We live in an older home and recently encountered a leaking copper pipe in the kitchen ceiling. When the technician opened the ceiling he discovered that the size of the pipe is no longer available. In addition to this hurdle that had to be dealt with, the tech discovered that the main water shut off valve was ancient and simply would not turn with the tool that he had in the truck. This is a long story. Bottom line - the tech (Brian) was smart, hard working and resourceful. He fixed the leak - life is now back to normal. Thank you Brian - you are a true renaissance man!
