How to Troubleshoot Toro Sprinklers
- 1). Reset the "season adjust" button and shut off all but one of the start times for the unit if the watering cycle repeats itself.
- 2). Turn on the timer, check the fuses to see if they need changing, repair the valve wire or look at the timer program if the lawn is not being watered.
- 3). Turn the supply valve to the "on" position. Replace the valve solenoid and open it completely counterclockwise if you don't notice any water at the sprinkler heads.
- 4). Check the irrigation pipes for cracks or damage and replace any bad parts if exterior water is leaking at the valve.
- 5). Clean the screen so it is clear if water does not spray from the nozzle. Clean debris out and replace the heads if necessary if they do not rotate.
