Upon arrival spoke with the customer about water coming from the ceiling in their dining room. A previous repair was made in this area and one roughly 10 ft away in the kitchen on the uponor recirculation line. Cut the ceiling open in multiple spots. All wood was dry and a very small amount of water was present on the piece of drywall that was removed from the dining room. Turned on the water to the home and bled down the recirculation line. No leaks, drips or drops were observed. Hot line, cold line and recirculation loop were all accessible in the chase the hole was cut. Removed insulation from piping. Spent roughly two hours looking for leaks but could not reproduce. Customer was charged for a leak search today and in the event the leak shows again I will credit the leak search towards any repairs necessary.
