Students at Gunnison Elementary School got an unexpected one day vacation on Monday after a problem with a main water line over the weekend. According to South Sanpete School District Superintendent Kent Larsen, a joint on a pipe under a thrust block failed, causing an elbow to rupture. Repairs were made over the weekend, but due to the cure time for the new joint and thrust block, school was cancelled for Monday. Larsen said he expects things to be back to normal on Tuesday.
