Occasionally lawn sprinkler heads need to be replaced. Some reasons for replacing sprinkler heads include getting clogged with sand, breaking from freezing, or getting hit by a lawn mower. Luckily, if you have to change lawn sprinkler heads, rest assured that it's one of the easiest maintenance tasks that you can perform on your home sprinkler system. That's why if you have good home improvement skills, try doing this yourself so you can save your pocketbook some money by not having to call a repair person.
Find the manufacturer and model number for the sprinkler head. This information is located on the top of the sprinkler head.
Take the head information to your nearest irrigation supply store and purchase a new sprinkler head.
Take your shovel and dig a 12-inch square around the sprinkler head a few inches deep. Take the sod out in a manner that it can be easily replaced. Dig carefully so the sprinkler piping is not damaged.
Unscrew the old head by turning it counter-clockwise with your pipe wrench. Screw in the new head clockwise until it's firm and snug.
Replace the dirt and sod back around the sprinkler head. Your sprinkler head should now be properly replaced.
