Homeowner called us out due leak on pipe above water heater. After further discussion and assessment, we ended up replacing the cold side dip tube on the left water heater, ball valve, incorrectly installed swing valve on recirc line, and we installed a new shutoff form the main incoming line of both heaters, a check valve for the main cold line, and a groudfos alpha recirc pump. All work was tested and checked for leaks. The recirc pump was set to temperature control with homeowner.
