Lawn sprinklers make it easy to water a lawn and keep it green in even the driest of summers. Sprinkler systems either work on an automatic pilot, turning on at specified times of the day, or work manually. With either method you're bound to have a problem eventually. Troubleshooting lawn sprinklers is one of the most difficult tasks of a gardener, but knowing the basics can keep you from kicking at the dirt.
System will not turn on
Check to see whether your system has a rain sensor. Turn it to the off position or to the bypass setting to see if it has accidentally been triggered, causing your sprinklers to not turn on.
Check whether the water for the system is turned on (in case it has been turned off accidentally).
Look at the filter on the sprinkler system hose and check for dirt or debris, which may be clogging the water flow. Clean the filter if necessary.
Check the power source of the sprinkler system and ensure it is not turned off. Also, check for faulty fuses. Replace any faulty fuses as required.
Check for leaking nozzle heads along your line to make sure there isn't any flooding. If the sprinkler nozzle is at the end of your sprinkler line at the bottom of a hill, water may run downhill after the supply has been shut off and cause flooding. Install a check valve along the line to solve this problem.
Look at all the sprinkler heads for damage, such as cracking or splitting due to mowing. Replace heads as necessary.
Clean the sediment filter to solve water pressure issues. The sediment filter is near where the water exits the house.
Remove the head of the sprinkler if it pops up from the yard but does not spray water. Remove the finger filter and clean as necessary.
