I have a pop up sprinkler system in my backyard. There is barely enough pressure to pop up the heads. My lawn is dying. My wife had some guy install them while I was deployed to the middle east, and he has wisely disapeared. My front yard sprinklers came with the house and they have more than enough pressure. Is it possible that the sprinkler heads need to be replaced or upgraded or is there a problem with the water supply?
