What device is commonly used to check for leaks in pool systems?

A leak detection system or dye testing is commonly used to check for leaks in pool systems because it allows for precise identification of the location and source of a leak. Leak detection systems can utilize various technologies such as acoustic sensors or pressure testing to find leaks in pipes or the pool structure itself. Dye testing involves introducing a dye into the water near suspected leak areas; if there is a leak, the dye will be drawn into the opening, confirming its presence.

This approach is particularly effective as it targets common problem areas, including skimmers, main drains, and the pool shell. Unlike other options, which serve different functions, leak detection methods specifically focus on identifying unseen leaks that can lead to water loss and structural issues if not addressed promptly. Understanding these practices is crucial for maintaining the integrity and safety of the pool system, as undetected leaks can result in significant water loss or damage over time.
