The answer to 'best time for sprinkler system' is that the best time to install or activate a sprinkler system is in the spring, typically between April and May. This allows the system to be up and running before the peak watering season of the summer months.
Sprinkler systems should be turned on and inspected annually to ensure they are functioning properly and efficiently. This includes checking for any leaks, broken sprinkler heads, or other issues that may have developed over the winter. By activating the system in the spring, you can identify and address any problems before they lead to water waste or damage to your landscaping.
