I had a broken water pipe repaired in February 2014. The repair was made using Pex flexible waterline laid in a loop that came from original waterline up to within an inch of the top of the ground. The bill was over $400. This spring our sprinkler company saw this and advised that waterline is supposed to be at least 18 inches below grade. I have called Ace Plumbing, and they said they would look into it. I will revise my review after they determine what action they will take.
