reasons is economically important. Distinguishing between standard evaporation and a leak can save money on unnecessary water bills and costly repairs. Historically, pool owners relied on less precise methods to diagnose water loss, making this method a more reliable diagnostic tool. Implementing such test is crucial to confirm the potential leak before proceeding to more complex investigations.
