Customer reported warm flooring around refrigerator. Performed several test including checking the meter as well as isolating the water lines feeding the house and doing a pressure test of the system. The meter did not move after watching for 10 minutes and the gauge never lost pressure when performing the pressure test. All of this leads me to believe there is no active leaks. Removed fridge and checked flooring around fridge. Temperature under fridge was approximately 80 degrees while rest of floor was approximately 70. After I removed fridge the flooring located under fridge began to cool down. I believe the cause of the warm flooring is due to the motor of the refrigerator running and warming the walls, and flooring surrounding it.
