Spring Maintenance for Sprinkler Systems

Spring is just around the corner and it is time to start thinking about getting your automatic sprinkler system up and running again. Your system has probably sat dormant for the last few months so it is time to check it out to make sure it is in good working order.

The following checklist for bringing your sprinkler system out of hibernation comes from Hunter Industries, maker of residential and commercial irrigation products.


  • Turn all manual drain valves to the "closed" position before turning on any water to the system

  • Turn on the main system water valve slowly and allow the water to fill the pipes gradually. If the valves open too quickly, the sprinkler main lines are subjected to high surge pressures, uncontrolled flow and water hammer.

  • Manually activate each zone valve from the controller to maker sure the zone is operating correctly.

  • Check the operating pressure. (low pressure indicates a line break or missing sprinkler)

  • Check for proper rotation of sprinkler heads and adjust accordingly for adequate coverage.

  • Check and clean filters on poorly performing sprinklers.

  • Reprogram the controller for automatic watering.

  • Replace the controller back-up battery if necessary.

  • Uncover and clean the system rain sensor, if applicable.

  • Finish and clean any in-line filters for drip irrigation zones.
