The answer to how to care for irrigation installation is to regularly inspect, maintain, and winterize your irrigation system. This will ensure it functions properly and lasts for many years.
Start by visually inspecting your irrigation system at least once a month during the growing season. Look for any leaks, broken or clogged sprinkler heads, and signs of damage. Adjust sprinkler heads as needed to ensure even coverage and prevent overspray. Clean the system's filters and remove any debris. In the fall, shut off the main water supply, drain the system, and blow out any remaining water to prevent freezing damage over the winter.
