I don't have a sprinkler system, don't really have a lawn yet. I just put out tubing with metered jets on a timer, have to do the first two years to establish the trees then it comes out.
You probably don't get the heat we do here during the summer. I like ours, beats hauling hoses. We came back from our last deployment (yep she was deployed for a year) and bought the sprinkler system.
