Homeowner called us out due to a water stain in the ceiling. After cutting the ceiling open in basement, there was water running along the hot supply piping but no obvious rupture. After further investigation and tracking the lines run, I found wet spots and moisture behind the water heater in the garage. Opened the wall being the water heater, inside the dogs play area, and found the ruptured Uponor piping. Cut the section out and replaced it with new piping and fittings. Tested and checked for leaks. *Homeowner is aware of high pressure at this time.
