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

if you have head to head coverage, not arc to arc, then you will not have dry spots.

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.

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)

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

And JMHO, but I think Trugreen is a rip-off and a waste of money. I had them once, and watched the knuckledragger "treat" my lawn, a friggin' toddler could have done a better job with the hose. Took him all of 5 minutes to unroll, do front and back, roll up, and leave. I could have pissed on the lawn and covered it better.

Canceled them immediately, they've been bugging me ever since to sign back up, and that was 10 years ago.

the reason i water twice a day is early in the morning so the lawn gets a nice watering before its hot and in the evening so the lawn gets a nice drink and cooled off after a dry hot day. don't water in the middle of the day as the water will be wasted through evaporation and water droplets can burn grass much like a magnifying glass

My Trugreen guy is an older gentleman. I think he has OCD and he always does a pretty good job for me. I have been here on several occasions and watched him work without him knowing about it. Anyhow, that is a different story.

I am pretty sure I have "head to head" coverage on my sprinklers. There are five zones in the back yard and each zone has four heads on it. So that means I have 20 sprinkler heads covering an area that is approximately 6400 sq. feet.

Special thanks to the forum member who called me to offer his help.

then it might not be a bad idea to replace your nozzles (head replacement is only needed for heads that are broken or not functioning properly like a rotor that wont rotate) and then make sure you are getting enough water on at the right times of day.

Not to hijack but how long are you running your sprinklers when you run it twice a day everyday? Popups and rotors?
