Our yard had several large brown spots which looks like the sun was burning the grass and I wish that someone from your company would have called or E-mailed me so that we could have fixed the problem quicker. I now have changed 12 of the sprinklers at the front of the house and hopefully the grass will get green soon. We live in Toronto and if my son did not arrive at the house last week, I would be afraid of how bad the grass would have been. Mike Panch.
