If Your Pipes Freeze . If you know where the lines are frozen, you can attempt to thaw them with a hair dryer. With the dryer on a low heat setting, wave the warm air back and forth along the line. It's a slow but safe process. Don't use an open flame to thaw frozen lines.
Open flames can be a fire hazard and overheating a single spot can burst the pipe.
Know your main control valve location and be prepared to turn it off. The line you are thawing may already be broken, cracked or split. Water could come gushing out once the line thaws. If your Pipes Break . . . If you can't find the main control valve, or if the valve does not work and water is leaking in the house, call the Topeka Water Division at 368-3830.
