WinterizationWithout proper preparation, your sprinkler system might be damaged by freezing temperatures. Here are some tips from Rain Bird on how to prepare your irrigation system for winter conditions if you live in a region where it freezes. Please download the Rain Bird Homeowners Guide to Winterization for detailed instructions on how to prepare your irrigation system for the winter months.

When the sound of water rushing through the pipe is detected, fully open the ball or gate valve.

Remove the riser and nozzle from the sprinkler body if any of the sprinklers aren’t working. Remove all dirt from the riser and replace it. Look for any areas of water on the lawn that might indicate damaged pipes.

Turn on the main water supply for the sprinkler system. Using pliers, open the ball or gate valve one-third of the way to let water gradually fill the mainline.

Verify that the correct date and time are displayed on the Rainbird controller by looking at it. To set, turn the dial to “Set Current Date. “To set the day, press the up and down arrows. To enter the month, select the “Manual Start/Advance” button. The month can then be chosen by using the up and down arrows. Repeat the process to set the year and time.

Reset the sprinkler watering times, if necessary. Move the dial to “Auto. ” Slide the program switch to A, B or C. Turn the dial to “Set Watering Start Times. ” Press the arrow keys to select the time.

2. Stay in control:

The controller (timer) needs to be “shut down” if your system is automatic. The “rain-mode” on the majority of controllers just turns off the signals to the valves. The programming data (start and stop times, valve run times, etc.) is retained by the controller, which keeps track of time. ) and the clock continues to run throughout the winter. The only change is that the valves will not activate. In case your controller is in charge of turning on a pump, you ought to disconnect the wires that link to the common terminals and MV (Master Valve) as a precaution. By doing this, the chance of the pump being inadvertently turned on and possibly causing damage from overheating is reduced. Turning off the controller’s power is one way to avoid utilizing the rain mode. If so, you’ll have to reset the time in the spring, along with maybe all your other settings.

1. Insulate your assets:

Shut off the water supply to the irrigation system. Your irrigation system’s primary shut-off valve needs to be shielded from freezing. Ensure that it is wrapped in insulation (a plastic bag and foam insulation tape) to shield it from the bitter cold and keep it from freezing. If you don’t already have one, you should think about making the preventative investment of installing one. Also, any above ground piping needs to be insulated. Foam insulating tubes or self-sticking tape that are frequently available at home supply stores work well.
