Hello - first time in this forum, and I have a question about a lawn sprinkler system. I had an inground system installed about 3 years ago (new construction site, sod installed after the sprinklers). Now that the ground has settled, several of the heads have sunk down 1"-2" below the ground surface, in some cases preventing full clearance to pulsate when the sprinklers are on. Question: Do I need to dig out each head individually and re-set, or can I adjust the heads by trying to pull them up? My neighbor said if the ground is wet around the head, I can take a shovel and pry the head up a little bit. Sounds good, but sounds like a sure way to break it off (either above or below the surface). Appreciate any suggestion on the best way to go about this.
