As winter comes to an end and the warmer months approach, it’s essential to properly turn on your sprinkler system to ensure a healthy and lush landscape. This comprehensive guide will walk you through the steps to safely and effectively activate your sprinkler system after winter, allowing for optimal irrigation performance.

How to Turn On Sprinkler System After Winter?

  • Locate the main water supply valve for your sprinkler system and ensure it is in the “off” position.
  • Slowly turn on the main water supply valve to allow for a gradual increase in water pressure throughout the system.
  • As the water pressure builds, carefully check for any leaks or abnormalities in the system, such as dripping pipes or faulty valves.
  • If your system has a backflow preventer valve, follow the manufacturer’s instructions to open it.
  • Turn on the control panel or irrigation timer and ensure it is functioning correctly.
  • Activate each zone individually and monitor the sprinkler heads for proper operation. Adjust and align the sprinkler heads as needed to ensure optimal coverage.
  • Verify and adjust the controller settings, including the watering schedule for each zone, according to your specific requirements.
  • During the initial watering cycles, closely monitor the system’s performance for any irregularities or issues.


Tips for Turning on the Sprinkler System after Winter

  • Conduct a thorough inspection of the system for any visible damage or wear, such as cracked pipes or damaged sprinkler heads. Address any necessary repairs promptly.
  • Clear debris, leaves, and obstructions from around sprinkler heads and valves to prevent clogging and ensure proper water flow.
  • Check for leaks in the connections, joints, and valves. If you find any, repair them before proceeding with the activation.
  • Gradually increase the water pressure when turning on the system to avoid sudden surges that could potentially damage the pipes or sprinkler heads.
  • Regularly perform maintenance tasks throughout the season, such as cleaning clogged nozzles and adjusting sprinkler heads for optimal performance.


How often should I water my lawn after turning on the sprinkler system?

The frequency of watering depends on various factors, including the type of soil, grass, and weather conditions. Generally, watering deeply and infrequently is recommended to promote deep root growth.
