In this video, Kevin Ross discusses the essential preparations for the winterization of irrigation systems, affectionately known as Blowout. He emphasizes the importance of thorough system checks and running the system multiple times before the blowout to ensure optimal performance. Key tips include maintaining a maximum pressure of fifty PSI, following specific procedures with quick couplers, and shutting down the system a day in advance. He also highlights the need for ear protection due to noise levels and suggests providing food and drinks to boost staff morale. Finally, he encourages gathering the team post-blowout to address any unresolved issues.
