When considering when to reactivate your sprinkler system in the spring, it’s important to avoid turning it on too early to prevent potential damage such as frozen pipes and leaks in case of unexpected cold weather. This can not only be costly but also result in wasted water. To determine the right time, ask yourself if it is safe and necessary based on the current weather conditions. It’s advisable to wait until the risk of freezing has passed and the soil has dried out to benefit from irrigation, according to Jeff Johnson, a senior product manager at Rain Bird Corporation. Consider factors like the last average frost date in your area and the soil conditions. Additionally, pay attention to the moisture level in the soil and the grass’s appearance to decide if irrigation is needed. Be cautious of protecting your system during cold weather by using thermal insulation for components above ground, especially backflow valves. The timing of starting up your system may vary based on the regional climate, with different considerations for northern, transitional, and southern regions.
Proper irrigation management is crucial to the health and well-being of plants, as too much water can lead to overwatering when plants do not yet require excessive moisture. Startups for irrigation systems may commence as early as February or March, particularly in regions with minimal spring rainfall, such as arid and desert climates.
In desert and arid climates, it is essential to initiate the irrigation system early to avoid plant stress as temperatures increase. The startup process typically begins between February and March, although certain areas may necessitate year-round irrigation with adjustments made according to the seasons.
When preparing to reactivate the irrigation system, it is vital to undertake some fundamental precautions. Johnson advises, “Inspect for any visible damage, ensure the ground has thawed completely, and gradually pressurize the system to prevent pipe damage or potential flooding.” Additionally, it is advisable to check for leaks, clean the sprinkler heads, and test each zone to verify proper functionality.
Once past the average last frost date, with the soil fully thawed and the turf displaying signs of dryness, the following steps should be taken at a minimum to initiate the irrigation system:
– Verify the settings on the controller and replace the backup battery if necessary.
– Clear any dirt and debris obstructing sprinkler heads.
– Assess nozzles, valves, pipes, and other components for damage and replace them if required.
– Inspect valves for leakage and confirm they are functioning correctly.
– Gradually open the water valve to prevent a water pressure surge that could potentially harm the system.
– Ensure the water pressure falls within the recommended operating range, typically between 40-65 PSI.
