Help! I need a sprinkler guy.

i was a landscaper for 7 years and am rainbird certified either way if you have head to head coverage, not arc to arc, then you will not have dry spots. i water my lawn twice a day every day just for an appropriate amount of time and i dont have any brown spots despite the heat. it you're using rotors i advise rainbird 3500's from cps of other irrigation supply places. for popups rainbird 1804's have always worked well for me.

edit: just straightening your heads and raising them to the proper level and cleaning around them will help tremendously

I think I have some sort of arcing going on. Last year, I had several green "rings" of grass about 14 feet from my sprinkler heads. How do I get "head to head" coverage?

Thanks.

show us an up close picture of the sprinkler head (rotor) running and not running.

head to head coverage is where the arc from one head reaches all the way to another head so their water arcs are overlapping. arc to arc coverage is where just the water arcs meet. to get this if you don't already you need to either install farther throwing sprinkler heads or additional sprinkler heads. also make sure the increased water demands can be handled by your gpm flow and psi otherwise you will need to add valves and zones

i bet you have a dead rotor, somewhere off to the left (from the picture)
the head in the middle is turning, but it's not getting water from the other two that are supposed to hit it.

it's also just damn dry and almost all residential systems SUCK. (low bidder and all).

30 minutes on a good rotor zone isn't enough
looks like that gets solid sun all day.

keep the grass long, as long as possible. hell i don't even mow til it cools down and i just can't stand the shagginess. let the grass shade the ground.

make sure that all the rotor's are turning first, and getting head to head coverage (each spot in the lawn should be hit by at least 3 sprinklers)
