When a water line freezes, water flow to faucets or appliances is significantly reduced or completely stopped. This can lead to pressure build-up within the pipe, potentially causing the pipe to burst and result in water damage. To mitigate the issue, identify the frozen section of pipe (look for frost or the coldest segment) and apply gentle heat using a hairdryer, heat lamp, or warm towels. Never use open flames. Keeping cabinet doors open to allow warmer air to circulate around pipes can also help prevent freezing.
