How do I Thaw a Frozen Water Pipe?

well, if i were u, i would use a blow drier, turn the heater up, or just open a window if its really hot outside so the heat could warm up the pipe (if there are windows near by)

start out with cold water until frost no longer forms then gradually add heat starting low & increasing gradually until ice breaks loose then as water starts flowing, it will thaw the rest. If no heavy frost on pipe force air heat may do,but start low as expansion will occur if too fast

You could get pipe warmers.
