How Do You Turn On an Irrigation System?

Steps to Turn On a Sprinkler System:

Check the System Components:

    • Inspect the sprinkler heads, valves, and pipes for any visible damage or debris. Clean any dirty or clogged sprinkler heads.

Turn On the Main Water Supply:

    • Locate the main water supply valve for the sprinkler system. This is usually near the main water meter or in a basement, crawl space, or utility room.
    • Slowly turn the valve counterclockwise to open it. Opening it slowly helps to prevent a sudden surge of water, which could damage the pipes or sprinkler heads.
    • You will then need to go to your backflow and...

Open the System Valves:

    • If your system has manual shut-off valves, open them to allow water to flow into the system. These valves are typically located near the main water supply or along the main line of the sprinkler system.

Activate the Controller:

    • Go to your sprinkler system controller (timer) and ensure it is plugged in and powered on.
    • Set the current date and time on the controller.
    • Program the watering schedule according to your lawn’s needs and local watering regulations. This includes setting the start times, duration, and frequency for each zone.

Test Each Zone:

    • Manually test each zone by activating it through the controller. This allows you to check for proper operation and coverage.
    • To do this, select the “Manual” or “Test” mode on the controller, then activate each zone one at a time.
    • Walk around and observe each zone as it runs to ensure the sprinkler heads are popping up correctly, spraying evenly, and that there are no leaks or malfunctions.

Adjust Sprinkler Heads:

    • If necessary, adjust the sprinkler heads to ensure they are covering the desired areas without overspraying onto sidewalks, driveways, or buildings.
    • Make any needed adjustments to the spray pattern, distance, and direction.

Check for Leaks:

    • While the system is running, look for any signs of leaks in the pipes, valves, or sprinkler heads.
    • If you find any leaks, turn off the system and repair the leaks before continuing.

Set the Controller to Automatic:

    • Once you’ve tested all zones and made any necessary adjustments, set the controller to “Automatic” mode so that it follows the programmed schedule.

Tips:

  • It’s a good idea to turn on your sprinkler system in the early spring after the last freeze to avoid damage from frozen pipes.
  • Regularly inspect and maintain your system throughout the watering season to ensure it continues to operate efficiently.
  • Be aware of and follow any local watering restrictions or guidelines to conserve water and comply with regulations.

By following these steps, you can effectively turn on your sprinkler system and ensure it operates correctly.
