Have any of your pop-up sprinkler heads been damaged by a lawn mower or simply by getting walked on? Are you getting tired of seeing your pop-up sprinkler heads spray unevenly, or even worse, leak water onto the grass and pavement and down the drain? Repairing a broken sprinkler head is actually a lot simpler than you may realize.
Remove the sprinkler head
With either a serrated knife or a pointed shovel, dig about six inches deep into the lawn around the sprinkler head. (Take care not to hit any water lines.) Pry up a section of turf about two or three inches thick, setting it aside along with the dirt surrounding the sprinkler head to replace later. Dig until you reach the water-supply pipe, which should be about six to eight inches below the grass.
Clear your way down to the riser, a short vertical pipe connected to the water-supply pipe. Carefully unscrew the old sprinkler body, taking care not to let dirt fall into the riser or to damage the threads on either end.
Buy a new sprinkler head
Take the old sprinkler to the home improvement store and choose a new one that matches its size. Ideally, you’ll find the same make and model as your original sprinkler, but if you can’t, choose one that has same diameter female opening at the bottom and the same overall length as the original. While you’re out, make sure to pick up some Teflon tape.
Replace the sprinkler head
When you get home, wrap the Teflon tape around the threaded male end of the riser and tightly screw in the new sprinkler body. Then turn on the water line for a minute to get all of the dirt out that may have fallen into the line.
Turn off the sprinklers, pull up the riser using the flush-plug ring and then unscrew the flush-plug. Put in the plastic filter screen and screw on the nozzle, twisting it to align the spray pattern. Ensure it sprays on the lawn and not on surrounding areas. Finally, turn off the water and replace the dirt and turf around the sprinkler.
