A. Mike Ducato. Disconnect all outside hoses to prevent freezing. If there is a shut off for the hose in the basement or crawl shut these off as well. open the cabinet doors below the sink to promote air flow to the pipes. Keep the garage doors closed whenever possible particularly if there are water pipes present. Finally keep a hair dryer handy just in case of a frozen pipe. This will thaw the pipe out and allow water to flow again. If you notice any split in the pipes before you thaw them, call a licensed plumber immediately.
