Why Is It Important to Blow Out Your Sprinkler System Before Winter?
It is important to blow out your sprinkler system before winter to prevent freezing and subsequent damage to the pipes and system components. If water remains in the pipes, it can freeze as temperatures drop, leading to cracks or bursts that can be costly to repair.
The National Association of Landscape Professionals (NALP) emphasizes the significance of winterizing irrigation systems to protect them from freezing damage. Proper maintenance can extend the lifespan of your sprinkler system.
The underlying cause of the issue is the expansion of water when it freezes. Water expands by approximately 9% as it transitions to ice. This expansion can create pressure within pipes, leading to breaks. Additionally, sprinkler heads and valves can also be affected, resulting in significant repair costs.
One main technical term related to this process is “winterization.” Winterization is the process of preparing your irrigation system for cold weather by removing or draining water. It ensures all components are safeguarded against freezing conditions.
During winterization, the process typically involves using compressed air to force out any remaining water from the system. Compressed air enters the system and displaces the water in the pipes, allowing it to escape and leaving the system empty and dry. This step is crucial for preventing ice formation, which can cause pipe ruptures and damage to the entire irrigation system.
Specific conditions that contribute to the issue include temperatures dropping below freezing and prolonged exposure to those conditions. For example, if the temperature remains consistently below 32°F (0°C) for an extended period, the risk of ice forming in the irrigation system increases significantly. Neglecting to blow out the system before such cold weather can result in extensive damage that requires more than just repairs, potentially necessitating a full replacement of the system components.
