The process of introducing pressurized air or water into the subterranean conduits of a swimming pool circulation system to identify leaks. This diagnostic technique assesses the integrity of the plumbing that facilitates water movement to and from the pool equipment, such as pumps, filters, and heaters. For instance, a technician might connect a pressure testing apparatus to a pool return line and introduce air to a specified pressure, observing for any pressure drop indicative of a leak.
Leak detection is crucial for maintaining the efficiency and longevity of a swimming pool. Undetected leaks can lead to significant water loss, increased utility bills, and potential damage to surrounding structures due to soil erosion or saturation. Historically, visual inspection and guesswork were common methods; however, pressure testing offers a more accurate and reliable means of pinpointing subsurface leaks, preventing costly repairs and environmental impact.
