Service for frozen pipe. Customers water was converted from well to city and the softener and well tank were still in the loop but doing nothing. A 45 elbow burst after freezing connected to the softner so we removed the non working softener and cut the well tank out of the loop and re piped from before the softner to after the well tank and bypassed the old system. They are no longer in the loop and the bursted elbow was replaced. . All working properly at at this time. Customer is satisfied with service.
