Preparing irrigation sprinklers for spring is important. First, carefully inspect pipes, valves, and sprinkler heads for any winter damage. Slowly open the main water supply to prevent pressure surges. Then test each zone to find problems with function and coverage. Adjust sprinkler heads, clean nozzles, and clear debris to ensure best performance. Check the whole system for leaks, pressure issues, and broken parts. Set the controller to the right watering mode for the plants and program it to shut off. Examine water sensors, like rain and moisture detectors, to make sure they work properly. Also check the backflow preventer for water safety. A thorough review ensures all adjustments and settings are optimized for effective irrigation. This helps avoid expensive repairs and keeps your garden healthy all year round.
