Dealing with frozen pipes can be an unpleasant and expensive job. You can reduce the chances of your pipes freezing by taking some precautionary measures before extreme temperatures hit. Here are a few tips to help you avoid potential catastrophe: Insulate any exterior wall pipes; open cabinet doors to allow heat from your home to reach sink pipes; trickle water from faucets- moving water is less likely to freeze. When traveling away from home, do not set your thermostat any lower than 55 degrees. If your pipes do freeze, you should open the faucet letting water pass through, even if only a trickle- this will help the pipes to warm faster. More here
