How should irrigation equipment be winterized?

The correct approach to winterizing irrigation equipment is by draining water and protecting components from frost. During colder months, water left in the irrigation system can freeze, leading to damage such as cracked pipes or broken fittings. Draining water ensures that there is no liquid left to freeze within the system.

Additionally, taking measures to protect components from frost, such as insulating pipes or using specially designed frost protection devices, helps to safeguard the system against freezing temperatures. This proactive approach is critical for maintaining the integrity and operational capability of irrigation equipment, ensuring that it will function properly when the spring season arrives.

Other methods, such as increasing water flow, may inadvertently lead to more water remaining in the system, which is counterproductive for winterization. Covering equipment with tarps might offer some level of protection from snow or debris but would not address the main issue of water freezing inside the system. Adding antifreeze is generally not recommended for irrigation systems, as many antifreeze products can be harmful to plants and the environment, making it not a suitable choice for irrigation winterization.
