Aging Copper in Original Summerlin Villages (1990s Builds)
Homes built in Summerlin's original western villages, including The Hills, The Trails, The Arbors, and The Canyons, were constructed primarily in the 1990s with copper supply lines. These pipes have now been exposed to Las Vegas Valley hard water for 25 to 35 years. Las Vegas Valley water carries approximately 280 parts per million of dissolved minerals, among the hardest municipal water in the United States. Hard water causes pitting corrosion inside copper pipe walls, thinning them continuously from the inside out. When copper pipe walls thin sufficiently, pinhole leaks develop. Multiple pinhole leaks in different locations of an original Summerlin village home indicate that the pipe walls have thinned throughout the system rather than at isolated points, making repiping a more practical long-term solution than continued spot repairs.
