What is 'dry line shock'?

'Dry line shock' refers to the phenomenon that occurs when water travels through dry, empty piping for a significant distance before reaching plants or soil. When water movement is initiated in piping that is not filled with water, it creates a sudden change in pressure once the water begins to flow. This can lead to turbulence and shock waves within the pipe system. If the water travels with little to no resistance, it can impact the efficiency of irrigation systems, potentially causing damage or making the watering process less effective. Recognizing this concept is important for irrigators to ensure that systems are properly primed and functioning to avoid unintended consequences like air locks or uneven water distribution. Understanding how dry line shock occurs helps in troubleshooting and designing better irrigation practices.
